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.

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.

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.

Creators can now choose from the full set of ChatGPT models (GPT-4o, o3, o4-mini and more) when building Custom GPTs—making it easier to fine-tune performance for different tasks, industries, and workflows. Creators can also set a recommended model to guide users.Key details:

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.
Academic evaluations show that o3-pro consistently outperforms both o1-pro and o3.
To assess the key strength of o3-pro, we once again use our rigorous "4/4 reliability" evaluation, where a model is considered successful only if it correctly answers a question in all four attempts, not just one:
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.
As o3-pro uses the same underlying model as o3, full safety details can be found in theo3 system card.
Limitations
At the moment, temporary chats are disabled for o3-pro as we resolve a technical issue.
Image generation is not supported within o3-pro—please use GPT-4o, OpenAI o3, or OpenAI o4-mini to generate images.
Canvas is also currently not supported within o3-pro.

We're upgrading Advanced Voice in ChatGPT for paid users with significant enhancements in intonation and naturalness, making interactions feel more fluid and human-like. When we first launched Advanced Voice, it represented a leap forward in AI speech—now, it speaks even more naturally, with subtler intonation, realistic cadence (including pauses and emphases), and more on-point expressiveness for certain emotions including empathy, sarcasm, and more.Voice also now offers intuitive and effective language translation. Just ask Voice to translate between languages, and it will continue translating throughout your conversation until you tell it to stop or switch. It’s ready to translate whenever you need it—whether you're asking for directions in Italy or chatting with a colleague from the Tokyo office. For example, at a restaurant in Brazil, Voice can translate your English sentences into Portuguese, and the waiter’s Portuguese responses back into English—making conversations effortless, no matter where you are or who you're speaking with.This upgrade to Advanced Voice is available for all paid users across markets and platforms—just tap the Voice icon in the message composer to get started.This update is in addition to improvements we made earlier this year to ensure fewer interruptions and improved accents.
Known Limitations
In testing, we've observed that this update may occasionally cause minor decreases in audio quality, including unexpected variations in tone and pitch. These issues are more noticeable with certain voice options. We expect to improve audio consistency over time.Additionally, rare hallucinations in Voice Mode persist with this update, resulting in unintended sounds resembling ads, gibberish, or background music. We are actively investigating these issues and working toward a solution.
