LLM/AI Changelog

We’re updating GPT-5 to GPT-5.1 Instant and GPT-5.1 Thinking, making answers both smarter and more conversational. GPT-5.1 Instant now uses light adaptive reasoning for tougher questions while staying fast, and GPT-5.1 Thinking adapts its thinking time more precisely for complex tasks with clearer, less jargony responses.
GPT-5.1 Auto continues to route each query to the best model, and GPT-5 models remain available for three months under the Legacy models dropdown so you can compare and transition at your own pace.
GPT-5.1 Instant and Thinking are rolling out first to paid (Pro, Plus, Go, Business) users, then to free and logged-out users, with Enterprise and Edu getting a temporary early-access toggle; GPT-5.1 will also be available soon in the API as gpt-5.1-chat-latest (Instant) and gpt-5.1 (Thinking).

We’re updating ChatGPT’s tone controls so it’s easier to make responses sound the way you prefer. You can now choose from updated presets like Default, Friendly, Efficient, Professional, Candid, and Quirky (with Cynical and Nerdy still available), and we’re experimenting with more granular controls over how concise, warm, or scannable responses are, plus how often emojis appear.
Changes you make in Personalization now apply across all chats immediately (including existing conversations), and GPT-5.1 models follow your custom instructions and style preferences more reliably.

Previously, changes you made to your ChatGPT personality or custom instructions only applied to new conversations. Starting today, updates you make in Settings → Personalization are applied immediately across all chats (including existing conversations!) so your experience stays consistent everywhere without needing to start a new thread.

You can now interrupt long-running queries (such as deep research or GPT-5 Pro) to refine what you’re asking—no restart required or progress lost. For example, if you're researching the perfect bookshelf and suddenly remember that your wall is 72" wide and you can't drill into it, you can simply add that information midstream by clicking “update” in the sidebar and sending the new information as a message. The model will adjust its approach based on your new requirements.

With Pulse, ChatGPT can do asynchronous research on your behalf once a day based on your past chats, memory, and feedback to help you get things done. The research is delivered to you proactively the next day as a series of visual summaries that you can scan at a glance, expand for more detail, save for later, or ask follow up questions.

ChatGPT Go now available in Brazil
We're launching ChatGPT Go, our low cost subscription plan, in Brazil. ChatGPT Go provides everything included in theFreeplan, and:
More messages, larger file uploads, and expanded image generationAccess to advanced data analysisLonger memory for more personalized responses
Available on web, mobile (iOS & Android), and desktop (macOS & Windows).
Learn more aboutChatGPT Go.

Shared projects
Starting today, project sharing is available to all ChatGPT users, including for Free, Plus, Pro, and Go users globally on web, iOS, and Android.
ChatGPT can draw from anything in the shared project – including chats, uploaded files and custom instructions – so responses are informed by your group's internal knowledge, and you can pick up where others left off.
Shared projects are ideal for:
Group work: Upload notes, proposals, and contracts so collaborators can draft deliverables faster and stay in sync.Content creation: Apply project-specific instructions to keep tone and style consistent across contributors.Reporting: Store datasets and reports in one project, and return each week to generate updates without starting over.Research: Keep transcripts, survey results, and market research in one place, so anyone in the project can query and build on the findings.
Project owners can choose to share a project with “Only those invited” or “Anyone with a link,” and can change visibility settings at any time including switching back to invite-only. The following collaboration limits apply:
Pro users:up to 40 files and 100 collaborators​Plus and Go users:up to 25 files and 10 collaborators​Free users:up to 5 files and 5 collaborators

ChatGPT now manages saved memories automatically by keeping the most relevant details prioritized and moving less important ones to the background. This helps prevent saved memories from reaching capacity and helps avoid “memory full” state in your ChatGPT account.
To decide which memories stay top of mind, ChatGPT considers factors such as how recent a detail is and how often you talk about a topic. You can now also search your saved memories more easily and sort them by newest or oldest.
You’re always in control: you can turn off automatic memory management at any time, and you can see which memories are currently top of mind and choose to prioritize or deprioritize any specific memory yourself in settings. You can also view and restore prior versions of saved memories.
These updates are designed to make saved memory feel seamless, reliable, and easy to manage. We’re beginning to roll this out to Plus and Pro users globally on the web.

We're excited to announce that ChatGPT Go, our low cost subscription plan, is now available in71 additional countries, bringing total coverage to89 countries.
For an affordable price, ChatGPT Go provides everything included in theFreeplan, and:
More messages, larger file uploads, and expanded image generationAccess to advanced data analysisLonger memory for more personalized responses
Available on web, mobile (iOS & Android), and desktop (macOS & Windows).
Note:In Cambodia, Laos, and Nepal, ChatGPT Go subscriptions aren’t available in the iOS app currently. Web and Android subscriptions remain available.

We’re rolling out two new ways to bring Slack and ChatGPT together: aconnectorthat brings your Slack context into ChatGPT, and a ChatGPT app for Slack – an integration that enables you to chat with ChatGPT from inside Slack.
With theChatGPT app for Slack,you can chat one-on-one with ChatGPT in a dedicated Slack sidebar – a space to ask questions, summarize long threads into action items, draft replies, and search messages and files you already have access to. Chats you start in Slack also appear in your ChatGPT sidebar, so it’s easy to pick up later from web or mobile. Semantic search is supported for Slack customers with AI enabled on Business+ or Enterprise+ plans; all other plans use keyword search.
With theChatGPT connector for Slack,you can securely bring in context from your Slack channels and DMs, making responses more helpful Available in chat, Deep Research, and Agent Mode. Users can enable fromSettings > Apps & Connectors.
Both app and connector are available toPlus, Pro, Business and Enterprise/Educustomers. Additionally, the ChatGPT app for Slack requires apaid Slack account;availability and workspace installation may depend on your Slack workspace settings.
Installing the app requires the connector to be enabled for your account.
Visit theChatGPT app for Slackpage to get started with installation.

We're addingNotionandLinearas synced connectors (for Pro users), so you can securely bring Notion pages and Linear issues/discussions into Chat for fast answers and summaries. You can enable sync for Notion and Linear from your Connector settings (connect to Notion or Linear if you haven’t already, first). Once synced, ChatGPT will automatically reference the indexed content when relevant. Learn more aboutsynced connectors.

Updating GPT-5
We’re updatingGPT-5 Instantto better recognize and support people in moments of distress.
The model is trained to more accurately detect and respond to potential signs of mental and emotional distress. These updates were guided by mental health experts, and help ChatGPT de-escalate conversations and point people to real-world crisis resources when appropriate, while still using language that feels supportive and grounding.
As we shared in arecent blog, we've been using our real-time router to direct sensitive parts of conversations—such as those showing signs of acute distress—to reasoning models. GPT-5 Instant now performs just as well as GPT-5 Thinking on these types of questions. When GPT-5 Auto or a non-reasoning model is selected, we'll instead route these conversations to GPT-5 Instant to more quickly provide helpful and beneficial responses. ChatGPT will continue to tell users which model is active when asked.
This update to GPT-5 Instant is starting to roll out to ChatGPT users today.We’re continuing to work on improvements and will keep updating the model to make it smarter and safer over time.

We’re rolling out parental controls globally in ChatGPT to help families guide how ChatGPT works in their homes. Available starting on the web today, mobile soon.
To set up parental controls, a parent or guardian sends an invite to their teen to connect accounts. After the teen accepts, the parent can manage the teen’s settings from their own account. Teens can also invite a parent to connect.
Once a teen is connected to a parent’s account, they automatically receive additional content protections, such as reduced graphic content and viral challenges. Parents will have the option to turn this setting off if they choose, but teen users cannot make changes.
Parents don’t have access to their teen’s conversations, except in rare cases where our system and trained reviewers detect possible signs of serious safety risk, parents may be notified — but only with the information needed to support their teen’s safety. Parents can choose if they’d like to be contacted by email, SMS, push notification, or all three.
Parents can adjust certain features, set time limits, and add safeguards that work for their family including:
Set quiet hours, or specific times when ChatGPT can’t be used.Turn off voice mode, to remove the option to use voice mode in ChatGPT.Turn off memory, so ChatGPT won’t save and use memories when responding.Remove image generation, so ChatGPT won’t have the ability to create or edit images.Opt out of model training,so their teen’s conversations won’t be used to improve models powering ChatGPT and Sora.

We’re launching an early preview of ChatGPT pulse forPro users on iOS and Android. This is a new experience where ChatGPT can now proactively deliver personalized, focused updates for you once a day. These updates are based on asynchronous research ChatGPT can do on your behalf overnight, synthesizing information from your memory, chat history, and direct feedback to learn what’s most relevant to you.
Updates are delivered once a day as visual summaries you can scan at a glance or dive deeper into. Each topic opens into more detail where you can ask follow-up questions. You can shape what shows up in pulse with a quick thumbs up or down, or by using curate to tell ChatGPT what you’d like to see.
If you ask for something new in the evening, we aim to include it the next morning, though exact timing may vary. Pulse refreshes daily, and you can save any item into a chat to keep it.
As a preview, pulse has some limitations. It aims to show you what’s most relevant and useful but you may still see suggestions that miss the mark. For example, you may get tips for a project you already completed. You can guide what shows up by telling ChatGPT directly. It remembers your feedback for next time and improves as it learns from real use.
It requires saved memory and chat history to be turned on, and you can switch pulse off anytime in settings. SeeChatGPT Pulse.

We're launching ChatGPT Go, our low cost subscription plan, in Indonesia.
For Rp 75.000/month, ChatGPT Go provides everything included in theFreeplan, and:
More messages, larger file uploads, and expanded image generationAccess to advanced data analysisLonger memory for more personalized responses
Available on web, mobile (iOS & Android), and desktop (macOS & Windows).

What’s new
We’re giving Plus, Business, and Pro users more control over how long GPT-5 thinks before responding. You can now choose the level of reasoning time, so you can decide whether you want a quicker answer or more in-depth reasoning for your task.
How it works
When you selectGPT-5 with Thinkingin ChatGPT, you’ll see a newthinking timetoggle in the message composer.
Standard(new default, balancing speed and intelligence) andExtended(the previous default for Plus) are available to allPlus, BusinessusersProusers get two additional options:Light(snappiest) andHeavy(deeper reasoning).All queries default toStandardunless you choose to change it. Once you choose a different thinking time, your preference is saved and used for future queries until you switch again.
Why we’re making this change
We’ve heard from some of you that GPT-5 Thinking’s answers can take longer than you’d like. Now you can decide what you need in the moment:
Light / Standard→ quicker answers that still apply reasoning, balancing speed and intelligence.Extended / Heavy→ more time for deeper, more comprehensive responses when the stakes are higher or the question is more difficult.
What’s next
The thinking-time toggle is live today on chatgpt.com. Settings you choose on the web won’t yet sync to mobile, but we’ll bring this control to our iOS and Android apps in the coming weeks.

We’re adding GPT-5-codex, a GPT-5 variant optimized for agentic coding in Codex. It’s available everywhere you use Codex: default for cloud tasks and code review, and selectable for local workflows via the Codex CLI and IDE extension. Use GPT-5-codex for coding-focused work in Codex, or Codex-like environments; use GPT-5 for general, non-coding tasks. Please review theannouncementblog for more information.
Note: GPT-5-Codex is not currently supported in ChatGPT or the API.
To learn more about Codex, visit thedevelopers siteas well as our general help article:Using Codex with your ChatGPT plan.

Last month we announced that everyone now has access to Advanced Voice Mode, with usage expanded from minutes per day to hours for Free users, and near-unlimited use for Plus.
We also shared that Standard Voice Mode would be retired following a 30-day sunset period. We’ve heard feedback that Standard Voice is special to some folks, and we want to make sure the transition feels right. To that end, we’re keeping Standard Voice available while we address some feedback from its users about Advanced Voice.
Stay tuned—more improvements to Voice are coming soon.

You can now branch conversations in ChatGPT, making it easier to explore different directions without losing your original thread. Hover over a message, clickMore actions(⋯), and selectBranch in new chatto start a separate conversation from that point.
This feature is available today for all logged-in users on web.

Projects bring your chats and files into one place, helping you stay focused and get things done. They’re now available on our Free tier, with up to 5 file uploads per project.
We’ve also updated file uploads on paid tiers: Plus, Go, and Edu support up to 25 files per project. Pro, Business, and Enterprise support up to 40 files per project.
New customization options are available for all plans, including colors and icons, to help keep your projects organized.
Learn more aboutprojects in ChatGPT.

Starting today, Codex works with you everywhere you build—in your terminal or IDE, on the web, in GitHub, and even from the ChatGPT iOS app. Your ChatGPT account connects it all, so you can work seamlessly between your local environment and Codex’s cloud without losing state.
We’re excited to introduce the latest Codex updates:
IDE Extension:The new extension brings codex into VS Code, Cursor, and other VS Code forks, so that you can seamlessly preview local changes and edit codeSign in with ChatGPT:Available in both the IDE and CLI, eliminating API key setup and providing access directly through your existing ChatGPT planSeamless Local ↔ Cloud Handoff:Developers can pair with Codex locally and then delegate tasks to the cloud to execute asynchronously without losing stateUpgraded Codex CLI:Refreshed UI, new commands, and bug fixesCode reviews in GitHub:Set up Codex to automatically review new PRs in a repo, or mention @codex in PRs to get reviews and suggested fixes
Additionally, all product information and updates for Codex moving forward will be announced on our new site:developers.openai.com/codex.
We invite you to explore the site for more details on these new features, as well as guides on how to get started.
To learn more about Codex, visit the newdevelopers siteas well as our general help article:Using Codex with your ChatGPT plan.

An improvement toprojectsis now available. When creating a project, users have the option to enableproject-only memory.
Withproject-only memoryenabled, ChatGPT can use other conversations in that project for additional context, and won’t use yoursaved memoriesfrom outside the project to shape responses. Additionally, it won’t carry anything from the project into future chats outside of the project.
This creates a focused, self-contained space, which is useful for long-running or sensitive work where you want ChatGPT to stay anchored to that project’s tone, context, and history.
Note:
Personal Memorymust be enabled to utilize this feature.Settings->Personalization->MemoryThis feature will initially only be available on the ChatGPT website and Windows app. Support for mobile (iOS and Android) and macOS app will follow in the coming weeks.

We’re making GPT-5’s default personality warmer and more familiar. This is in response to user feedback that the initial version of GPT-5 came across as too reserved and professional. The differences in personality should feel subtle but create a noticeably more approachable ChatGPT experience.
Warmth here means small acknowledgements that make interactions feel more personable — for example, “Good question,” “Great start,” or briefly recognizing the user’s circumstances when relevant. This is different from sycophancy, which we define as excessive flattery that can feel insincere. You can find more about our learnings on reducing sycophancyhere.
This update does not show an increase in sycophancy compared to the previous personality of GPT-5, measured by the same internal evals we ran and detailed in oursystem card. Teaching models to be warm without being sycophantic is an ongoing research challenge, and we will continue iterating to get this right. More updates are coming soon.

You can now choose between “Auto”, “Fast”, and “Thinking” for GPT-5. Most users will want Auto, but the additional control will be useful for some people.
ChatGPT Plus users now have 3,000 messages/week with GPT-5 Thinking, and then extra capacity on GPT-5 Thinking mini after that limit. The context limit for GPT-5 Thinking is 196k tokens. We may have to update rate limits over time depending on usage.
4o is back in the model picker for all paid users by default. Paid users also now have a “Show additional models” toggle in ChatGPT web settings which will add models like o3, o4-mini, 4.1, and GPT-5 Thinking mini. 4.5 is only available to Pro users due to GPUs.

Gmail, Google Calendar, and Google Contacts are now available to connect and use in chat. Once you enable them, ChatGPT will automatically reference them when relevant, making it faster and easier to bring information from these tools into your conversations without having to manually select them each time.
This capability is part of GPT-5 and will begin rolling out to Pro users globally this week, followed by Plus, Team, Enterprise, and Edu plans in the coming weeks. To enable, visitSettings→Connectors→Connecton the application.
If you already have Gmail or Google Calendar enabled for deep research, you can now also use them in chat. To use them in deep research, you will still need to enable each connector separately and select it every time you start a new deep research request.
Learn more aboutconnectors.

Now connect even more tools in ChatGPT for useful, relevant responses in chat.
The following connectors are now available to search by chat in addition to deep research.
Plus:Box, Canva, Dropbox, HubSpot, Notion, Microsoft SharePoint, and Microsoft TeamsPro: Microsoft Teams and Github
Rollout begins today, and all eligible accounts will have access in the coming days.
To enable, visitSettings→Connectors→Connecton the application. Note that connectors are still in beta and defaulted off for Enterprise & Edu plans. Admins can enable them for their workspace inSettings.
Note:Connectors for Plus/Pro plans are not available in EEA, Switzerland, and the UK.

GPT-5 is slowly rolling out to all users on ChatGPT Plus, Pro, Team, and Free plans worldwide across web, mobile, and desktop. GPT-5 will be available to ChatGPT Enterprise and Edu plans soon.
GPT-5 in ChatGPT is our next flagship model and the new default for all logged-in users. It simplifies ChatGPT to a single auto-switching system that brings together the best of our previous models into asmart, fast model.
GPT-5 is available to all ChatGPT Tiers. Users on Paid tiers - Plus, Pro, and Team - have access to the model picker, which enables you to manually select GPT-5 or GPT-5 Thinking. Pro and Team tier users have access to GPT-5 Thinking Pro, which takes a bit longer to think but delivers the accuracy you need for complex tasks.
Learn more about GPT-5 in ChatGPT.

You can now choose from four distinct personalities or use the Default personality in yourCustomize ChatGPT settings. Default is the standard ChatGPT style: clear, neutral, and adaptable. The other personalities each have their own style and tone, described below.
Cynic– Sarcastic and dry, delivers blunt help with wit. Often teases, but provides direct, practical answers when it matters.
Robot– Precise, efficient, and emotionless, delivering direct answers without extra words.
Listener– Warm and laid-back, reflecting your thoughts back with calm clarity and light wit.
Nerd– Playful and curious, explaining concepts clearly while celebrating knowledge and discovery.
Please note that these personalities will not apply to Voice mode.

You can now set an accent color that applies to elements in ChatGPT, including your conversation bubbles, the Voice button, and highlighted text.
On web:Click your profile icon at the bottom left, selectSettings, go to theGeneraltab, and choose an option from theAccent colordrop-down.
On mobile (iOS and Android):Tap your profile icon at the bottom, go toPersonalization, then selectColor Schemeto pick your accent color.

Today we’re rolling out improvements to Voice Mode to make it more accessible and useful for everyone. It also now works with custom GPTs. We’re expanding access with near-unlimited use for Plus users and hours each day for Free users. To simplify the experience, Standard Voice Mode will be retired in 30 days, unifying all users onto our latest voice experience.
For paid users, Voice now adapts to your instructions, adjusting its speaking style (length, speed, tone, and more) to fit the moment.

Study mode is currently available to users in Free, Plus, Pro, and Teams plans globally and will expand to Edu plans in the coming weeks. Study mode works with any model available in ChatGPT on iOS, Android, web, and desktop.
Study mode is a new learning experience in ChatGPT designed to help you build a deeper understanding of any topic. When you turn it on, ChatGPT will ask interactive questions to understand your goals and skill level, then work with you to reach the answer together.
With Study mode enabled, ChatGPT can:
Guide understanding with Socratic-style questions.Break concepts into easy to follow sections starting simple and adding complexity as you progress.Personalize responses based on your past chats if memory is on, using examples and tips tailored to you.Check your understanding with open-ended prompts and feedback.Work with your materials by referencing images or PDFs you upload.
You can enable study mode at any time by selectingToolsin the prompt window and choosingStudy and learnfrom the drop‑down menu or go tochatgpt.com/studymode.
Study mode is powered by custom system instructions and can have some inconsistent behavior and mistakes across conversations. We plan on training this behavior directly into our main models once we’ve learned what works best through iteration and user feedback.
Learn more about study mode.

Record mode is now available to ChatGPT Plus users globally in the macOS desktop app.
