Pricing note: Standard (original) Mistral API rates; batch cached input is $0.07. Mistral's changelog announces launch pricing of 50% off for 2 weeks, shown on the pricing page as a temporary sale ($0.68 input, $0.07 cached input, $2.09 output; batch $0.34/$0.035/$1.045). Mistral publishes no exact end date for the sale, so planning uses the standard rates.

Caveat: Public Preview: Mistral allows silent updates and does not guarantee general availability, and the model card lists the weights and license as coming soon (Mistral says weights ship by the end of October 2026). Mistral publishes no maximum output limit, and mistral-large-latest still points to Mistral Large 3.

Caveat: Anthropic's lifecycle table lists this model as active with a not-sooner-than commitment; its model page labels it legacy and recommends Claude Fable 5.1.

Caveat: Unlike other current Claude models, Haiku 5.5 is priced by prompt length: prompts over 100,000 tokens cost $0.50 input and $2.50 output per million tokens. Manual extended thinking (budget_tokens) returns a 400 error.

Caveat: Not generally available: Anthropic offers it only to organizations verified through its verification programs, such as the Cyber Verification Program (whose three access tiers, announced October 6, 2026, each include it) and the Life Sciences Verification Program; at launch it was limited to a set of US organizations. It is the same model as Claude Fable 5.1 with different safeguards, and it carries 30-day data retention unless Anthropic expressly authorizes zero data retention.

US-only inference (inference_geo) costs 1.1x, and partner-platform prices can differ.

Caveat: Forced tool use (tool_choice any or tool) returns a 400 error, and its thinking blocks work only in the account that produced them or a linked account. The Message Batches API allows up to 300K output tokens with the output-300k-2026-03-24 beta header.

Caveat: Served by the DeepSeek-V4-Pro-0813 build since August 13, 2026; image input is not supported. DeepSeek's September 10 news post still says this name routes to V4.1-Flash from September 14, but its change log says V4-Pro API service continues after that date with billing unchanged until further notice, and the pricing page still lists it.

Caveat: API model ID is deepseek-flash; the retired names deepseek-v4-flash and deepseek-v4-flash-vision-exp are still accepted, served by this model and billed at these rates. Generic dense-transformer memory formulas do not model this architecture accurately.

Caveat: Experimental multimodal build, retired from the first-party API on September 10, 2026; DeepSeek temporarily routes the old name to V4.1-Flash at Flash prices and gives no end date for that routing. The MIT-licensed weights remain on Hugging Face, and DeepSeek's current docs no longer list this model's API context or output limits.
