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

Background

OpenAI is rolling out significant enhancements to ChatGPT’s memory feature, especially for free‑tier users.

• April 2024: OpenAI shipped its first memory feature, then called saved memories. It required explicit cues from the user (e.g., a direct prompt to remember a fact) and became less relevant over time.
• Subsequent year: Development of a new feature dubbed dreaming, which runs in the background and synthesizes information from many conversations without explicit instructions.

OpenAI explains that dreaming “supplemented saved memories to create a step‑function improvement in ChatGPT’s ability to personalize responses and offset the staleness of saved memories,” though it was never sufficient as a standalone memory system.

New Memory Architecture

The latest release introduces a revamped memory architecture built on the dreaming process. Key aspects include:

• Memory summary: As ChatGPT synthesizes information about you, it creates a readable “memory summary.” You can add, update, or delete details and specify when the model should reference them.
• Memory sources: Integrated with the memory summary, sources let you see the information used to personalize an answer and edit or delete that context. (See the related announcement alongside GPT‑5.5 Instant here.)

Benefits

• Greater visibility: Users can view and manage the data the model uses to personalize responses.
• Improved context carry‑over: For example, if you previously mentioned the camera you use, ChatGPT will consider that when recommending photography equipment.
• Better preference handling: Planning a trip? The model will draw on past travel conversations to tailor suggestions, such as recommending street‑photography spots in Singapore.
• Automatic memory revision: Memories are updated over time, preventing outdated references (e.g., treating a past trip as an upcoming one).

Rollout

• Plus and Pro users in the US: The new architecture is being rolled out today, offering greater memory capacity.
• Free accounts: Efficiency improvements will soon enable dreaming‑based memory recording for free users.
• International availability: The rollout will expand to other countries in the coming weeks.
