LLM/AI Changelog

We’re updating GPT-5.5 Instant, our most-used model in ChatGPT, to improve conversational quality—especially when users are making a decision, asking for advice, planning something, researching options, or shopping.The model is better at identifying the underlying goal behind a question and carrying context across multiple turns. It also follows complex instructions more reliably: when a request includes several constraints or requirements, responses are more likely to address all of them and clearly explain why a recommendation is a good fit.When users add constraints, clarify what they mean, or push back on an answer, the model should adapt more effectively instead of repeating its original approach.Shopping and local business queries should also feel more useful. The model makes better use of location context to surface relevant nearby options and can bring together product recommendations, business information, and images more coherently when those elements are helpful.Overall, responses should feel more tasteful and cohesive. Formatting is less templated and more intentionally designed, with greater creativity alongside better restraint.

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.

Lockdown Mode is now available to all logged-in users across account types and workspaces. It is an optional opt-in advanced security setting that limits access to the web and external services to help reduce the risk of data exfiltration from prompt injection attacks.When Lockdown Mode is on, ChatGPT restricts network-enabled capabilities such as live web browsing, deep research, agent mode, file downloads, and some web-derived image support. Personal users can turn it on from Settings > Security. Workspace admins can configure access for members through workspace settings and role-based access controls.Learn more:Lockdown Mode

We’re updating GPT-5.5 Instant in ChatGPT and the API to improve response style and quality. It’s now easier to read, more natural in everyday conversations, and better paced in practical help tasks, with fewer overly long or bullet-heavy responses.With this update, canvas will no longer be available in GPT-5.5 Instant or GPT-5.5 Thinking. Writing and coding functionality is now supported directly in chat responses through writing blocks and code blocks. Paid users can continue using canvas for a limited time through legacy models until those models are sunset.

We’re starting to roll out a new personal finance experience in ChatGPT.  Pro users in the United States can securely connect supported financial accounts, see a dashboard of where their money is going, and ask questions grounded in their financial context.Available on web and iOS, Finances lets you view spending, bills, subscriptions, net worth, and investment information in one place. You can ask questions directly in ChatGPT or use the Finances page to explore insights, review upcoming payments, track recurring charges, and think through budgets, savings goals, debt payoff, and other financial decisions.Users can connect accounts through Plaid. This experience is rolling out gradually, so some eligible users may not see it right away.ChatGPT can help users understand and plan, but it cannot move money, pay bills, place trades, file taxes, or act as a financial, legal, tax, or investment adviser.

What
: Added a new guide on
optimizing for generative AI features
on Search. Notable new sections include guidance on the importance of providing non-commodity content,
tips about providing local, shopping, image, and video content, mythbusting common "AEO/GEO"
misconceptions, initial guidance on AI agents, and more information on why SEO best practices
continue to be relevant for success in our generative AI features on Search.
Why
: To help site owners, SEOs, and developers better understand how to optimize
their content for appearance in generative AI features on Search, and what they can ignore.

Free users in ChatGPT will now see more inline images from the web to help make visual topics easier to understand, including well-known people, places, and products. When visuals can add clarity, images may appear alongside relevant parts of an answer. You can click any image to view it at its original size and see source attribution.This is rolling out globally on web and iOS to Free users for responses using 5.5-Instant.

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.

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 launchingChatGPT 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 articleChatGPT for Cliniciansor our blog postMaking ChatGPT better for clinicians.
