November 12, 2025 — GPT-5.1 in ChatGPT

We’re updating GPT-5 to GPT-5.1 Instant and GPT-5.1 Thinking, making answers both smarter and more conversational. GPT-5.1 Instant now uses light adaptive reasoning for tougher questions while staying fast, and GPT-5.1 Thinking adapts its thinking time more precisely for complex tasks with clearer, less jargony responses.GPT-5.1 Auto continues to route each query to the best model, and GPT-5 models remain available for three months under the Legacy models dropdown so you can compare and transition at your own pace.GPT-5.1 Instant and Thinking are rolling out first to paid (Pro, Plus, Go, Business) users, then to free and logged-out users, with Enterprise and Edu getting a temporary early-access toggle; GPT-5.1 will also be available soon in the API as gpt-5.1-chat-latest (Instant) and gpt-5.1 (Thinking).

November 12, 2025 — New tone and personalization controls

We’re updating ChatGPT’s tone controls so it’s easier to make responses sound the way you prefer. You can now choose from updated presets like Default, Friendly, Efficient, Professional, Candid, and Quirky (with Cynical and Nerdy still available), and we’re experimenting with more granular controls over how concise, warm, or scannable responses are, plus how often emojis appear.Changes you make in Personalization now apply across all chats immediately (including existing conversations), and GPT-5.1 models follow your custom instructions and style preferences more reliably.

November 5, 2025 — Interrupt ChatGPT

You can now interrupt long-running queries (such as deep research or GPT-5 Pro) to refine what you’re asking—no restart required or progress lost. For example, if you're researching the perfect bookshelf and suddenly remember that your wall is 72" wide and you can't drill into it, you can simply add that information midstream by clicking “update” in the sidebar and sending the new information as a message. The model will adjust its approach based on your new requirements.

Tracking what they’re building

Observed site activity — new pages appearing on each platform’s website, updated daily.

What is the LLM Changelog?

The LLM Changelog is a live, automated tracker that monitors release notes and documentation updates across the largest AI platforms — including OpenAI's ChatGPT, Google's Gemini, Perplexity AI, Microsoft Copilot and Google Search. Changes are crawled daily and presented in a single, searchable feed.

Why AI Platform Changes Matter for Brands

When AI models update their training data, adjust ranking signals or change how they cite sources, the brands and products they recommend can shift overnight. An API change to Gemini or a new feature in ChatGPT can alter which businesses get mentioned in millions of AI-generated responses.

Platforms We Track

We currently monitor ChatGPT release notes, OpenAI developer and model changelogs, Gemini API and app updates, Perplexity product and API changes, Microsoft 365 Copilot release notes, and Google Search Central documentation updates. New sources are added as the AI landscape evolves.

Built by reconnAI
