June 13, 2025 — Improvements to the ChatGPT search response quality

We’ve upgraded ChatGPT search for all users to provide even more comprehensive, up-to-date responses. In testing, we found users preferred these search improvements over our previous search experience.
Improved quality
Smarter responses that are more intelligent, are better at understanding what you’re asking, and provide more comprehensive answers.Handles longer conversational contexts, allowing better intelligence in longer conversations.
Improved search capability and instruction following
More robust ability to follow instructions, especially in longer conversations, significantly reducing repetitive responses.Capability to run multiple searches automatically for complex or difficult questions.Search the web using an image you’ve uploaded.
Known limitations
Users may notice longer responses with this new search experience.In some cases, a “chain of thought” reasoning will show up unexpectedly for simple queries. A fix for this is rolling out to users shortly.ChatGPT may still make occasional mistakes - please double check responses.

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

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 →
