"GPTs created by the ChatGPT team." Official builder description on the GPT Store
Custom GPTs by ChatGPT are the small set of Custom GPTs that OpenAI itself publishes under the verified @ChatGPT builder profile inside the GPT Store. They shipped alongside the launch of GPTs at DevDay on November 6, 2023, and were the first concrete examples of what a custom version of ChatGPT could look like. Most of them are short, single-purpose assistants built on the same GPT-4 base that powered ChatGPT Plus at the time, with one or two tools enabled (web browsing, DALL-E image generation, or Python data analysis) and a tight system prompt. They were never the most technically interesting GPTs in the store, but because they sit on the @ChatGPT profile and turn up first in the official Explore GPTs view at chatgpt.com/gpts, they are the GPTs most users have actually opened.
When OpenAI introduced GPTs in November 2023, it needed a way to show non-developers what "a tailored version of ChatGPT" actually meant. The answer was a row of in-house GPTs published under the @ChatGPT builder name. They covered three things at once: image generation through DALL-E 3, Python-based data analysis, and short prompt-only assistants for everyday tasks like recipes, laundry, and explaining board game rules.
Unlike third-party GPTs in the GPT Store, the @ChatGPT GPTs are not built by verified builders from external companies. They appear with a small "By ChatGPT" attribution on their cards instead of a builder website. They are also the GPTs OpenAI tends to feature in onboarding, in the DALL-E and Lifestyle categories on the store, and in marketing screenshots about what GPTs can do.
A few facts worth knowing up front:
On November 6, 2023, Sam Altman opened OpenAI's first DevDay conference in San Francisco by announcing GPTs, calling them "the number-one developer request." Altman demonstrated the GPT Builder by typing a few sentences into a chat window and watching ChatGPT spin up a startup-mentor GPT in front of the audience. The same keynote announced GPT-4 Turbo, the Assistants API, and the future GPT Store.
At the end of the keynote OpenAI quietly published its own GPTs to the Explore page. The November 8, 2023 rollout to ChatGPT Enterprise customers brought GPTs to that tier, and by late November ChatGPT Plus subscribers worldwide could open them through the sidebar.
The GPT Store opened on January 10, 2024, after slipping its original late-November target during the brief firing and rehiring of Sam Altman. At launch the store had categories for DALL-E, Writing, Productivity, Research and Analysis, Programming, Education, and Lifestyle. Each category surfaced two kinds of GPTs: featured third-party builds (AllTrails, Consensus, Khan Academy Code Tutor, Canva), and the @ChatGPT in-house GPTs.
The @ChatGPT collection at that point included roughly sixteen GPTs. Most of them had been live since DevDay; a handful were added in the weeks before the store opened so each category had at least one OpenAI-built example.
OpenAI never published a full changelog for the @ChatGPT GPTs, so the only way to see them go away is by visiting their old /g/g-... URLs. The browsing-only GPT effectively stopped being interesting after ChatGPT gained native real-time browsing in 2024. The DALL-E GPT itself was rebuilt in March 2025 when GPT Image 1 replaced DALL-E 3 as the underlying image model.
The table below lists the GPTs that have appeared under the @ChatGPT builder profile since November 2023. Functions are based on the GPT cards in the store and on the GPTs' visible behavior; launch context refers to whether the GPT was part of the original DevDay batch or added before the GPT Store opened on January 10, 2024.

Fifteen or so of these were the GPTs featured most heavily on the store's home page during the first half of 2024.
The DALL-E GPT (/g/g-2fkFE8rbu-dall-e) is the most visible GPT on the store. It is also one of the few @ChatGPT GPTs whose underlying model has changed.
At launch in November 2023, the DALL-E GPT was a thin wrapper around DALL-E 3, which had been rolled into ChatGPT Plus and Enterprise in October 2023. The system prompt rewrote the user's input into a richer DALL-E prompt and called the image tool. On March 25, 2025, OpenAI shipped GPT Image 1 (then unnamed and marketed as "4o image generation") as the new default image model in ChatGPT, and the DALL-E GPT silently switched over to it. The card still says "DALL-E" because that is the brand users recognize, but the model behind it is autoregressive GPT Image 1, not the diffusion-based DALL-E 3 it shipped with.
The DALL-E GPT card also lives in the DALL-E category of the store, which is named after this GPT rather than the model. Cosmic Dream, Coloring Book Hero, Hot Mods, and Sticker Whiz also live in that category and use the same underlying image stack.
Data Analyst is the most quietly important @ChatGPT GPT, because it is the public face of the Python sandbox that has been quietly running inside ChatGPT for years. The lineage:
In practice the GPT does what data analysts use the underlying tool for: read a CSV or Excel file, ask follow-up questions about the columns, run pandas operations, produce a chart, and save the cleaned file back to the user. The GPT card is also where most non-developers first encounter the fact that ChatGPT can run arbitrary Python in a Linux container.
ChatGPT Classic is the GPT for users who want plain GPT-4 with nothing else turned on. It was useful in late 2023 and early 2024 because the default ChatGPT experience had started auto-routing to DALL-E, browsing, and the Python sandbox depending on what the prompt looked like; ChatGPT Classic disabled all of that so the model behaved like the original chat.openai.com from March 2023. After OpenAI consolidated everything into the model picker, the GPT became less essential, but it is still online at /g/g-YyyyMT9XH-chatgpt-classic.
A cluster of @ChatGPT GPTs share the same shape: a one-paragraph system prompt, browsing on, DALL-E on, and a domain framing.
None of these GPTs is technically interesting on its own. The point is that the @ChatGPT profile owns at least one example in each of the lifestyle subdomains where third-party GPT builders were expected to compete.
Three of the original @ChatGPT GPTs are role-play assistants in disguise.
Game Time is the most-loved of the three. It asks for the name of a board game, looks up the rules with browsing if needed, and walks users through setup and a first turn. Game journalists who tested it in late 2023 found it competent on well-documented games like Catan and Wingspan, and less so on niche or recently released titles where rules text was not yet on the open web.
The Negotiator role-plays a counterparty in a salary, real estate, or used-car negotiation. The system prompt explicitly references BATNA (Best Alternative to a Negotiated Agreement), which is the framework taught in the standard Getting to Yes literature. The GPT will not give advice for what it considers unethical or coercive negotiation.
Creative Writing Coach is the editor-facing version: paste in a short story or chapter, and the GPT returns feedback on character, pacing, and dialogue. Writer-facing publications like Jane Friedman tested it in 2024 and concluded that, while its feedback was generic, it was a useful first reader for a single revision pass.
These four are all DALL-E-driven and share a system prompt skeleton: take a user idea, rewrite it as a DALL-E prompt in a specific style, generate, and return.
The most consequential change to the @ChatGPT lineup was not the addition of a new GPT but the swap of the model behind an existing one. On March 25, 2025, OpenAI launched what it then called "4o image generation" inside ChatGPT, and on April 23, 2025, it released the same model to developers via the API as gpt-image-1. The model is autoregressive rather than diffusion-based, follows long instructions far more reliably than DALL-E 3, and natively supports image-to-image editing and rendering of legible text.
The DALL-E GPT was migrated to this new backend without changing its name or its card. The category page on the GPT Store is also still called DALL-E. The practical effect is that any user who opens the DALL-E GPT today is calling GPT Image 1 under the hood, not the original DALL-E 3 model the GPT was built on. The same is true of Coloring Book Hero, Cosmic Dream, Sticker Whiz, Sous Chef, and the other @ChatGPT GPTs that internally call the image tool.
The Studio Ghibli style trend that briefly dominated social feeds in late March 2025 was produced almost entirely through this updated DALL-E GPT and through the same image tool inside the main ChatGPT interface.
The history of the Data Analyst GPT is the history of OpenAI's Python sandbox under three names:
| Period | Name | Where it ran |
|---|---|---|
| March 2023 to July 2023 | Code Interpreter (alpha plugin) | ChatGPT Plus plugin slot |
| July 2023 to August 2023 | Code Interpreter (GA) | Built-in ChatGPT Plus mode |
| August 2023 to November 2023 | Advanced Data Analysis | Built-in ChatGPT Plus and Enterprise mode |
| November 2023 onward | Data Analyst (also still Advanced Data Analysis) | @ChatGPT GPT and built-in mode |
The August 2023 rename to Advanced Data Analysis was widely reported by VentureBeat, Pluralsight, and others as a marketing move tied to the launch of ChatGPT Enterprise; the underlying sandbox did not change. When the GPT framework launched, the same sandbox was wrapped as the Data Analyst GPT with a tighter system prompt about producing summaries, charts, and cleaned files.
The sandbox itself is a Linux container with Python, pandas, NumPy, matplotlib, scikit-learn, and a long list of other libraries preinstalled. Files uploaded by the user are mounted into the container, the model writes Python that runs inside it, and the model can read both stdout/stderr and the rendered chart back into the conversation. The container is ephemeral; it resets between sessions.
The @ChatGPT collection is smaller in 2026 than it was at launch. Two patterns explain most of the missing GPTs.
Before GPTs existed, ChatGPT had a separate Browse with Bing mode, originally rolled out in May 2023 and disabled on July 3, 2023, after researchers showed it could be used to bypass paywalls and surface private content. When browsing came back later in 2023, it briefly appeared as an @ChatGPT "Web Browser" GPT in the early Explore page. That GPT effectively became redundant when ChatGPT shipped real-time web search as a default capability in late 2024, and the standalone Web Browser GPT was removed.
The Tech Support Advisor and Math Mentor GPTs, which both internally relied on browsing, kept the browsing tool but lost much of their special status once browsing became default for all users.
Hot Mods was always a clumsy GPT, because DALL-E 3 did not really do image-to-image editing; the GPT mostly used the uploaded image as a description target and then generated a fresh image. After GPT Image 1 shipped native image editing in March 2025, the use case effectively moved into the main ChatGPT interface, and Hot Mods became a niche shortcut rather than a primary entry point.
The @ChatGPT GPTs sit uncomfortably alongside the third-party ecosystem in the GPT Store.
Where third-party GPTs aim to be products, the @ChatGPT GPTs read more like the in-house demo screens that ship with a new operating system: less ambitious, more polished, and almost always retired or absorbed once the platform underneath them grows up.
