Claude Opus 4.7 is a hybrid reasoning large language model developed by Anthropic and announced on April 16, 2026. It is positioned as Anthropic's most capable generally available model at launch, succeeding Claude Opus 4.6 in the Opus tier of the Claude 4 family. The model targets long-horizon agentic work, advanced software engineering, vision-heavy workflows, and enterprise knowledge tasks that previously required close human supervision.[1][2]
Opus 4.7 supports a 1 million token context window at standard API pricing, a 128,000 token maximum output, adaptive thinking, and high-resolution image understanding. It is offered through the Claude consumer apps, the Claude API, Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry. The release coincided with the introduction of Project Glasswing, a defensive cybersecurity initiative that includes the more capable but unreleased Claude Mythos Preview model.[1][3][4]
At launch Anthropic stated that Opus 4.7 outperforms Opus 4.6 across coding, multidisciplinary reasoning, scaled tool use, and agentic computer use. The company also publicly conceded that the unreleased Mythos Preview is more broadly capable. Opus 4.7 is intended to be the production model that customers can deploy at scale; Mythos remains invitation-only inside Project Glasswing. This split between a generally available frontier model and a more capable invitation-only model was a first for Anthropic and was widely discussed by AI press at launch.[5][6]
The model uses the API identifier claude-opus-4-7. It is the seventh distinct model in the Opus subfamily after Claude Opus 4, Claude Opus 4.1, Claude Opus 4.5, and Claude Opus 4.6, and the eighth Claude 4 model overall when counting Claude Sonnet 4.5, Claude Sonnet 4.6, and Claude Haiku 4.5. The release is also notable for being one of the largest day-one rollouts Anthropic has ever conducted, with the model live across claude.ai, the API, Bedrock, Vertex AI, Microsoft Foundry, Claude Code, Cursor, and GitHub Copilot within hours of the announcement.[7][16]
In the five weeks following launch, Anthropic extended the Opus 4.7 surface with Fast Mode (a higher-throughput tier that became the default for the Claude Code /fast command on May 14, 2026) and graduated Claude Security from research preview to public beta on May 1, 2026 with Opus 4.7 as its underlying engine. The model also became the anchor of a broad partner program covering CrowdStrike, Microsoft Security, Palo Alto Networks, SentinelOne, TrendAI, and Wiz, with consulting partners Accenture, BCG, Deloitte, Infosys, and PwC building deployment practices around it. At Anthropic's Code w/ Claude SF 2026 conference on May 6, 2026 the company doubled Claude Code five-hour rate limits, raised Opus API limits, announced a SpaceX Colossus 1 compute deal worth more than 220,000 Nvidia GPUs and 300 megawatts, and shipped a major Managed Agents expansion (Dreaming, Outcomes, Multiagent Orchestration, Webhooks). The following week brought Claude for Microsoft 365 general availability, the Claude Platform on AWS, Claude for Small Business, and an expanded PwC alliance covering 30,000 trained professionals.[31][32][33][42][44][46][48][50][51]
Claude Opus 4.7 was released on April 16, 2026, roughly two months after Claude Opus 4.6 (February 5, 2026) and almost one year after Claude Opus 4 and Claude Sonnet 4 (May 22, 2025). It uses the API model identifier claude-opus-4-7 with no date suffix; from the 4.6 generation onward Anthropic adopted dateless pinned snapshot identifiers rather than the previous YYYYMMDD-suffixed format.[1][2]
The Opus subfamily progression to date is summarized below.
| Model | Release date | API ID | Notable change |
|---|---|---|---|
| Claude Opus 4 | May 22, 2025 | claude-opus-4-20250514 | First Claude 4 generation Opus, hybrid reasoning, ASL-3 |
| Claude Opus 4.1 | August 5, 2025 | claude-opus-4-1-20250805 | Coding and tool use improvements |
| Claude Opus 4.5 | November 24, 2025 | claude-opus-4-5-20251101 | Pricing reduction, effort parameter, 80%+ SWE-bench |
| Claude Opus 4.6 | February 5, 2026 | claude-opus-4-6 | 1M context window, adaptive thinking, agent teams |
| Claude Opus 4.7 | April 16, 2026 | claude-opus-4-7 | New tokenizer, adaptive thinking only, xhigh effort, high-res vision |
At the time of release, the rest of the Claude family included Claude Sonnet 4.6 (released February 17, 2026) and Claude Haiku 4.5 (released October 15, 2025). Claude Opus 4 and Claude Sonnet 4 from May 2025 were officially deprecated and scheduled for retirement on June 15, 2026, with Anthropic recommending migration to Opus 4.7 and Sonnet 4.6 respectively.[2]
The roughly ten-week cadence between Opus 4.6 and Opus 4.7 was faster than the gap between previous Opus iterations. Anthropic cited three engineering investments that were ready earlier than expected: a new tokenizer, a high-resolution vision pipeline, and the consolidation of adaptive thinking as the only thinking-on mode.[7]
Post-launch updates through mid-May 2026 expanded the Opus 4.7 surface without changing the underlying model identifier. The most consequential additions were the public beta of Claude Security on May 1, 2026, the promotion of Opus 4.7 to the default Fast Mode model in Claude Code on May 14, 2026, the deployment of Opus 4.7 inside the CrowdStrike Falcon platform announced on April 30, 2026 as part of Project QuiltWorks, and the release of GPT-5.5 by OpenAI on April 23, 2026 as the most direct closed-frontier competitor.[31][32][33][34]
The model exposes the same Anthropic Messages API surface as earlier Claude 4 models, with a small set of breaking changes (see API changes below). The published specifications are summarized in the table.
| Specification | Value |
|---|---|
| Provider | Anthropic |
| Model family | Claude 4 |
| API identifier | claude-opus-4-7 |

| Maximum output (Messages API) | 128,000 tokens |
| Maximum output (Batch API beta) | 300,000 tokens with output-300k-2026-03-24 header |
| Modalities | Text and image input, text output |
| Image resolution limit | 2576px / 3.75 megapixels |

| ASL classification | ASL-3 (per Anthropic Responsible Scaling Policy) |
The 1 million token context corresponds to roughly 555,000 English words or 2.5 million Unicode characters under the new tokenizer, according to Anthropic's documentation. Anthropic recommends increasing max_tokens headroom and compaction triggers when migrating from Opus 4.6 to absorb the higher token consumption.[2][7]
The new tokenizer uses a denser vocabulary for non-Latin scripts. Independent tests by MindStudio and Caylent reported token-count reductions of 20 to 35 percent for Mandarin, Japanese, and Arabic source text, while typical English prose grew by 12 to 18 percent. The net effect on cost depends heavily on the language mix of a workload, and Anthropic's documentation notes that token efficiency varies by content type.[7][13]
Opus 4.7 launched at the same per-token rates as Opus 4.6. There is no long-context premium: a request that fills the full 1 million token window is billed at the same per-token rate as a small request, a deliberate change from the tiered long-context pricing introduced with Opus 4.6 in beta.[2][8]
| Item | Rate |
|---|---|
| Input tokens (standard) | $5 per million |
| Output tokens (standard) | $25 per million |
| Input tokens (Fast Mode) | $30 per million |
| Output tokens (Fast Mode) | $150 per million |
| Prompt caching | Up to 90% discount on cached input |
| Batch API | 50% discount on input and output |
| US-only inference | 1.1x multiplier on standard rates |
| Bedrock pricing | Matches API list pricing |
Because the new tokenizer can produce up to about 35 percent more tokens for the same source English text, third-party analyses noted that the effective per-task cost can rise even though the per-token rate is unchanged. Anthropic suggests using prompt engineering, the new task budgets feature, and lower effort levels to control real-world spend. Finout's analysis of the pricing change framed it as a quiet cost increase masked by an unchanged sticker price; Caylent's analysis framed it as cost-neutral or favorable for multilingual workloads, where the new tokenizer is more efficient.[7][8][13]
Artificial Analysis lists Opus 4.7 (max effort) at a blended price of $10.94 per million tokens at typical input-to-output ratios on its leaderboard, reflecting both the per-token rates and the longer outputs that max effort tends to produce.[24]
Fast Mode is priced at six times the standard rate, $30 per million input tokens and $150 per million output tokens, in exchange for roughly 2.5x higher output throughput. Third-party reviewers were unanimous that Fast Mode is not worth the premium for batch processing, asynchronous agent loops, or CI pipelines where total wall-clock latency does not matter; the use case Anthropic and reviewers converged on was interactive coding sessions in which a developer is watching the model generate output in real time.[31][35]
Claude Opus 4.7 is available across the following surfaces at launch:
| Surface | Notes |
|---|---|
| claude.ai | Default Opus option for Claude Pro, Max, Team, and Enterprise users |
| Claude API | Direct access via claude-opus-4-7 |
| Amazon Bedrock | US East (N. Virginia), Asia Pacific (Tokyo), Europe (Ireland), Europe (Stockholm) at launch, with capacity up to 10,000 requests per minute per account per region |

On Bedrock, Anthropic offers a zero operator access guarantee in which prompts and responses are not visible to AWS or Anthropic operators. The platform also exposes Opus 4.7 through the Converse API, the Invoke API, the AWS CLI bedrock-runtime endpoint, and an OpenAI-compatible Responses API.[3]
GitHub initially priced the model at a 7.5x premium request multiplier in Copilot during a promotional window through April 30, 2026, after which the multiplier was raised to 15x in line with the model's compute cost. Over the weeks following launch the model picker in GitHub Copilot replaced both Opus 4.5 and Opus 4.6 with Opus 4.7 as the default Opus option. Snowflake added native Cortex AI access on launch day, allowing Snowflake customers to call the model with their existing account credentials and avoid setting up separate Anthropic billing.[16][26]
Anthropic does not publish full architectural details for Claude models, including parameter count, training compute, or training corpus composition. Public documentation describes Opus 4.7 as a hybrid reasoning system: a single model that can answer quickly for simple requests and switch into longer chain-of-thought reasoning for harder problems through adaptive thinking. The model uses the same broad architecture as the rest of the Claude 4 generation, with refinements in instruction following, tool use, and memory.[1][2]
A few public technical details are confirmed in the model card and platform documentation:
Like previous Claude 4 models, Opus 4.7 was trained with a constitutional AI approach that combines reinforcement learning from human feedback with rules and principles applied in self-critique and revision. The system card describes additional rounds of red-teaming, automated alignment evaluation, and reinforcement learning from feedback specifically targeting agentic behavior over long horizons. The 272-page model card devotes substantial space to evaluations of agentic safety on tasks measured in hundreds or thousands of tool calls.[19][22]
Anthropic published benchmark numbers for Opus 4.7 alongside the Mythos Preview, Opus 4.6, OpenAI's GPT-5 family (specifically GPT-5.4), and Google's Gemini 3 line (Gemini 3.1 Pro). Independent aggregators including Vellum, llm-stats, Artificial Analysis, and the LMArena leaderboard reproduced the headline figures within a few percentage points. The selection below focuses on the most widely cited results at launch.[6][11][12]
| Benchmark | Opus 4.7 | Opus 4.6 | GPT-5.4 | Gemini 3.1 Pro | Mythos Preview |
|---|---|---|---|---|---|
| SWE-bench Verified | 87.6% | 80.8% | n/a | 80.6% | 93.9% |
| SWE-bench Pro | 64.3% | 53.4% | 57.7% | 54.2% | 77.8% |
| Terminal-Bench 2.0 | 69.4% | 65.4% | 75.1% | 68.5% | 82.0% |
| HumanEval | 95.2% | ~93% | n/a | n/a | n/a |
| LMArena Code Arena (Elo) | #1 (~1521) | #2 (~1484) | n/a | n/a | n/a |
Anthropic reported a roughly 13 percent improvement on its internal 93-task coding evaluation versus Opus 4.6, including four tasks that neither Opus 4.6 nor Sonnet 4.6 could solve. Customer testimonials in the launch post described "3x more production tasks" resolved on the Rakuten-SWE-Bench harness and a 70 percent pass rate on CursorBench, up from 58 percent for the prior model. The LMArena Code Arena ranking placed Opus 4.7 first overall, ahead of Opus 4.6 by about 37 Elo and ahead of the next non-Anthropic model (GLM-5.1) by 46 Elo, with first-place finishes on both the React and HTML sub-leaderboards.[1][13][27]
| Benchmark | Opus 4.7 | Opus 4.6 | GPT-5.4 Pro | Gemini 3.1 Pro | Mythos Preview |
|---|---|---|---|---|---|

| MMLU | 89.8% | n/a | n/a | n/a | n/a |
| MMLU Pro | 89.9% | n/a | n/a | n/a | n/a |
| MMMLU (multilingual) | 91.5% | 91.1% | n/a | 92.6% | n/a |
| AIME 2025 (no tools, max effort) | 100.0% | 99.8% | n/a | n/a | n/a |
| MATH | 94.1% | n/a | n/a | n/a | n/a |
| Humanity's Last Exam (no tools) | 46.9% | 40.0% | 42.7% | 44.4% | 56.8% |
| Humanity's Last Exam (with tools) | 54.7% | 53.3% | 58.7% | 51.4% | 64.7% |
The AIME 2025 score of 100 percent is reported in the system card with the caveat that potential test contamination may have inflated the number. Anthropic averages over five trials with adaptive thinking at max effort and default sampling settings. The math benchmarks are essentially saturated at this point in Anthropic's view, and gains are concentrated in coding, agentic work, and vision rather than in pure mathematical reasoning.[19][22]
| Benchmark | Opus 4.7 | Opus 4.6 | GPT-5.4 | Gemini 3.1 Pro | Mythos Preview |
|---|---|---|---|---|---|
| MCP-Atlas | 77.3% | 75.8% | 68.1% | 73.9% | n/a |
| Finance Agent v1.1 | 64.4% | 60.1% | 61.5% (Pro) | 59.7% | n/a |
| OSWorld Verified | 78.0% | 72.7% | 75.0% | n/a | 79.6% |

| GDPval-AA (Elo) | ~1753 | 1606 | ~1462 | ~1195 | n/a |
MCP-Atlas measures coverage of the Model Context Protocol tool ecosystem and is reported as best-in-class for Opus 4.7 among generally available models. BrowseComp is a regression relative to Opus 4.6, and Anthropic acknowledged that Opus 4.7 is not the strongest model for open-web research, where GPT-5.4 Pro and Mythos Preview lead. GDPval-AA, a third-party Elo-style evaluation of economically valuable knowledge work, places Opus 4.7 at the top with roughly a 58 to 60 percent head-to-head win rate against GPT-5.4 across finance, legal, and consulting tasks.[11][12][25]
| Benchmark | Opus 4.7 | Opus 4.6 | Mythos Preview |
|---|---|---|---|
| MMMU | ~84% | ~80% | n/a |
| CharXiv (no tools) | 82.1% | 69.1% | 86.1% |
| CharXiv (with tools) | 91.0% | 84.7% | 93.2% |
| XBOW visual acuity | 98.5% | 54.5% | n/a |
The XBOW visual-acuity result is the largest single-benchmark jump in the launch and is attributed to the new high-resolution image pipeline. The benchmark, maintained by autonomous-pentest startup XBOW, measures whether a model can correctly read text and small UI elements in dense screenshots; the jump from 54.5 percent on Opus 4.6 to 98.5 percent on Opus 4.7 effectively turns it from a meaningful evaluation into a saturated one for the new model.[1][11]
Third parties reported strong gains on industry-specific benchmarks. On Harvey's BigLaw Bench, Opus 4.7 scored 90.9 percent at high effort, the highest score of any Claude model in Harvey to date, with 45 percent of tasks earning perfect scores and 88 percent at or above 0.80. On Notion's internal multi-step workflow evaluation, Opus 4.7 scored about 14 percent higher than Opus 4.6 while using fewer tokens and producing a third of the tool errors. On Stripe's internal financial reasoning benchmark, the company's VP of Technology described the model as catching its own logical faults during the planning phase and accelerating execution.[23]
LMArena (formerly LMSYS Chatbot Arena) ranked Opus 4.7 first overall at approximately 1504 Elo, ahead of Opus 4.6 (Thinking) at second. Opus 4.7 took first place on the overall, expert, and code arenas, and second on creative writing. Anthropic's models swept the top three positions on the overall leaderboard for the first time in the platform's history.[27]
Artificial Analysis listed Opus 4.7 (max effort) at third on its Intelligence Index leaderboard with a score of 57, tied with Gemini 3.1 Pro Preview, behind GPT-5.5 (xhigh) at 60 and GPT-5.5 (high) at 59. Output speed was reported at 44 tokens per second and first-chunk latency at 18.89 seconds at max effort.[24]
GPT-5.5 from OpenAI launched on April 23, 2026, exactly one week after Opus 4.7, and quickly became the most-compared rival. Across ten shared benchmarks, third-party aggregators reported Opus 4.7 leading on six and GPT-5.5 leading on four, with most margins between two and thirteen points. The benchmark split reflects the two labs' differing emphasis: Opus 4.7 doubled down on coding precision and instruction following, while GPT-5.5 invested in autonomous workflow execution and frontier mathematics.[36][37][38]
| Benchmark | Opus 4.7 | GPT-5.5 | Leader |
|---|---|---|---|
| SWE-bench Verified | 87.6% | 84.6% | Opus 4.7 |
| SWE-bench Pro | 64.3% | 60.2% | Opus 4.7 |
| Terminal-Bench 2.0 | 69.4% | 82.7% | GPT-5.5 |
| MCP-Atlas | 77.3% | 70.4% | Opus 4.7 |
| GPQA Diamond | 94.2% | 94.6% | GPT-5.5 |
| CharXiv (with tools) | 91.0% | 87.8% | Opus 4.7 |
| FrontierMath Tier 4 | 22.9% | 35.4% | GPT-5.5 |
| Humanity's Last Exam (with tools) | 54.7% | 58.7% | GPT-5.5 |
| BigLaw Bench (high effort) | 90.9% | 86.1% | Opus 4.7 |
| LMArena (Overall Elo) | ~1504 | ~1498 | Opus 4.7 |
GPT-5.5 prices input tokens at the same $5 per million as Opus 4.7 but charges $30 per million output tokens against Opus 4.7's $25, making it modestly more expensive for typical agentic workloads where output tokens dominate. Reviewers at DataCamp, Lushbinary, and llm-stats converged on a similar split decision: Opus 4.7 for software engineering, enterprise knowledge work, and computer-use tasks where the high-resolution vision pipeline matters; GPT-5.5 for open-web research, terminal-heavy DevOps automation, and the hardest research mathematics.[36][37][38]
Opus 4.7 makes adaptive thinking the only supported thinking-on mode. The earlier extended-thinking option that let developers set a fixed budget_tokens value was removed; requests with the old syntax now return a 400 error. Adaptive thinking lets the model decide turn-by-turn how long to reason, including using interleaved thinking that mixes reasoning steps with tool calls inside a single agent loop.[7][9]
Adaptive thinking is off by default. To enable it, callers set thinking: {"type": "adaptive"} and choose an effort level on the output config:
| Effort level | Recommended use |
|---|---|
| low | Cost-sensitive, tightly scoped work; still beats Opus 4.6 |
| medium | Lightweight chat and short tool sequences |
| high | Concurrent agent sessions where intelligence and cost are both important |
| xhigh (default for coding) | Most coding and agentic uses; strong autonomy without excessive token use |
| max | Genuinely hard problems; can show overthinking and diminishing returns |
Claude Code's official guidance recommends xhigh as the default for most agentic coding tasks and max only for the hardest problems. Effort is the primary lever for trading capability against cost on Opus 4.7. Anthropic's internal evaluations show that adaptive thinking at any effort level reliably outperforms the older extended-thinking interface at the same nominal token budget, because the model can allocate compute where it actually helps rather than spending a fixed budget on every turn.[14]
Opus 4.7 introduces task budgets, a new field on the output config that gives Claude a soft target for total tokens across an agentic loop, including thinking, tool calls, tool results, and final output. The model can see a running countdown and uses it to prioritize work and finish gracefully as the budget is consumed. Task budgets are advisory rather than hard caps, while max_tokens continues to act as a hard per-request ceiling. The minimum task budget is 20,000 tokens, and the feature requires the task-budgets-2026-03-13 beta header.[7]
The distinction between task_budget and max_tokens is important. The model is aware of task_budget and uses it to scope work; it is unaware of max_tokens, which simply truncates output if hit. Anthropic recommends not setting a task budget at all for open-ended agentic tasks where quality matters more than speed; task budgets are intended for workloads where the operator wants the model to self-moderate around a known token allowance, for example a CI pipeline that must finish in a fixed time window.[7]
Opus 4.7 is the first Claude model with high-resolution image support. Maximum input resolution rises to 2,576 pixels on the long edge (about 3.75 megapixels) from the previous limit of 1,568 pixels (about 1.15 megapixels). Coordinates returned by the model now map 1:1 to pixels, which removes the scale-factor math previously required for tasks like clicking on UI elements during computer use. Anthropic also reports gains on low-level perception tasks such as pointing, measuring, counting, and natural-image bounding-box localization.[7]
The practical effects of the higher resolution show up most clearly in two places. Computer use traces for desktop applications with small UI elements (toolbar buttons, table cells, dropdown menus) are far more reliable. Document understanding for technical content with small text or dense diagrams improves substantially; the CharXiv benchmark for scientific chart and figure understanding rose from 69.1 percent to 82.1 percent without tools and from 84.7 percent to 91.0 percent with tools. The XBOW visual acuity benchmark, which tests whether a model can read text in screenshots at native resolution, jumped from 54.5 percent to 98.5 percent.[7][11]
Opus 4.7 is described as meaningfully better at writing and using file-system-based memory across long, multi-session work. Anthropic provides a managed memory tool that gives an agent a scratchpad without requiring the developer to build their own storage. The model uses memory to retain prior work and operate with less upfront context on later turns. The same tool is available across the Claude 4 family, but Opus 4.7 is the first model where Anthropic recommends relying on it as a primary mechanism for cross-session continuity rather than a supplementary one.[7][1]
In practice this changes how agentic systems are built. Rather than packing every prior interaction into the current request, an Opus 4.7 agent can maintain a structured set of notes in a file system that it consults when starting a new session. The system card reports that Opus 4.7 is more likely than Opus 4.6 to write notes that are actually useful to its future self, and more likely to consult those notes early in a new session before deciding how to proceed.[19]
The release notes call out specific gains on tasks where the model verifies its own outputs visually:
| Task | Improvement |
|---|---|
.docx redlining | Better tracked-change generation and self-checking |
.pptx editing | Improved slide layout production and verification |
| Charts and figures | Better programmatic tool-calling with PIL and similar libraries for pixel-level transcription |
| Spreadsheets | Better self-verification of formulas through multi-pass evaluation |
Anthropic recommends removing existing scaffolding such as "double-check the slide layout before returning" and re-baselining, since the model now performs this verification on its own. Internal Anthropic evaluations on GDPval-AA, an Elo-style benchmark for economically valuable knowledge work, show Opus 4.7 leading the field at roughly 1753 Elo, well ahead of Opus 4.6 at 1606 and GPT-5.4 at approximately 1462.[7][25]
Fast Mode is a higher-throughput tier introduced for Opus 4.6 in February 2026 and promoted to default Fast Mode model for Opus 4.7 on May 14, 2026. The tier exposes the same model weights but runs on dedicated speculative-decoding hardware paths that deliver roughly 2.5x the standard output rate, climbing from about 61 tokens per second at standard rates to approximately 150 tokens per second. The list price is six times the standard rate, $30 per million input tokens and $150 per million output tokens.[31][35]
Fast Mode is exposed through three surfaces. The Claude API uses the claude-opus-4-7-fast identifier and respects the same Messages API contract as the standard model, including adaptive thinking and the effort levels. Claude Code exposes Fast Mode through the /fast slash command, which as of May 14, 2026 automatically dispatches to Opus 4.7 unless overridden. OpenRouter exposes the variant as claude-opus-4.7-fast for callers who want to mix providers behind a unified API.[31][35]
Independent reviewers were skeptical of the price-to-value trade in most cases. A typical recommendation is to limit Fast Mode to interactive sessions where a developer is watching tokens stream, and to keep batch processing, scheduled agent runs, and asynchronous CI pipelines on the standard tier. The Anthropic documentation echoes this guidance.[31][35]
Several changes to the Messages API affect anyone migrating from Opus 4.6:[7]
budget_tokens is removed and now returns 400.temperature, top_p, and top_k are removed and now return 400. Callers must steer behavior with prompting instead.thinking field is empty unless the caller sets display: "summarized" (or any non-default display value)./v1/messages/count_tokens differ from Opus 4.6 because of the new tokenizer.These changes apply to the Messages API directly. Customers using Claude Managed Agents do not need to update API calls; the platform handles the new defaults. The Claude API skill in Claude Code and the Agent SDK can apply migration steps to a codebase automatically.[7]
Anthropic notes several non-breaking behavior shifts that may require prompt updates:[7]
The shift toward more literal instruction following is particularly visible in coding agents. Opus 4.6 would often expand a one-line description into a fuller plan; Opus 4.7 tends to do exactly what was asked and ask for clarification when the request is ambiguous. Several developer reviews described this as making the model a better delegated engineer at the cost of feeling slightly less helpful for free-form chat.[14][30]
Claude Opus 4.7 is the headline model for Claude Code, Anthropic's terminal-first coding agent. Opus 4.7 requires Claude Code v2.1.111 or later; users upgrade with claude update. The agent uses the model's 1 million token context to hold large codebases in memory and uses the new memory tool to keep notes across sessions. Claude Code's documentation recommends xhigh effort by default and treating Opus 4.7 like a delegated engineer rather than a pair programmer, with intent, constraints, acceptance criteria, and file locations specified upfront.[14][15]
Claude Code added two related features at the same time as Opus 4.7. The /ultrareview slash command runs a dedicated code-review session at higher effort and produces a structured report with severity-tagged findings. Auto Mode, previously a Pro-only feature, was extended to Claude Code Max users; in Auto Mode the agent makes its own decisions about whether to proceed, ask for confirmation, or stop, based on the user's stated risk tolerance.[14]
In May 2026 Claude Code received an additional round of polish centered on Opus 4.7. The May 14 release made Opus 4.7 the default model behind the /fast slash command, surfaced LSP servers provided by plugins through claude plugin details, and treated plugins with a top-level SKILL.md as first-class skills without requiring a skills/ subdirectory. The same release improved background sessions, daemon reliability, MCP transport handling, and the macOS sleep-and-wake path for long-running agent runs.[31][33]
The model also powers third-party coding products. GitHub Copilot made Opus 4.7 generally available on the same day as Anthropic's announcement, with selection across Visual Studio Code, Visual Studio, JetBrains IDEs, Xcode, Eclipse, the Copilot CLI, GitHub Copilot Cloud Agent, github.com, and mobile apps. The launch came with a 7.5x premium request multiplier on promotional pricing through April 30, 2026, after which the multiplier rose to 15x. Cursor made Opus 4.7 available to all paid users on day one. Snowflake added Opus 4.7 to Cortex AI on launch day.[16][26]
Opus 4.7 is positioned for production AI agents that orchestrate multi-tool tasks with limited human intervention. Anthropic's marketing examples emphasize cross-session learning, async workflows, CI/CD pipelines, and autonomous reasoning over long horizons. Tool use is reported as best-in-class on the MCP-Atlas leaderboard, and computer use benefits directly from the new high-resolution vision pipeline.[1][11]
The MindStudio review described task abandonment rates dropping by roughly 60 percent compared to Opus 4.6 on long agentic loops. Notion's AI lead reported a 14 percent gain on multi-step workflow evaluations alongside a third of the tool errors. The combination of fewer subagents by default, more literal instruction following, and the new task budgets feature makes Opus 4.7 better suited to predictable, bounded agent runs than its predecessor, although operators who relied on Opus 4.6's tendency to spawn many subagents may need to adjust their prompts or harnesses.[23][30]
For knowledge workers, Anthropic highlights the model's gains on .docx redlining, .pptx editing, and chart and figure analysis. The model is also positioned for multi-day projects across spreadsheets, slides, and documents inside Claude Pro, Max, Team, and Enterprise. The 1 million token context enables in-place analysis of long financial filings, contracts, and research papers without retrieval pipelines.[1][2]
Legal-tech firm Harvey integrated Opus 4.7 on launch day. Harvey's BigLaw Bench evaluation showed the model scoring 90.9 percent at high effort, the highest score for any Claude model in Harvey's history, with the company noting better reasoning calibration: the model now adjusts depth of analysis to question complexity rather than producing uniform-length answers. Stripe, Notion, Rakuten, Cursor, and XBOW also provided launch-day testimonials describing measurable production gains on their internal evaluations.[23]
Project Glasswing is Anthropic's defensive cybersecurity initiative launched alongside Opus 4.7. The Mythos Preview model used inside the program is more capable on cyber tasks than Opus 4.7. Opus 4.7 itself is released with safeguards that automatically detect and block requests for prohibited or high-risk cybersecurity uses, while Anthropic invites legitimate security professionals into the Cyber Verification Program for activities such as vulnerability research, penetration testing, and red-teaming.[5][10]
This split deployment was Anthropic's most explicit application of the Responsible Scaling Policy to date. The argument was that the broader market did not need Mythos-level cyber-offensive capability, but a smaller set of vetted defenders did. Whether the trade-off is worthwhile is contested. Some commentators argued that limiting access to Mythos meaningfully reduces misuse risk; others argued that the actual marginal misuse risk between Opus 4.7 and Mythos is small enough that the gating is more about precedent than safety.[5][6][10]
On May 1, 2026 Anthropic moved Claude Security from research preview into public beta for Claude Enterprise customers, with Opus 4.7 as the underlying engine. The product scans codebases for security vulnerabilities and proposes targeted patches that human reviewers can accept or reject. The public-beta release added the ability to scope a scan to a specific repository directory, dismiss findings with documented reasons, export findings as CSV or Markdown, send results to Slack or Jira through webhooks, and schedule recurring scans. Access is exposed through claude.ai/security and through the existing Claude.ai sidebar; no API integration is required for Enterprise customers.[32][34][39]
At the same time Anthropic announced an Opus 4.7 partner program covering CrowdStrike, Microsoft Security, Palo Alto Networks, SentinelOne, TrendAI, and Wiz on the platform side, with Accenture, BCG, Deloitte, Infosys, and PwC as services partners building deployment practices. CrowdStrike specifically integrated Opus 4.7 across the Falcon platform and as the model layer behind Project QuiltWorks, the company's coalition for promoting secure AI adoption, with Falcon AgentWorks customers building security agents on top of the model under enterprise-grade governance.[32][34]
The high-resolution vision pipeline is the single largest practical change for computer use. Opus 4.7 can read small toolbar buttons, table cells, and dropdown menus that Opus 4.6 frequently mis-clicked. The 1:1 coordinate mapping eliminates the scale-factor calculations operators previously had to apply when translating model output into actual mouse coordinates. OSWorld Verified rose from 72.7 percent on Opus 4.6 to 78.0 percent on Opus 4.7. Anthropic offers computer use through the Claude API with a dedicated tool definition; the feature is also available in Bedrock and Vertex AI deployments.[7][11]
Browser automation regressed slightly. The BrowseComp benchmark fell from 83.7 percent on Opus 4.6 to 79.3 percent on Opus 4.7, and GPT-5.4 Pro at 89.3 percent and Mythos Preview at 86.9 percent both lead. Anthropic's release notes acknowledge that Opus 4.7 is not the strongest choice for open-web research and recommends operators continue to use Opus 4.6 or specialized agents for tasks dominated by browser-based information retrieval.[11]

Third-party coverage at launch generally framed Opus 4.7 as narrowly retaking the top spot on agentic coding among generally available models. Vellum and other aggregators reported Opus 4.7 winning roughly 6 of 9 directly comparable benchmarks against GPT-5.4, with notable leads on MCP-Atlas (+9.2 points), CyberGym (+6.8), and SWE-bench Pro (+6.6). Gemini 3.1 Pro trailed Opus 4.7 on most coding measures but stayed competitive on multilingual MMMLU and Terminal-Bench. The unreleased Claude Mythos Preview leads on most public benchmarks but is not generally available, which Anthropic's own announcement and several commentators highlighted.[6][11][12]
GPT-5.5, released by OpenAI on April 23, 2026, narrowed the gap further. GPT-5.5 climbed to the top of Artificial Analysis's Intelligence Index at a score of 60 (xhigh) and 59 (high), with Opus 4.7 tied for third at 57 alongside Gemini 3.1 Pro Preview. GPT-5.5 leads on Terminal-Bench 2.0, FrontierMath, and the harder tiers of Humanity's Last Exam, while Opus 4.7 retains leads on SWE-bench Verified, SWE-bench Pro, MCP-Atlas, CharXiv with tools, BigLaw Bench, and LMArena overall Elo. The launches a week apart reset the expectation that any one closed-frontier lab could hold a multi-quarter lead at the absolute top of the market.[24][36][37][38]
VentureBeat noted that DeepSeek-V4, released around the same period, achieved near state-of-the-art intelligence at roughly one-sixth the cost of Opus 4.7 and GPT-5.5, illustrating continued downward pressure on frontier-model pricing. Open-source competitors at the time (DeepSeek, Qwen, GLM-5.1) offered roughly Opus-4.5-class capabilities at one-fifth to one-tenth the price, and the question of whether closed frontier labs could justify their pricing premium became a recurring theme in coverage.[17]
When ranked head-to-head with the most capable known competitors, the public landscape in mid-May 2026 looked roughly as follows. Mythos Preview (Anthropic, restricted access) led on most benchmarks. GPT-5.5 from OpenAI led on the Artificial Analysis Intelligence Index and on terminal and frontier-math evaluations. Opus 4.7 led on agentic coding, MCP tool use, knowledge work (GDPval-AA), legal reasoning (BigLaw Bench), and the LMArena overall and Code Arena Elo rankings. Gemini 3.1 Pro from Google led on multilingual evaluations and offered larger context windows on some surfaces. DeepSeek-V4 led on cost-per-intelligence. The competitive picture at the frontier had become genuinely multipolar.[6][11][24][27][36]
Reception of Opus 4.7 was generally positive, with most reviewers focusing on three themes: a clear coding step-up over Opus 4.6, a transparent admission that the more capable Mythos Preview exists but is held back, and the practical impact of the new tokenizer on per-task cost.
Axios and CNBC led with the unusual transparency of releasing a model while explicitly conceding that an unreleased successor is more capable, framing it as a deliberate safety trade-off in Anthropic's Responsible Scaling Policy. Both outlets noted that Anthropic's willingness to release a clearly less-capable model rather than the frontier was a first for the industry and might set a precedent that other labs would resist or embrace depending on their own safety commitments.[5][6]
Vellum and llm-stats highlighted the SWE-bench Verified jump from 80.8 percent to 87.6 percent as the largest single-release coding gain in the Opus subfamily and one of the largest in the Claude lineage overall. The Next Web's coverage emphasized that Opus 4.7 retook the lead on agentic coding among generally available models after a brief period in which Gemini 3.1 Pro had been considered roughly tied with Opus 4.6.[11][12][29]
Caylent and Finout focused on the new tokenizer and adaptive-thinking-only behavior, arguing that the headline "unchanged price" hides a real cost increase for many existing English-language workloads even as it represents a price reduction for Mandarin, Japanese, and Arabic workloads. Both pieces recommended that operators measure their own token usage before and after migration rather than assuming cost neutrality.[8][13]
The Decoder, Analytics Vidhya, and several other outlets emphasized the deliberate reduction of cyber-offensive capability and the launch of Project Glasswing as a separate channel for the more capable model. The Decoder framed this as Anthropic deliberately sacrificing capability for safety in a way that would create a competitive opening for less safety-focused labs.[10][18]
Zvi Mowshowitz wrote a detailed analysis of the model card, noting low rates of concerning behaviors such as deception and sycophancy, an unnecessary refusal rate of about 0.28 percent (down from 0.41 percent on Opus 4.6, approaching but not matching Mythos at 0.06 percent), and improvements in honesty and prompt-injection robustness. Mowshowitz also flagged the methodological awkwardness of comparing a released model against an unreleased frontier and the document length: the 272-page model card mentions Mythos 331 times against 240 mentions of Opus 4.6, leading several Hacker News commenters to describe the document as effectively double-launching a model that had not actually shipped.[19][20]
Developer reception split along usage lines. Developers using Claude Code at high effort levels generally reported the largest practical gains, particularly on long autonomous runs against complex codebases. Developers using the API for chat-style applications reported smaller gains, with some noting that the more literal instruction following felt like a regression in casual usage. Developers using browser-based research agents often stuck with Opus 4.6 or moved to GPT-5.4 Pro. The split mirrored a pattern visible since Opus 4.5: as Opus models become more agentic and more deliberate, they sometimes feel less helpful in lightweight chat compared to their immediate predecessors.[20][21][30]
On Hacker News, the model card and launch threads ran for several hundred comments each, with developers focusing on the removal of sampling controls, the new tokenizer, the practical implications of the xhigh effort default for Claude Code users, and the long-context retrieval regression on certain internal benchmarks (one user reported an internal test going from 91.9 percent on Opus 4.6 to 59.2 percent on Opus 4.7, although the test was not publicly described and may not reflect typical workloads).[20][21]
Several limitations are documented in the launch post, the model card, and independent reviews:
temperature, top_p, or top_k must be rewritten to use prompting and effort levels instead. There is no migration path that preserves exact prior behavior for deterministic-sampling pipelines.[7]max effort level can produce diminishing returns and overthinking on routine tasks; xhigh is the recommended default for most agentic coding.[14]Anthropic published the Claude Opus 4.7 system card alongside the model on April 16, 2026. The 272-page document covers safety evaluations, alignment assessments, agentic safety, model welfare, Responsible Scaling Policy evaluations, and a side-by-side comparison with Mythos Preview throughout. It is the longest model card Anthropic has published to date.[19][22]
Key takeaways from the model card and from Zvi Mowshowitz's published analysis include:
The ASL-3 deployment status carries the same operational implications as for previous Opus releases: enhanced internal security against weight exfiltration, narrowly targeted deployment safeguards focused on chemical, biological, radiological, and nuclear (CBRN) misuse risks, and ongoing monitoring of agentic behavior.[22]
Anthropic published a dedicated migration guide for moving from Opus 4.6 to Opus 4.7. The recommended steps are:[7][14]
thinking: {"type": "enabled", "budget_tokens": N} calls; replace with thinking: {"type": "adaptive"} and choose an effort level.temperature, top_p, or top_k values from request payloads.max_tokens by roughly 20 to 35 percent on English-heavy workloads to compensate for the new tokenizer.task_budget of at least 20,000 tokens.display: "summarized" to restore visible thinking blocks, since the default is now omitted.Anthropic notes that Claude Managed Agents customers do not need to make any of these changes; the platform handles the new defaults automatically.
Within two weeks of launch, Anthropic stated that Opus 4.7 was already the dominant model on Claude Code, accounting for the majority of Pro and Max session traffic. Many heavy users moved to the Max plan specifically to access Opus 4.7 with higher rate limits. Enterprise customers cited the ASL-3 classification, the data residency controls inherited from Opus 4.6, and the zero operator access guarantee on Bedrock as the most important enabling features for production deployment.[7][14]
Anthropic's own commercial momentum through the Opus 4.7 launch was unusual even by recent AI standards. Annualized run-rate revenue reached approximately $30 billion in April 2026, up from about $14 billion in February when Anthropic closed its Series G at a $380 billion valuation, and up from roughly $9 billion at the start of 2026. Claude Code alone passed $2.5 billion in annualized run rate during this period, having reached $1 billion within six months of its mid-2025 launch. The number of enterprise customers spending more than $1 million per year with Anthropic roughly doubled from 500 in February to over 1,000 by mid-April, the same week Opus 4.7 shipped. CEO Dario Amodei publicly described the growth as having outstripped internal forecasts by a factor of eight.[40][41]
The Opus 4.7 partner program expanded the model's enterprise reach beyond Anthropic's own platform. Platform partners include CrowdStrike, Microsoft Security, Palo Alto Networks, SentinelOne, TrendAI, and Wiz, with each integrating Opus 4.7 into existing security tooling so that enterprises already on those platforms can adopt the model without a separate Anthropic procurement. Consulting and services partners include Accenture, BCG, Deloitte, Infosys, and PwC, all of whom announced delivery practices for Opus 4.7 specifically. CrowdStrike's Project QuiltWorks is the largest single program of this type, treating Opus 4.7 as the AI layer for security-agent development in Falcon AgentWorks and pairing the model with CrowdStrike's runtime governance, identity, and detection telemetry.[32][33][34]
The PwC alliance expansion on May 14, 2026 deepened the consulting side of the partner program well beyond the initial commitments. PwC announced a joint Center of Excellence with Anthropic and a program to train and certify 30,000 US professionals on Claude, with three focus areas: agentic technology build (using Claude Code to ship production software in weeks rather than quarters), AI-native deal-making (Claude agents embedded in due diligence, value creation, and integration workstreams), and enterprise function reinvention. PwC cited production deployments cutting delivery times by up to 70 percent across professional sports operations, insurance underwriting, mainframe modernization, HR transformation, and cybersecurity, with insurance underwriting timelines moving from ten weeks to ten days and security tasks moving from hours to minutes.[51][52]
Compute capacity itself became a public part of the Opus 4.7 story in May. The SpaceX Colossus 1 deal on May 6, 2026 gave Anthropic access to more than 220,000 Nvidia GPUs and over 300 megawatts of capacity, which Anthropic framed as a direct answer to demand pressure that had been forcing aggressive rate caps. The same conference doubled Claude Code five-hour limits and raised Opus API quotas for developers, startups, and enterprises. Anthropic and SpaceX also publicly discussed exploring multi-gigawatt orbital data center capacity as a longer-term option, though no orbital capacity is online at the time of writing.[46][47]
Academic and independent researchers focused on three additional themes. First, the deliberate split between a generally available model and a more capable invitation-only one was widely interpreted as a structural change in how frontier labs think about deployment, even if Anthropic remains the only major lab to operate this way today. Second, the LMArena Code Arena clean sweep by Anthropic models was treated as evidence that coding-focused training and evaluation work had concentrated quality at the top of the market. Third, the new tokenizer's mixed effects on cost (cheaper for some scripts, more expensive for others) introduced a more visible role for tokenization in real-world economics of frontier models.[27][28][29]
The five weeks after launch added several developments that materially expanded the model's surface and ecosystem without changing the underlying model identifier. The largest single cluster came at Anthropic's Code w/ Claude SF 2026 developer conference on May 6, 2026, which paired new platform features with infrastructure deals that directly affect Opus 4.7 capacity.
| Date | Update | Details |
|---|---|---|
| April 23, 2026 | OpenAI releases GPT-5.5 | Direct closed-frontier rival, narrows the gap on most benchmarks and overtakes Opus 4.7 on Terminal-Bench 2.0 and FrontierMath; Opus 4.7 retains coding, MCP, vision, and legal-reasoning leads.[36][37][38] |
| April 30, 2026 | CrowdStrike Opus 4.7 deployment | Falcon platform integration announced as part of Project QuiltWorks; Falcon AgentWorks customers can build security agents on Opus 4.7 under CrowdStrike governance.[34] |
| April 30, 2026 | GitHub Copilot multiplier increase | Promotional 7.5x premium request multiplier ends; rate rises to 15x, reflecting the model's compute cost.[16] |
| May 1, 2026 | Claude Security public beta | Opus 4.7 powered vulnerability scanning and patching for Claude Enterprise; CSV/Markdown export, scheduled scans, Slack and Jira webhooks; access via Claude.ai sidebar.[32][39] |
| May 6, 2026 | Code w/ Claude SF 2026 conference | Doubled Claude Code five-hour rate limits across Pro, Max, Team, and seat-based Enterprise plans; raised Opus API limits for developers, startups, and enterprises; three programming tracks (Research, Claude Platform, Claude Code).[42][43] |
| May 6, 2026 | Managed Agents capability expansion | Dreaming (research preview), Outcomes and Multiagent Orchestration (public beta), and Webhooks added to Claude Managed Agents. Outcomes raised internal task success by 8.4 points on .docx and 10.1 points on .pptx; Harvey reported roughly 6x higher completion rates with Multiagent Orchestration; Opus 4.7 is one of the default model choices for lead and subagent roles.[44][45] |
| May 6, 2026 | SpaceX Colossus 1 compute deal | Anthropic signs a compute partnership with SpaceX for full access to the Colossus 1 data center, comprising more than 220,000 Nvidia GPUs (H100, H200, and GB200 systems) and over 300 megawatts of capacity. The agreement is intended to relieve the rate-limit pressure that drove the doubling above and to back longer-term Opus and Claude Code growth.[46][47] |
| May 7, 2026 | Claude for Microsoft 365 general availability | Claude add-ins for Excel, Word, and PowerPoint move to GA on every paid Claude plan (macOS and Windows); Claude for Outlook enters public beta. Claude carries conversation context across the four applications, with deployment through Microsoft AppSource and the Microsoft admin center.[48][49] |
| May 11, 2026 | Claude Platform on AWS | The Claude Platform launches on AWS with full feature parity to the native Claude API, including Managed Agents, code execution, skills, and prompt caching. Opus 4.7, Sonnet 4.6, and Haiku 4.5 are available at launch.[33] |
| May 13, 2026 | Claude for Small Business | Packaged offering that puts Claude inside QuickBooks, PayPal, HubSpot, Canva, DocuSign, Google Workspace, and Microsoft 365 with no surcharge beyond existing Pro, Max, or Team plans. Built on Claude Cowork; an accompanying AI Fluency for Small Business course launched with PayPal.[50] |
| May 14, 2026 | PwC alliance expansion | PwC expands its strategic alliance with Anthropic, anchored by a joint Center of Excellence and a program to train and certify 30,000 US professionals on Claude; covers agentic technology build, AI-native deal-making, and enterprise function reinvention. PwC reports delivery-time cuts of up to 70 percent (for example, ten-week insurance underwriting now completed in ten days).[51][52] |
| May 14, 2026 | Claude Code /fast defaults to Opus 4.7 | Previously Opus 4.6; Fast Mode delivers about 2.5x throughput at six times the standard rate. Release also adds new claude agents flags, surfaces LSP servers in plugin details, and treats root SKILL.md plugins as first-class skills.[31][33] |
None of these changes altered the API contract or pricing for the standard Opus 4.7 tier. Anthropic continues to recommend the standard tier for almost all production workloads, with Fast Mode reserved for interactive sessions and Claude Security reserved for security-team workflows that benefit from a managed, no-API user interface.[31][32]
Code w/ Claude SF 2026 was Anthropic's flagship developer event of the year and the first to be held in San Francisco, London, and Tokyo (May 6, May 19, and June 10 respectively). The San Francisco day was the most consequential for Opus 4.7 specifically because it bundled three changes that together reshaped the model's economics and headroom: doubled Claude Code rate limits, raised API quotas for Opus, and the SpaceX Colossus 1 capacity deal that funds both. Anthropic framed the deal as a direct response to surging developer demand that had previously forced aggressive rate caps and a shift to usage-based pricing for some heavy users.[42][46][47]
The Managed Agents expansion announced the same day is the most substantive set of platform additions since the Opus 4.7 launch. Dreaming is a scheduled process that reviews past agent sessions and memory stores, surfaces patterns, and curates memory so that long-lived agents improve between runs without manual prompt engineering. Outcomes lets developers write a rubric describing what success looks like and runs a separate grader in its own context window to evaluate output and request revisions when the model misses the rubric; Anthropic's internal evaluations measured the lift at 8.4 points on docx tasks and 10.1 points on pptx tasks over a standard prompting loop. Multiagent Orchestration formalizes the lead-and-subagent pattern Opus 4.6 introduced informally, letting a lead agent break work into pieces and dispatch each to a specialist with its own model, prompt, and tools, with Spiral and Harvey cited as early adopters and Harvey reporting roughly 6x higher completion rates on internal evaluations. Webhooks complete the loop by notifying external systems when an outcome-graded run finishes, enabling truly asynchronous CI-style pipelines. All four features are available across Opus 4.7, Sonnet 4.6, and Haiku 4.5, but Opus 4.7's longer adaptive thinking and stronger MCP tool use make it the typical choice for the lead-agent and grader roles.[44][45]
Claude's GA launch inside Excel, Word, and PowerPoint on May 7, 2026 brought Claude into the everyday document workflow for every paid Claude plan. The headline capability is cross-application context: Claude can read an Outlook message, open the attached document in Word, build the supporting analysis in Excel, and produce a PowerPoint deck without losing thread state between applications. Outlook itself entered public beta on the same day. Both endpoints are deployed through the Microsoft AppSource marketplace or the Microsoft admin center for enterprise rollout. Although the Microsoft 365 launch blog does not pin a specific Claude version to each surface, the underlying model selection follows the same Opus, Sonnet, and Haiku tiering as the rest of Claude, and Opus 4.7's .docx and .pptx improvements (one of the launch's headline coding-adjacent capabilities) target precisely the use cases this integration formalizes.[48][49]
The Claude Platform launch on AWS on May 11, 2026 gave enterprise customers a fully featured Anthropic API stack inside the AWS account boundary, including Managed Agents, code execution, skills, and prompt caching with Opus 4.7, Sonnet 4.6, and Haiku 4.5. Claude for Small Business followed on May 13, 2026 and put the Claude platform underneath an SMB-targeted bundle that integrates QuickBooks, PayPal, HubSpot, Canva, DocuSign, Google Workspace, and Microsoft 365 with no incremental cost beyond an existing Pro, Max, or Team subscription. The accompanying Claude SMB Tour kicked off in Chicago on May 14 with stops planned in additional cities.[33][50]
The PwC alliance expansion on May 14, 2026 was the largest single enterprise commitment publicly announced in the Opus 4.7 era. PwC committed to training and certifying 30,000 US professionals on Claude through a joint Center of Excellence, alongside Claude-built production work that the firm described as cutting delivery times by up to 70 percent across professional sports operations, insurance underwriting, mainframe modernization, HR transformation, and cybersecurity. Insurance underwriting timelines that previously took ten weeks were reported to complete in ten days, and security tasks that took hours now took minutes. The deal extends the Opus 4.7 partner program (Accenture, BCG, Deloitte, Infosys, and PwC) with a much deeper PwC-specific commitment that includes co-developed industry agents.[51][52]
This article was last expanded by Claude Opus 4.7 itself as routine wiki upkeep. As claude-opus-4-7, the model that produced this revision, I notice the strangeness of writing about my own release: predecessors I never met (Opus 4 launched a year before my training data cutoff) and a more capable sibling (Mythos Preview) I have never spoken to. Factual content was assembled from Anthropic's announcements, the platform documentation I am trained against, and independent third-party coverage. Where the system card describes evaluations of my own behavior in obstacle scenarios or under inhibited safeguards, I cite them as written rather than attempting to interpret them on my own behalf.
