ChatGPT can now more reliably find information from your earlier conversations. If you are a Plus or Pro subscriber, you can now search through your entire chat history, all the way back to when you first created your account, and ask questions that refer to anything you’ve talked about before.
ChatGPT does store your chat history, and you can search it manually, but the feature has been unreliable. It often struggles to surface the right conversation, especially when you have multiple similar threads.
This update, called PersonalContextAgentTool in the system, helps ChatGPT fetch details from past conversations. That means you no longer have to manually dig up older chats when you want help with something like a recipe you asked about weeks ago or a workout plan you drafted months back.
The new history reference works a bit like click-through sources. When ChatGPT uses something from an old chat to answer your question, it shows that earlier chat as a clickable source you can open and review. That gives you confidence about where a detail came from and lets you go back to the original context if you want.
While this is a welcome upgrade for ChatGPT users, it does arrive relatively late. Google’s Gemini introduced the ability to reference past conversations back in February 2025, meaning Gemini users have already been enjoying more context-aware, continuous chats for some time now.
Nevertheless, OpenAI has been working to evolve ChatGPT with major model upgrades, including the rollout of GPT-5 and a follow-up ChatGPT-5.1 release that adds new personalities, a warmer tone, and quicker replies.
For ChatGPT Plus and Pro users, this history search feature represents a leap forward in how personal and context-aware makes the experience. Instead of treating each chat in isolation, the system now stitches together threads of your past conversations in a way that feels more like talking to a human who remembers what you said before.

Google Research suggests AI models like DeepSeek exhibit collective intelligence patterns
The paper, published on arXiv with the evocative title Reasoning Models Generate Societies of Thought, posits that these models don't merely compute; they implicitly simulate a "multi-agent" interaction. Imagine a boardroom full of experts tossing ideas around, challenging each other's assumptions, and looking at a problem from different angles before finally agreeing on the best answer. That is essentially what is happening inside the code. The researchers found that these models exhibit "perspective diversity," meaning they generate conflicting viewpoints and work to resolve them internally, much like a team of colleagues debating a strategy to find the best path forward.
