ChatGPT's memory is getting better, especially if you're on the free tier

Article excerpt

OpenAI has upgraded ChatGPT's memory systems, with free-tier users seeing the biggest gains. The company significantly improved the chatbot's "dreaming" architecture, the underlying technology that helps the model retain and recall information across conversations. The enhancement means casual users now get better continuity when they return to previous chats, while paid subscribers benefit from more refined recall overall. OpenAI didn't announce specific technical details, but the rollout represents a competitive move as AI assistants increasingly focus on personalization and context retention.
