Model Release Notes
June 04, 2026
ChatGPT Update
We've upgraded memory so ChatGPT can better keep your context up to date, helping responses stay more relevant. This makes memory more useful by reducing stale or contradictory saved memories and helps ChatGPT better understand your preferences, goals, and ongoing work. You can review the memories that ChatGPT may use to personalize responses through sources or in your memory summary. Memories are now updated automatically, with ChatGPT keeping track of the details it determines are most important so it can continue building on the context you've already shared. If you prefer to revert to the legacy saved memories system, go to Settings > Memory > Saved memories. This update is rolling this out to Plus and Pro users in the US today. To access it on iOS or Android, update your ChatGPT app to the latest version. We'll expand to Free and Go plans and additional countries over the next few weeks. Users will receive an in-product notice when the update becomes available to them. For Plus and Pro users, ChatGPT can also remember more useful context, with twice as much memory capacity.
June 01, 2026
ChatGPT Update
ChatGPT can now help with more of the job search process, from finding relevant live roles to tailoring a resume for a specific opportunity. When you search for jobs, ChatGPT can surface live listings and freelance opportunities from sources like Indeed, Upwork, Appcast, and across the web. Results are personalized using your experience, skills, and goals to highlight roles that may be a strong fit. You can follow links to apply directly on the source sites. You can now also upload or create a resume in ChatGPT, tailor it to a specific role, and download it in a polished, professional format. Job search: Available to users in the U.S. on Free, Go, Plus, and Pro plans. Resume formatting: Available in English globally on the web for all plans.

We're rolling out Fast answers, a quicker way to get responses to common information-seeking questions in ChatGPT, like 'Show me the Seven Wonders of the World' or 'Which football team has the most super bowl titles?' When your question doesn't require a personalized response and ChatGPT has a high-confidence answer ready, it can now respond faster while still providing a useful, in-depth answer. Fast answers do not reference your past chats or memory. Fast answers are available globally on web, iOS, and Android for logged in and logged out users across plans. If you prefer ChatGPT to always generate personalized answers, you can turn Fast answers off anytime in Personalization settings.
April 09, 2026
GPT-5.3 Instant Mini
Today, we're releasing GPT-5.3 Instant Mini in ChatGPT. It replaces GPT-5 Instant Mini as the fallback model users reach after hitting their rate limits for GPT-5.3 Instant. Because it serves as a fallback, it won't appear in the model picker.
Compared with GPT-5 Instant Mini, GPT-5.3 Instant Mini feels more natural in conversation, with stronger writing and contextual awareness throughout chats. It outperforms GPT-5 Instant Mini across a range of use cases.
March 26, 2026
ChatGPT Update
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.
March 24, 2026
ChatGPT Update
We've improved shopping in ChatGPT to make it easier to discover, compare, and decide on products. Product results are now more visually rich, with improved detail and relevance. You can browse products in chat, refine results through conversation, and upload images to find similar items. Products can also be compared side by side with key details such as price, reviews, and features, making it easier to compare without opening multiple tabs. We've also improved product data coverage, freshness, and speed so results are more up to date and useful. These improvements are rolling out to all ChatGPT users this week. These updates improve how ChatGPT retrieves and presents product information from merchants and other providers using the Agentic Commerce Protocol (ACP).
March 18, 2026

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.
October 03, 2025
GPT-5 Instant
We're updating GPT-5 Instant to 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 a recent 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.
September 29, 2025

An enhanced version of Gemini 2.5 Flash is now available to Gemini app users. Responses are now better organized with improved formatting. Gemini 2.5 Flash uses elements like headers, lists, and tables to make even complex outputs clearer and easier to understand. We've also improved image understanding, so Gemini can better interpret and respond to your uploads.

ChatGPT Update
We're launching an early preview of ChatGPT Pulse for Pro 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.

GPT-4o mini
We're improving the quality and latency of responses of the version of Advanced Voice powered by GPT-4o mini.
September 17, 2025
GPT-5
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. When you select GPT-5 with Thinking in ChatGPT, you'll see a new thinking time toggle in the message composer. Standard (new default, balancing speed and intelligence) and Extended (the previous default for Plus) are available to all Plus, Business users. Pro users get two additional options: Light (snappiest) and Heavy (deeper reasoning). All queries default to Standard unless you choose to change it.

ChatGPT Update
We've made further improvements to search in ChatGPT, making results more accurate, reliable, and useful. Factuality: Fewer hallucinations, improving answer quality. Shopping: Search is better at detecting shopping intent, showing products when you want them and keeping results focused when you don't. Formatting: Answers are better formatted for quick understanding without losing detail or quality.

ChatGPT Update
An improvement to projects is now available. When creating a project, users have the option to enable project-only memory. With project-only memory enabled, ChatGPT can use other conversations in that project for additional context, and won't use your saved memories from 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.
August 15, 2025
GPT-5
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. This update does not show an increase in sycophancy compared to the previous personality of GPT-5.

GPT-5
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. 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.

GPT-5
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 a smart, fast model.
August 07, 2025
ChatGPT Update
Personalities: You can now choose from four distinct personalities or use the Default personality in your Customize ChatGPT settings. Default is the standard ChatGPT style: clear, neutral, and adaptable. The other personalities each have their own style and tone: Cynic – Sarcastic and dry, delivers blunt help with wit. 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.
August 07, 2025
ChatGPT Update
ChatGPT Voice updates: Rolling out improvements to Voice Mode to make it more accessible and useful for everyone. It now works with custom GPTs. Expanding access with near-unlimited use for Plus users and hours each day for Free users. Standard Voice Mode will be retired in 30 days, unifying all users onto the 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.

Gemini Update
Gemini now provides a richer learning experience by automatically integrating high-quality images, diagrams, and YouTube videos directly into its responses. When you ask about complex topics like photosynthesis or the parts of a cell, Gemini will seamlessly weave in visuals and YouTube videos alongside the text to help you understand the information more easily. Integration of high quality images, diagrams and YouTube videos is available to all users.
August 06, 2025
Gemini Update
Gemini now offers Guided Learning, a new mode designed to help you build a deeper understanding of whatever you're trying to learn or do. Instead of providing a single answer, this feature guides you through subjects step-by-step, breaking down concepts and providing interactive help along the way. It's ideal for understanding complex information or developing a new skill. You can activate this tool using the 'Guided Learning' chip on desktop or the 'Learn' chip on mobile. This experience is open to all users.

Gemini 2.5 Deep Think
Starting today, Google AI Ultra subscribers get early, limited access to Gemini 2.5 Deep Think, Gemini's most advanced reasoning mode. Deep Think is capable of thinking for longer and generating multiple parallel streams of thought simultaneously—much like how humans brainstorm to tackle complex problems – making it excel at iterative development and design, scientific and mathematical research, and coding.
July 29, 2025
ChatGPT Update
Study Mode is currently available to users in Free, Plus, Pro, and Teams plans globally. 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. It can guide understanding with Socratic-style questions, break concepts into sections, personalize responses based on past chats, check understanding with open-ended prompts, and work with uploaded images or PDFs.
July 17, 2025
ChatGPT Update
Updates to Advanced Voice Mode for Free tier users: The Advanced Voice upgrades announced on June 7th are now rolling out to ChatGPT free users too. With the same improvements available to paid users, ChatGPT sounds more natural and expressive, and can translate more effectively. Rate limits for free users stay the same.
June 13, 2025
ChatGPT Update
We've upgraded ChatGPT search for all users to provide even more comprehensive, up-to-date responses. In testing, we found users preferred these search improvements over our previous search experience.
### Improved quality
- Smarter responses that are more intelligent, are better at understanding what you're asking, and provide more comprehensive answers.
- Handles longer conversational contexts, allowing better intelligence in longer conversations.
### Improved search capability and instruction following
- More robust ability to follow instructions, especially in longer conversations, significantly reducing repetitive responses.
- Capability to run multiple searches automatically for complex or difficult questions.
- Search the web using an image you've uploaded.
### Known limitations
- Users may notice longer responses with this new search experience.
- In some cases, a "chain of thought" reasoning will show up unexpectedly for simple queries. A fix for this is rolling out to users shortly.
- ChatGPT may still make occasional mistakes - please double check responses.

o3-pro
Today, we're launching OpenAI o3-pro—available now for Pro users in ChatGPT and in our API. Like o1-pro, o3-pro is a version of our most intelligent model, o3, designed to think longer and provide the most reliable responses. Since the launch of o1-pro, users have favored this model for domains such as math, science, and coding—areas where o3-pro continues to excel, as shown in academic evaluations. Like o3, o3-pro has access to tools that make ChatGPT useful—it can search the web, analyze files, reason about visual inputs, use Python, personalize responses using memory, and more. Because o3-pro has access to tools, responses typically take longer than o1-pro to complete. We recommend using it for challenging questions where reliability matters more than speed, and waiting a few minutes is worth the tradeoff.
In expert evaluations, reviewers consistently prefer o3-pro over o3 in every tested category and especially in key domains like science, education, programming, business, and writing help. Reviewers also rated o3-pro consistently higher for clarity, comprehensiveness, instruction-following, and accuracy.
o3-pro is available in the model picker for Pro and Team users starting today, replacing o1-pro. Enterprise and Edu users will get access the week after.
June 03, 2025
ChatGPT Update
Memory improvements are starting to roll out to Free users. In addition to the saved memories that were there before, ChatGPT now references your recent conversations to deliver responses that feel more relevant and tailored to you.
Free users must be logged in and on up-to-date apps (iOS/Android v1.2025.147+).
### Opt-in reminders
- Free users in EEA (EU + UK), Switzerland, Norway, Iceland, or Liechtenstein will see a prompt to enable this setting or can visit Settings > Personalization > Memory > Reference chat history to enable.
- Outside the European regions listed above, all Free users that have memory enabled will receive the upgrade automatically.
You can turn off memory anytime in settings.
