LLM/AI Changelog

Today, we’re continuing to retire older models with limited usage in ChatGPT so we can better serve our newer, most capable models. OpenAI o3 will be retired from ChatGPT on August 26, 2026 following a 90-day sunset period, and GPT-4.5 will be retired from ChatGPT on June 26, 2026 following a 30-day sunset period. These models are currently available to paid users only via model settings. These changes apply to ChatGPT only; there are no changes to the API.

Codex is now available in preview in the ChatGPT mobile app, so you can stay connected to active work from your phone while Codex continues running on the connected Mac host. From mobile, you can start or continue threads, answer questions, change direction, approve actions, review what Codex found, and move across connected hosts without stepping away from the work. That means you can keep an investigation moving, make a decision when Codex reaches a fork, or spin up a new idea before you are back at your desk. You can currently connect your phone to Codex running on macOS.The mobile experience loads live context from the machine where Codex is operating, including project context, approvals, plugins, screenshots, terminal output, diffs, and test results. Codex in the ChatGPT mobile app is rolling out on iOS and Android across all plans, including Free and Go, in supported regions. To try it, update both the ChatGPT mobile app and the Codex app on macOS. Setup starts in the Codex App on the host and continues in ChatGPT after scanning a QR code; the host must remain awake, online, and running Codex for remote access to continue.Learn more inRemote connections.

File library is expanding to Free and Go users, including to users in the European Economic Area (EEA) making it easier to find, reuse, and build on files you upload or create in ChatGPT. You can add recent files from the composer, browse saved files in Library, and ask ChatGPT about files you’ve used before, like “What should I know about the document I uploaded yesterday?”We’re also introducing storage management across plans. Storage includes files you upload and files created in ChatGPT, including documents, spreadsheets, presentations, and images. Limits vary by plan:
Free:500 MBGo:4 GBPlusandBusiness:20 GBPro:100 GB
Generated images will continue to appear in the Images tab.Storage management is currently available on web and you can access it from Settings > Storage; you can also delete files directly from Library.Files remain in your Library until you delete them. Files uploaded in Temporary Chat aren’t saved to Library.Library and ‘Recent files’ in the composer are supported on web, iOS, and Android.Learn moreabout File storage and Library in ChatGPT.

Over the coming weeks, we'll be rolling out trusted contact, an optional safety feature for adults with personal ChatGPT accounts.Trusted contact in ChatGPT helps you connect with a person you trust if you need additional support. You may choose your trusted contact in settings, and ChatGPT will send them an  invitation to participate. Once they accept, if automated systems and trained reviewers detect you may be talking about suicide in a way that signals a serious safety concern, ChatGPT may notify your trusted contact and encourage them to check in with you.Trusted contact is available for eligible users with personal ChatGPT accounts in supported regions. It is not available for Business, Enterprise, or Edu workspaces.For more information about this feature and eligibility requirements, seeTrusted contact in ChatGPTand ourblog post.

ChatGPT for Excel and Google Sheets is now available globally, bringing ChatGPT into a sidebar in Microsoft Excel and Google Sheets so you can build, update, and understand spreadsheets in place. It can help with trackers, budgets, formulas, multi-tab files, scenario work, and spreadsheet cleanup, and supports Skills and apps where available.Free and Go include limited usage; Plus and Pro use the same agentic usage limits as Codex. You can purchase additional credits if you need to go beyond plan limits.Install ChatGPT for Excel from Microsoft Marketplace or ChatGPT from Google Workspace Marketplace, then sign in with an eligible ChatGPT account. Review outputs before relying on formulas or analysis.Learn more.

We’re rolling out Advanced Account Security, an optional setting for personal ChatGPT accounts that adds stronger sign-in requirements and stricter account safeguards to help reduce the risk of ATO (account take over), unauthorized access, and data exposure.With Advanced Account Security enabled, ChatGPT uses stronger sign-in methods like passkeys or compatible security keys and turns off weaker paths like password sign-in, email/SMS sign-in codes, and email-based account recovery. It also adds recovery keys, shorter active sessions, login notifications, and session management controls, giving users more protection and visibility across their account.Because these protections are stricter, recovery is also stricter. Users should save their recovery keys and keep access to their enrolled passkeys or security keys. If access to all sign-in methods and recovery keys is lost, access to the account may be lost.

We’re making it easier to choose the right model before you send a message. Model selection now appears in the composer, so you can find and switch models from the same place where you write your prompt.We’re also moving thinking effort controls into the model picker. When you choose a Thinking or Pro model, you can select the level of thinking effort directly from the model picker.This update is available on web to ChatGPT users on Plus, Pro, and Business plans.

We’re introducingChatGPT Images 2.0, our new image generation model in ChatGPT.ChatGPT Images 2.0is available on all ChatGPT plans.We’re also introducingimages with thinking. When given more time to think, it can plan and refine image outputs before generating them.Images with thinkingis available on all paid ChatGPT plans. It is available when you selectThinkingandPromodels.

We’re introducing a new $100/month Pro plan and updating how Codex usage works across Plus and Pro.
Pro ($100/month):Built for longer, high-intensity Codex sessions. It includes unlimited access to GPT-5.4, access to GPT-5.4 Pro, and, for a limited time, up to 10x more Codex usage than Plus (up from 5X standard usage allowance).Pro ($200/month):Our highest-usage option remains available and continues on its current Codex promotion through May 31.Plus ($20/month):Plus remains best for steady, day-to-day use. As the temporary Codex promotion on Plus ends, we’re rebalancing Plus usage to support more sessions across the week, rather than longer, high-intensity sessions on a single day.
You can upgrade, switch, or cancel your plan fromSettings > My Planor from the Pricing page.

The Outlook Email and Calendar apps for ChatGPT can now help with delegated or shared Outlook resources, when you have access. You can ask ChatGPT to read messages from a shared mailbox, browse its folders, mark mail read or unread, move messages, or send plain-text email from or on behalf of that mailbox. For shared Outlook calendars, ChatGPT can help create, update, RSVP to, cancel, delete, or add small attachments to events.To use this, connect the Outlook Email or Outlook Calendar app and provide the exact shared mailbox address or target calendar when asking ChatGPT. Availability may depend on your Microsoft permissions and workspace app settings.Learn more.

We’re rolling out updatedBox,Notion,Linear, andDropboxapps in ChatGPT. These updates add new app actions, including new write capabilities where supported, and bring the latest app experience into ChatGPT.
If you already use these apps in ChatGPT, reconnect the app to start using the updated experience. Existing sync functionality (Pro users only) for these apps is not affected.

Users can now choose to share their device location so ChatGPT can provide more relevant information, such as local recommendations, news, and weather. Sharing your device location is completely optional and off until you choose to enable it. You can update device location sharing in Settings > Data Controls at any time.Enabling location sharing will also enable precise location. Precise location means ChatGPT can use your device’s specific location, such as an exact address, to provide more tailored results. For example, if you ask “what are the best coffee shops near me?”, ChatGPT can use your precise location to provide more relevant nearby results. On mobile devices, you can choose to toggle off precise location separately while keeping approximate device location sharing on for additional control.ChatGPT deletes precise location data after it’s used to provide a more relevant response. If ChatGPT’s response includes information related to your specific location, such as the names of nearby restaurants or maps, that information becomes part of your conversation like any other response and will remain in your chat history unless you delete the conversation.Parents who have set up parental controls can choose to disable device location sharing for their teen.Rolling out to all ChatGPT consumers plans on iOS and web today. Android is coming soon.

Codex now includes a curated plugins directory that lets users discover, install, and use packaged workflows built from apps and skills directly in Codex. Plugins are installable bundles for reusable Codex workflows, making it easier to share the same setup across projects or teams. Plugins can package skills, optional app integrations, and MCP server configurations in a single place.Learn more.

Starting today forChatGPT Plus,Pro, andBusinessusers, long pastes are handled differently in ChatGPT.If you pastemore than 5k charactersinto the composer, ChatGPT will automatically convert the content into anattachmentinstead of inserting it directly into the text field. This keeps the composer cleaner and helps prevent large pastes from consuming your entire context window.You can still move the content back into the message at any time by clicking onShow in text fieldto convert the attachment back to a direct paste.

Google’s file connectors in ChatGPT are now unified under Google Drive, providing a single app experience for interacting with your Google Docs, Sheets and Slides on Google Drive.If you’re a new user, you can connect to the Google Drive app in ChatGPT to use Google Drive, Docs, Sheets, and Slides actions, removing the need to install and authenticate separate Google file apps. If you’ve already connected to the separate apps in the past, they will continue to work as normal. You can also reconnect the Google Drive app to get the new actions - ChatGPT will switch over once you’ve done the reconnection.For Pro users, Google Drive sync behavior is unchanged.Read more.

Now, it’s easier to find, reuse, and build on your files over time. When you upload or create a file—whether it’s a PDF, spreadsheet, image, or more—it’s automatically saved to your Library. Generated images will continue to appear in the Images tab.You can quickly reference files in a chat using recent files in the composer, or browse everything you’ve uploaded in the Library tab in the sidebar. You can also ask ChatGPT about files you’ve saved (“What should I know about the document I uploaded yesterday?”)Library is available on web only. ‘Recent files’ in the composer and file search in ChatGPT are supported on iOS and Android.Files remain in your Library until you delete them. Files uploaded in Temporary Chat are not saved to your Library.Availability:Rolling out globally for Plus, Pro, and Business users, coming soon to users in the European Economic Area, Switzerland, and the United Kingdom.

Codex for Students is now available for verified university students in the United States and Canada. Eligible students can claim $100 in ChatGPT credits, or 2,500 credits, to extend Codex usage beyond the limits included in ChatGPT Free, Go, Plus, and Pro.
To get started, students sign in at chatgpt.com/codex/students and complete student verification through SheerID with their university email. Credits are applied automatically to the student's personal workspace, can be used in Codex, are not API credits, and expire 12 months after the grant date.Learn more.

We’re rolling out GPT-5.4 mini in ChatGPT. GPT-5.4 mini is available to Free and Go users via the “Thinking” feature in the + menu. For all other users, GPT-5.4 mini is available as a rate limit fallback for GPT-5.4 Thinking.For Plus, Pro, and other paid users, GPT-5.4 mini will be used as a fallback for GPT-5.4 Thinking when rate limits are reached, helping with continued access to reasoning capabilities during high usage. Enterprise customers will retain the option to default Auto routing to GPT-5.4 mini, if preferred.GPT-5.4 mini will not appear as a selectable model in the model picker, and GPT-5 Thinking mini will be retired as a selectable option in 30 days. Learn more in ourblog post.

We’ve simplified the model picker to make it easier to choose the right level of reasoning.Users on Plus, Pro, Business, Enterprise, and Edu accounts will see a set of model options depending on their plan, including:
Instant– fast responses for everyday questionsThinking– deeper reasoning for more complex tasksPro– the most advanced reasoning models
The Auto functionality can be accessed by clickingConfigurein the model picker menu and choosing "Auto-switch to Thinking.” This setting will automatically be on if your last chat was set to Auto.
Configure more advanced settings
If you want more control, clickConfigureto:

We’ve also simplified theretry menu, making it easier to regenerate responses with Thinking or Pro models by clicking on the three dots underneath the response.

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. Learn more:Using Credits for Flexible Usage in ChatGPT (Free/Go/Plus/Pro) & Sora.

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.

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.

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.

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.

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.

Tasks let you set up automated prompts that ChatGPT can run for you.You can now manage all your tasks directly in Pulse:

We’re retiring the Voice experience in the ChatGPT macOS app on January 15, 2026. This change allows us to focus on more unified and improved voice experiences across our apps.
Voice will continue to be available onchatgpt.com, iOS, Android, and Windows app.No other ChatGPT features on macOS are affected.

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.

ChatGPT now adds more inline images from the web to help you quickly understand topics like well-known people, places, and products. When visuals can add clarity, you’ll see images placed beside the relevant paragraph. You can click on any of the images to see them in original dimensions and with the source attribution.
These improvements are gradually rolling out globally across all ChatGPT plans, on web, iOS, and Android for responses using GPT 5.1.

You can now find and buy from Shopify merchants starting with Spanx, Skims, and Glossier through Instant Checkout in ChatGPT.
When a product from a Shopify merchant supports Instant Checkout, you can complete the purchase right in thechat with a quick confirmation of your shipping and payment details.
Instant Checkout is available for logged in Plus, Pro, and Free users in the US.

Today we’re updating GPT-5 Pro to GPT-5.1 Pro. In early testing, users consistently preferred GPT-5.1 Pro over GPT-5 Pro, rating it especially highly for writing help, data science, and business questions. Testers highlighted the model’s improved clarity, relevance, and structure in its responses.
GPT-5.1 Pro is rolling out today for all ChatGPT Pro users and is available in the model picker. GPT-5 Pro will remain available as a legacy model for 90 days before being retired.

We’re piloting group chats so you can bring people - and ChatGPT - into the same conversation. Plan trips, make decisions, and collaborate on projects together while ChatGPT helps search, summarize, generate content, and keep everyone on the same page.
Group chats are starting to roll out on ChatGPT Web, iOS, and Android in New Zealand, Japan, South Korea, and Taiwan. We’ll use early feedback from this pilot to improve the experience and inform how we expand to more regions and plans over time. To learn more visit theblog.
