ChatGPT Upgraded: Access Past Conversations More Reliably for Plus and Pro Users

• OpenAI has rolled out an update for ChatGPT Plus and Pro subscribers, allowing the AI to more reliably surface information from entire chat histories.
• The update, internally named PersonalContextAgentTool, enables ChatGPT to respond to prompts referencing any past conversation, even those dating back to account creation.
• Users no longer need to manually search; ChatGPT can now retrieve details like a recipe from weeks ago or a fitness routine from months prior.
• A key feature is increased transparency: when ChatGPT uses past information, it provides a clickable reference to the original chat for context and verification.
• This update significantly improves user experience for long-term users, positioning ChatGPT as a personal knowledge base, though competitors like Google Gemini introduced similar features earlier.

Why It Matters: ChatGPT now reliably accesses full chat history, enhancing user experience and transparency for Plus/Pro subscribers.
