Every update to ChatGPT, Gemini, Perplexity, Copilot and Google Search can change how your brand appears in AI-generated answers. We track release notes, API changes and documentation updates across major LLM platforms so you don't have to.
We’ve changed our context window functionality to enable infinite-length conversations (with some exceptions) and significantly reduce length limit errors by summarizing earlier messages when a chat approaches its context limit. Read more here:Understanding Usage and Length Limits.
Claude in Chrome is now available in beta to all Max plan subscribers. After months of testing, we're expanding access with the following updates:
Scheduled tasks: Set recurring browser tasks to run automatically on your schedule. Set it once and Claude handles it from there.Follow a plan: Approve Claude's plan, then let it execute the entire workflow independently within those approved boundaries, without asking for permission until it's done.Model selection: Choose between Haiku 4.5 for speed, Sonnet 4.5 for complex tasks, or Opus 4.5 for maximum reasoning power—switch anytime based on what you need.
We released our fastest, most cost-efficient model – Claude Haiku 4.5. Our latest small model matches Sonnet 4’s performance on coding, computer use, and agent tasks.
Powered by Haiku 4.5:Claude in Chrome now defaults to Haiku 4.5 so it’s a faster, more responsive experience. You can always switch back to Sonnet 4.5.Claude handles image uploads for you:Give Claude an image and tell it where to upload, whether it’s an expense report, form attachment, or a picture upload.Show Claude exactly what you mean:Take a screenshot or drag to highlight specific parts of your screen. Point Claude to the exact button, field, or detail—much faster than describing complex layouts in words.
We released our newest model, Sonnet 4.5. This is the best model in the world for real-world agents, coding, and computer use. Read our blog post here:Claude Sonnet 4.5.
Pro users can now leverage Claude’s file creation and editing capabilities, and users on all paid plans can access these features on Claude for iOS or Android. See this updated article for more information:Create and edit files with Claude.
The remaining Max users on our waitlist were granted access to Claude in Chrome, along with the following updates:
Powered by Sonnet 4.5:Claude in Chrome now defaults to Sonnet 4.5, our smartest model yet. Improved for browser tasks, you'll notice better reasoning, fewer errors, and more reliable task completion—especially for multi-step workflows.Work across multiple tabs:Claude can now juggle multiple browser tabs at once. Just drag tabs into Claude's tab group and it can see and work across all of them simultaneously—no more jumping back and forth to gather information before taking action.Smarter on the sites you use every day:Claude now understands how to navigate Slack, Google Calendar, Gmail, Google Docs, and GitHub without you having to direct every click. Ask Claude to "schedule a meeting" or "update the doc" and it knows what to do—no need to walk it through every step. We’re continuing to improve Claude’s understanding of other popular sites.Get notified when Claude needs you:Turn on notifications and Claude will ping you when it needs your permission or when a task is complete. Now you can switch to other work while Claude handles things in the background.Show Claude exactly what you mean:Upload images or take screenshots of specific screen areas to give Claude precise visual context. Much faster than describing what you're looking at.

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
reconnAI tracks how AI systems represent brands in their responses. We monitor mentions, sentiment and citations across ChatGPT, Gemini, Perplexity and more — helping businesses understand and improve their visibility in the age of AI search. Learn more →
