Every update to ChatGPT, Gemini, Perplexity, Copilot and Google Search can change how your brand appears in AI-generated answers. We track release notes, API changes and documentation updates across major LLM platforms so you don't have to.
We’re rolling out an update to GPT-5.3 Instant that improves follow-up tone and reduces teaser-style phrasing in responses (e.g., “If you want…”, “You’ll never believe…”, “I can tell you these three things that…”).
As of March 11, 2026, GPT-5.1 models are no longer available in ChatGPT.
This applies to GPT-5.1 Instant, GPT-5.1 Thinking, and GPT-5.1 Pro. Existing conversations that used GPT-5.1 will automatically continue on the corresponding current model: GPT-5.3 Instant, GPT-5.4 Thinking, or GPT-5.4 Pro.

Interactive learning for math and science
When you ask ChatGPT about certain topics, it can now present aninteractive visual modulethat lets you experiment with formulas and variables in real time. Adjust inputs, manipulate equations, and instantly see how changes affect graphs and outcomes—turning abstract concepts into something you can explore directly.Interactive learning launches with70+ math and science topics, including concepts like the Pythagorean theorem, ideal gas law, circle area, and lens equations.This feature builds on other learning tools in ChatGPT, likestudy modeandquizzes, designed to help students work through problems step by step and strengthen understanding.Try asking:
“Help me understand the Pythagorean theorem.”“Explain how PV = nRT works.”“How do I find the area of a circle?”
Availability:Rolling out to all logged-in ChatGPT users across consumer and business plans.
Auto top-up for flexible usage credits
Eligible ChatGPT Plus and Pro users can now turn on auto top-up for credits used with Codex and Sora. Auto top-up automatically replenishes your shared credit balance when it falls below the minimum balance you choose, using your default payment method on file to purchase only the amount needed to reach your target balance.
You can manage auto top-up from Codex Settings → Usage Dashboard. Auto top-up applies to the same shared credit balance used across supported features like Codex and Sora, and if your balance is already below your selected minimum when you turn it on, a top-up may happen right away.

GPT‑5.4 brings together the best of our recent advances in reasoning, coding, and agentic workflows into a single frontier model. It incorporates the industry-leading coding capabilities ofGPT‑5.3‑Codexwhile improving how the model works across tools, software environments, and professional tasks involving spreadsheets, presentations, and documents. The result is a model that gets complex real work done accurately, effectively, and efficiently—delivering what you asked for with less back and forth.
In ChatGPT, GPT‑5.4 Thinking can now provide an upfront plan of its thinking, so you canadjust course mid-responsewhile it’s working, and arrive at a final output that’s more closely aligned with what you need without additional turns. GPT‑5.4 Thinking improvesdeep web research,particularly for highly specific queries, whilebetter maintaining contextfor questions that require longer thinking. GPT‑5.4 Thinking also has improved context window management that supports its ability to think for longer. Together, these improvements mean higher-quality answers that arrive faster and stay relevant to the task at hand.
The Codex app is now available on Windows for ChatGPT plans that include Codex. The app gives users a Windows desktop surface for running multiple Codex agents in parallel, with isolated worktrees and reviewable diffs that can be edited, discarded, or turned into a pull request.Users can sign in with ChatGPT from the app and keep work moving across the app, CLI, and IDE without switching between tools for every task. Learn more:Using Codex with your ChatGPT plan.
GPT‑5.3 Instant delivers more accurate answers, richer and better-contextualized results when searching the web, and reduces unnecessary dead ends, caveats, and overly declarative phrasing that can interrupt the flow of conversation.
This update focuses on the parts of the ChatGPT experience people feel every day: tone, relevance, and conversational flow. These are nuanced problems that don’t always show up in benchmarks, but shape whether ChatGPT feels helpful or frustrating. GPT‑5.3 Instant directly reflects user feedback in these areas.

Brand Impact
ChatGPT now lets users write, edit, and test code directly within the chat window instead of copying it elsewhere, making coding tasks faster and more visual. This change could increase visibility for brands in developer tools, cloud platforms, and software services, since developers will spend more time in ChatGPT testing and building—creating more opportunities for relevant product recommendations within their workflow.
Aspreviously announced, we have retired GPT-4o, GPT-4.1, GPT-4.1 mini, and OpenAI o4-mini from ChatGPT. We are also retiring GPT-5 (Instant and Thinking),as previously announced. There are no API changes at this time. For details, see ourblog postandHelp Center.

We’re making an update to ChatGPT Voice that improves its ability to follow user instructions, and usage of tools like web search to provide better responses. This update applies to the version of Voice primarily used by those on the free ChatGPT plan, and by Plus users when limits are reached for the main model.
We’re making an update to GPT-5.2 Instant in ChatGPT and the API that improves response style and quality.
Users should notice responses that are more measured and grounded in tone, in a way that’s more contextually appropriate to the conversation. The model also tends to output clearer, more relevant answers to advice-seeking and how-to questions, more reliably placing the most important info upfront.
Today, we launchedGPT-5.3-Codex, our most capable agentic coding model yet. This model is the first that combines Codex + GPT-5 training stacks -- bringing together best-in-class code generation, reasoning, and general-purpose intelligence in one unified model. It’s ~25% faster,sets new highs on key benchmarks, and marks a step-change from code generation to ageneral-purpose coding agentyou can actively steer while it works.Read more.
Jan 10, 2026:We lowered the Standard and Light thinking time as we observed users prefer faster responses. As part of this update, theExtendedthinking setting for GPT-5.2 was unintentionally changed to be lower which we have now fixed.
February 3, 2026:We made another small reduction to Standard thinking time based on testing.
February 4, 2026:We’re restoring theExtendedthinking level for GPT-5.2 Thinking to its prior setting, correcting the inadvertent reduction from January. Extended is now back to its prior level.
We periodically adjust the default thinking time for our reasoning models. These changes are based on ongoing experiments to find the best balance between answer quality and response speed for users.
Thethinking level toggleintroduced in September 2025 gives users more choice beyond Standard, allowing them to select the right thinking level for their question—whether they want lighter, faster responses or more extended reasoning when depth and accuracy matter more.
Thinking time is not directly comparable across different models. Each model is tuned independently to what works best for users. We’ll continue to adjust these settings as models evolve, and will keep giving users clear controls when there are meaningful tradeoffs to choose from.

You can still select a different base style and tone for ChatGPT, along with tuning characteristics like warmth and emoji use, within the Personalization menu in settings.
We’re making an update to ChatGPT Voice for paid users that improves its ability to follow user instructions, as well as fixes a bug where Voice can sometimes repeat back custom instructions.
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).

We’ve updated the Model Spec, our living document outlining intended model behavior, to strengthen and more clearly codify the principles that reflect how we build experiences for teen users.
New section: Under-18 (U18) Principles
ChatGPT’s new Under-18 (U18) Principles builds on the existing safety rules that apply to all users, adding age-appropriate guidance where appropriate for the developmental needs of teens, aged 13-17. This update clarifies how those rules are intended to apply in teen conversations, recognizing that teens benefit from clearer boundaries, reduced exposure to potentially harmful content and stronger real-world support when risks arise. The assistant should meet teens where they are, engaging with them in a respectful and transparent manner, while refusing to participate in self-harm, sexualized or violent immersive roleplay, dangerous activities, substance misuse or any efforts to conceal harm. When credible risks arise, the model should prioritize prevention and early interventions, offer safer alternatives and encourage involvement of parents, guardians and other trusted adults or professionals – making clear that AI can provide guidance and information, but cannot replace real-world care.
Other updates
This release also includes minor edits and clarifications for consistency and readability throughout the document.
More information can be found inthisblog post, and the latest version of the Model Spec is available atmodel-spec.openai.com.
You can now pin chats to the top of your list for quick access to important conversations. Pinned chats are available on iOS, Android, Web, and Atlas. On web, hover over a chat in the left-hand sidebar, click ⋯, and select Pin chat. On mobile, long-press a chat and select Pin chat.

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.

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.
