LLM Changelog

What
: While moving over the information about the default file size limits of
Google's crawlers and fetchers to the
crawler documentation
,
we also updated the
Googlebot documentation
about its own file size limits.
Why
: The original location of the default file size limits was not the most logical
place as it applies to all of Google's crawlers and fetchers, and the move enabled us to
be more precise about Googlebot's limits.

Today we’re releasing the Codex app for MacOS,  a command center for managing multiple coding agents in parallel. The app lets you run long‑horizon and background tasks, review clean diffs from isolated worktrees, see agent progress and decisions, and execute reusable skills and automations.
Available with ChatGPT plans that include Codex, with a limited‑time promo: Free and Go can try Codex with included limits, while Plus, and Pro users get 2x Codex rate limits.
Get started by downloading the macOS app, andlearn moreabout Codex.

What
: Updated the
structured data carousels (beta)
documentation and the
South African badges and refinement chips blog post
to include additional query types.
Why
: The South African carousel, badges, and refinement chips now support queries
related to food delivery, car hire, and bus booking.

We're rolling out an age prediction model on ChatGPT consumer plans to help determine whether an account likely belongs to someone under 18, so we can apply the right experience and safeguards for teens.The model looks at a combination of behavioral and account-level signals, including how long an account has existed, typical times of day when someone is active, usage patterns over time, and a user’s stated age.If an adult is placed in the under-18 experience by mistake, they can quickly verify their age with a selfie through Persona, a verification service available in Settings > Account. Users can check whether safeguards have been added and verify at any time.

We’re starting to roll outHealth, a dedicated space in ChatGPT for health and wellness conversations. You can securely connect medical records, Apple Health and supported wellness apps so answers can be grounded in your own data. Health is designed to help you navigate medical care, not replace it. Health conversations, memory, and files are kept separate from the rest of ChatGPT and are not used to train our foundation models.
Health appears as a new space in the ChatGPT sidebar. If you ask a health-related question in a regular chat, ChatGPT may also suggest continuing in Health. If you’re interested in getting access as it becomes available, you can sign up for thewaitlist. We’re starting by providing access to a small group of early users to learn and continue refining the experience. At launch, Health is available onweb and iOS, with Android coming soon toChatGPT Free, Go, Plus, and Pro usersin supported countries (excluding the EEA, Switzerland, and the UK).
Learn more in theblogorhelp center article.

Today we’re rolling outYour Year with ChatGPT, an optional, personalized end-of-year experience that reflects on how you interacted with ChatGPT in 2025. It highlights high-level themes from your conversations and includes summary statistics about your usage over the year.
This experience is rolling out gradually throughout the day, so it may not be available to everyone immediately. It’s available to Free, Plus, and Pro users in United States, United Kingdom, Canada, Australia, and New Zealand as well as Go, Plus, and Pro users in India, and is not available on Business, Enterprise, or Edu plans.
To seeYour Year with ChatGPT, Memory and Reference Chat History must be turned on, and you must meet a minimum activity threshold. If you have very limited activity, you’ll only see basic chat statistics.
At launch, this experience is available in English in the United States, United Kingdom, Canada, Australia, and New Zealand.

In addition to selecting a base style and tone preset—like candid and friendly—you can now adjust specific characteristics individually.  From the ‘personalization’ pane in settings, you can adjust ChatGPT to:
Be more or less warmBe more or less enthusiasticUse more or fewer headers & listsUse more or fewer emojis

You can now browse and add approved apps in the newapp directory. Apps let you work with your tools and data directly inside a conversation—from interactive in-chat experiences to secure connections that allow ChatGPT to search and reference information from third-party services.As part of this update,connectors now appear in the directory as apps, making it easier to manage all your tools in one place. References across the Help Center have been updated to reflect this new terminology.Apps are available to all logged-in ChatGPT users, with availability and functionality varying by plan and region. Some apps or capabilities may not be available in certain regions or may require specific plan tiers.Additionally,developers can submit apps for review and publicationin the app directory, making approved apps available to a broader set of ChatGPT users.

Today, we’re releasingGPT-5.2, the next upgrade to the GPT-5 series. GPT-5.2 is smarter and more useful for both work and learning—while remaining just as enjoyable to talk to. As with GPT-5.1, we’re continuing to improve our main models for everyone on a regular basis to make them more useful and enjoyable to use.GPT-5.2 Instantis a fast yet powerful workhorse for everyday work and learning, with clear improvements in info-seeking questions, how-tos and walk-throughs, technical writing, and translation, all while retaining the warmer, more conversational tone introduced in GPT-5.1 Instant. Early testers noted its more clearly structured explanations where important info is highlighted upfront. It’s also more effective at supporting studying and skill-building, as well as offering clearer job and career guidance.GPT-5.2 Thinkingsolves harder work tasks more effectively and with more polish—particularly in spreadsheet formatting and financial modeling, alongside improvements in slideshow creation. Early testing showed gains in coding, summarizing long documents, answering questions about uploaded files, walking through complex math and logic step by step, and helping with planning and decision-making with clearer structure and thoughtful detail.GPT-5.2 Prois our smartest and most trustworthy model yet for difficult questions where a higher-quality answer is worth the wait. In early testing, it shows fewer major errors and stronger performance across complex domains like programming.All three models (Instant, Thinking, and Pro) have a new knowledge cutoff of August 2025. For users, this means GPT-5.2 starts with a more current understanding of the world, so answers are more accurate and useful, with more relevant examples and context, even before turning to web search.Read ourblogfor more details on examples and evals.Update for free and Go users:We’re removing automatic model switching for reasoning in ChatGPT. Previously, some questions were automatically routed to

We’re making ChatGPT Voice a seamless part of the ChatGPT experience, so you can use voice right inside the chat interface you already use every day—no separate mode required.
Many of you have asked for a more flexible Voice experience—now, you can speak, listen, and see your conversation at the same time. Answers will be spoken alongside streamed text, image search results, widgets (maps, weather, etc.) and more—right in the same chat thread.
This makes voice chats clearer, richer and more contextual by pairing spoken answers with visual context. You can:
Follow along with typed answers as you listenSee visual search results like images, charts, and map cards in real timeRefer back to earlier messages without interrupting the conversationType back when you can’t talk and still get a Voice responseShare photos to discuss them out loud
This means Voice can better adapt to your day and meet you where you are, whether you're practicing a language and seeing words spelled out, need to refer to a measurement while cooking hands-free, or talking through a chart or code sample where visuals help.
This update is rolling out to all users globally on the ChatGPT mobile app and chatgpt.com. If you prefer the original Voice experience, you can switch back anytime by going to Settings and turning on “Separate mode” under Voice Mode. We’ll continue listening and refining this experience as we build toward Voice interactions that are both integrated and immersive.
