LLM Changelog

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.

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 If something is outdated or no longer relevant, you can correct it, delete it, or mark it as not relevant.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.

GPT-5.4 is OpenAI's latest model combining improved reasoning, coding, and agentic capabilities, with a "Thinking" mode that shows its reasoning upfront so users can redirect it mid-response.
For brand visibility, the two most relevant changes are that better deep web research could favour brands with stronger recent citation footprints, and improved context retention may mean brand associations are held more consistently across longer conversations.

A minor polish update to ChatGPT focused on feel rather than capability - more accurate answers, better web search results, and a more natural conversational tone with less unnecessary hedging and filler. Essentially OpenAI tuning the day-to-day experience based on user feedback rather than chasing benchmark scores.

Projects now make it easy to build a living knowledge base by adding sources wherever your context already lives; from apps, conversations, or quick text inputs.
Sources from apps:Paste a link to a Slack channel or Google Drive file or folder to add it directly as a project source.Additionally, use connected apps directly in chats.Sources from chats:Save useful ChatGPT responses into your project so great outputs become reusable knowledge.Ad-hoc text sources:Paste notes, briefs, or reference material directly to capture context instantly.

We’re making an update to GPT-5.2 Instant in ChatGPT and the API that improves response style and quality.Users should notice responses that are more measured and grounded in tone, in a way that’s more contextually appropriate to the conversation. The model also tends to output clearer, more relevant answers to advice-seeking and how-to questions, more reliably placing the most important info upfront.

We’re beginning to roll out a test for ads in ChatGPT in the U.S. for logged-in adults on the Free and Go tiers. Plus, Pro, Business, Enterprise, and Education plans do not have ads. The test will be a subset of users to start. We will expand over the coming weeks as we learn from this test.ChatGPT’s answers are generated independently from advertising. Answers are optimized based on what’s most helpful to you. When you see an ad, they are always clearly labeled as sponsored and visually separated from the organic answer.Ads are shown using information that stays within ChatGPT and is not shared with advertisers. This includes what you’re discussing, how you interact with ads (such as ads you hide or engage with), and your past chats and memories, if you have ads personalization enabled. You’re in control of this experience: you can dismiss ads, share feedback, learn how and why you’re being shown an ad, delete your ad data with one tap, and manage ad personalization at any time.Advertisers never see your chats or personal details and receive only aggregated performance information, like impressions and clicks. During the test, ads do not appear in chats about sensitive topics or regulated topics, including health, mental health, or politics, and are not shown to users who tell us or we predict are under 18.

Jan 10, 2026:We lowered the Standard and Light thinking time as we observed users prefer faster responses. As part of this update, theExtendedthinking setting for GPT-5.2 was unintentionally changed to be lower which we have now fixed.February 3, 2026:We made another small reduction to Standard thinking time based on testing.February 4, 2026:We’re restoring theExtendedthinking level for GPT-5.2 Thinking to its prior setting, correcting the inadvertent reduction from January. Extended is now back to its prior level.We periodically adjust the default thinking time for our reasoning models. These changes are based on ongoing experiments to find the best balance between answer quality and response speed for users.Thethinking level toggleintroduced in September 2025 gives users more choice beyond Standard, allowing them to select the right thinking level for their question—whether they want lighter, faster responses or more extended reasoning when depth and accuracy matter more.Thinking time is not directly comparable across different models. Each model is tuned independently to what works best for users. We’ll continue to adjust these settings as models evolve, and will keep giving users clear controls when there are meaningful tradeoffs to choose from.

Responses in ChatGPT are now more visual and easier to scan.For everyday questions, responses may include at-a-glance visuals—like checking your team’s latest stats, converting units, or doing a quick calculation.Answers now also highlight important people, places, products, and ideas. You can tap any highlight to open a side panel with key facts and trusted sources, making it easy to understand the context without asking follow-up questions.Rolling out globally on iOS, Android, web.
