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).

Explainable AI with deep and inline citations for connectors
Microsoft Copilot introduces an explainable AI experience that shows how responses from connected data sources are generated by using inline and deep citations.
Details:
What changed:
Copilot now provides inline citations for connector-based results, with a hover experience that displays a glance card summarizing the cited entity, and a deep citation view available when users select the citation for more detail.
Why:
Users want clearer insight into how Copilot-generated results are created, especially when responses are based on external or connected data sources. This update improves transparency by explaining the origin of information through richer citation details.
Try this:
Hover over an inline citation in a Copilot response to view a summary of the referenced entity.
Select the citation to open a detailed view that explains how the result was generated.
Why this matters:
Business impact:
Improves trust and confidence in Copilot responses by making data sources and reasoning more transparent for teams using connected systems.
Personal impact:
Helps individuals better understand and validate Copilot results by clearly showing where information comes from and how it was used.

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.

Declarative agents upgraded to GPT‑5.1
Microsoft 365 Copilot declarative agents now use the GPT‑5.1 model with automatic model selection for performance and reasoning.
Detailes:
What changed:
Declarative agents now run on GPT‑5.1 using “auto” architecture, which selects the best model (fast or reasoning‑optimized) based on the user’s prompt. This improves speed and quality. Note that as the agent uses the "Think deeper" mode to generate higher quality responses, users will experience a slightly higher latency.
Why:
The upgrade ensures declarative agents provide more accurate and detailed responses.
Try this:
Use a declarative agent to process complex queries.
Test scenarios that require fast responses versus deeper reasoning.
Why this matters:
Business impact:
Supports higher‑quality automation and decision‑making.

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.
