ChatGPT Updates & Release Notes

Trusted contact 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.

Memory sources and more personalized responses in ChatGPT

Starting today, we’re rolling out memory improvements to ChatGPT Plus and Pro users that make responses more personalized, useful, and continuous over time. ChatGPT can now better pull in relevant context from your past chats, saved memories, and, where available, files and connected Gmail app, to offer more tailored ideas, recommendations, and next steps. It is also faster at searching past conversations to find the right context, so you don’t have to repeat yourself as often.

We’re also introducing memory sources across all ChatGPT consumer plans, so you can see what information helped personalize a response and make edits if something is no longer relevant. Tap the Sources icon below the response to view relevant saved memories, past chats, and custom instructions. Plus and Pro users may also see files in their library and referenced emails from a connected Gmail account. If something is outdated or no longer relevant, you can correct it, delete it, or mark it as not relevant. Memory sources may not show every factor that shaped a response, and we’ll keep improving this view to make it more comprehensive over time. Memory sources are rolling out on the web and coming to mobile soon.

These updates are designed to make personalization more useful while keeping you in control. Memory sources are only shown within your account experience, and if you share a chat, those sources are not shown in the shared chat. You can delete chats, use temporary chats that do not use or update memory or appear in history, turn off memory, disconnect apps anytime, and manage whether your content is used to help improve our models.

We’re rolling out GPT-5.5 Instant as ChatGPT’s new default model.

It replaces GPT-5.3 Instant for all ChatGPT users and improves everyday answers across accuracy, clarity and conciseness, image understanding, STEM questions, and when ChatGPT decides to search the web.

GPT-5.5 Instant is more factually reliable, especially for prompts where accuracy matters most. It also gives tighter, more direct answers without losing useful details, asks fewer unnecessary follow-up questions, and reduces clutter like overformatting and gratuitous emojis.

For Plus and Pro users using chatgpt on web, GPT-5.5 Instant can more effectively use context from past chats, files, and Gmail, when connected, to make responses more relevant. This can help ChatGPT tailor suggestions, pick up ongoing work, and reduce the need to repeat context across conversations.

GPT-5.5 Instant is rolling out starting today to all ChatGPT users. Paid users can continue using GPT-5.3 Instant for three months through model configuration settings before it is retired.

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.

Advanced Account Security in ChatGPT

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.

GPT-5.5 in ChatGPT

We’re rolling out GPT-5.5 in ChatGPT, our smartest frontier model yet for professional work. GPT-5.5 is built to understand complex goals, use tools, check its work, and carry more tasks through to completion.

GPT-5.5 is stronger at turning messy, multi-step requests into finished work. It can help write and debug code, research online, analyze data, create documents and spreadsheets, and move across tools until the work is done.

GPT-5.5 is also a major step forward for agentic coding. It performs better on complex terminal workflows, real-world GitHub issue resolution, and long-horizon coding tasks. It is better at holding context across large systems, reasoning through ambiguous failures, checking assumptions with tools, and carrying changes through the surrounding codebase.

The same capabilities also make GPT-5.5 more useful for professional knowledge work. It can find information, use tools, check outputs, and turn raw material into polished artifacts like documents, spreadsheets, slides, reports, research summaries, and plans. GPT-5.5 also performs strongly on search, retrieval, and document-grounded tasks, including multilingual and ambiguous queries and question answering across PDFs, reports, and policies.

GPT-5.5 Pro is available for the hardest questions and highest-accuracy work. Use it for tasks that require deeper reasoning, stronger structure, and higher confidence in the final answer.

GPT-5.5 Thinking is available in ChatGPT for eligible paid plans. GPT-5.5 Pro is available to Pro, Business, Enterprise, and Edu plans. For Enterprise and Edu workspaces, availability may depend on workspace settings.

Sometimes, you just want the right answer as quickly as possible. 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.

We’ll continue expanding Fast answers to more kinds of questions over time.

We’re launching ChatGPT for Clinicians, a free version of ChatGPT for verified clinicians in the United States. It’s designed to support real clinical work at the time of care, including evidence review, documentation, and medical research, with trusted clinical search, citations, reusable skills, deep research across medical literature, and support for earning CME credits on eligible clinical questions.

If you already have a ChatGPT account, you can use that same account to sign up. After signup, ChatGPT for Clinicians appears as a separate workspace under the same login, and your existing ChatGPT workspace remains available.

For more information, please see our help article ChatGPT for Clinicians or our blog post Making ChatGPT better for clinicians.

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.
