OpenAI is introducing a major upgrade to ChatGPT's memory capabilities, allowing the AI to retain all previous conversations indefinitely. CEO Sam Altman described the development as a step toward making ChatGPT a more personalised assistant that better adapts to users over time.

Previous versions of the AI could only remember chats from the past few weeks, which helped with ongoing projects and stylistic consistency.

The new update goes much further, enabling ChatGPT to recall details from all prior conversations and use them to offer more tailored support, such as giving lifestyle advice or acting as a personal coach.

The feature will initially roll out to ChatGPT Plus and Pro subscribers, with broader availability likely in the future. However, the move has sparked some concerns around privacy, as the AI's enhanced recall could allow anyone with account access to uncover personal details with a simple prompt.

Users may wish to take precautions, such as setting up custom instructions to limit the disclosure of sensitive information.
