ChatGPT gets big memory boost, OpenAI says it will remember everything about you now

OpenAI has unveiled a new ChatGPT memory architecture built on its dreaming system. The update is meant to improve long-term context and give users more control over remembered details.

In Short

• OpenAI upgrades ChatGPT's memory with a new architecture
• Users get more visibility into what ChatGPT remembers
• Memory summaries can now be reviewed and updated

If you're a regular ChatGPT user, you've probably noticed how useful its memory feature can be. Instead of treating every conversation as a completely new interaction, ChatGPT can remember certain details about you and use them to provide more tailored responses. That means it can learn your preferences, ongoing projects, and personal constraints, allowing future conversations to start from a shared context rather than from scratch.

Now, OpenAI is making that experience even better.

The company has announced a major upgrade to ChatGPT's memory system. It has introduced what it describes as a more capable and compute-efficient memory architecture built on top of a technology called "dreaming."

The goal is to address some of the biggest challenges associated with AI memory, including staleness, correctness, and scalability.

How ChatGPT's memory has evolved

Before going into details of what has improved, here is a little context for you. OpenAI first introduced memory in April 2024, allowing users to ask ChatGPT to remember information and carry it forward into future conversations. The feature received a significant upgrade in April 2025, when ChatGPT gained the ability to reference context from past chats beyond the saved memories list.

That update marked the initial version of "dreaming," a background process that allows ChatGPT to learn from many conversations and synthesise its memory state so it can provide the most relevant context when users return.

Now, OpenAI says it has taken the next step by building a new memory architecture on top of that foundation.

What does the new update mean for users?

According to OpenAI, the new system is better at carrying context forward over time.

Imagine you're planning a trip to Singapore. Two months before the trip, you ask ChatGPT to help build an itinerary. Because it already remembers details from previous travel conversations, it may know that you enjoy wildlife photography, prefer hotels with strong air conditioning, and would rather have a quiet dinner than spend the evening in a crowded bar.

Instead of starting from zero, ChatGPT can use that context to provide more personalised suggestions. The idea is to make interactions feel less like separate conversations and more like an ongoing relationship where useful context is preserved.

Users get more control over memory

The update is not just about helping ChatGPT remember more. OpenAI is also giving users greater visibility into what the chatbot knows about them. The memories synthesised through dreaming can now be reviewed through a memory summary page.

This summary allows users to quickly see the key details ChatGPT has learned over time, update information, add new details, or provide instructions about what topics the AI should bring up and when. If users want to explore a particular memory in more detail, they can simply chat with the model.

The new memory architecture is available to Plus and Pro users in the United States starting today. OpenAI says it will expand the feature to additional countries and to Free and Go users over the coming weeks.
