OpenAI says ChatGPT’s memory feature is getting smarter and coming to free users

OpenAI announced that ChatGPT’s memory feature, which learns user preferences over time, is receiving a more advanced "dreaming" system that improves context retention and accuracy. The upgraded memory will roll out to Plus and Pro users in the US starting today, while free users will gain access to the feature for the first time in the coming weeks after a fivefold reduction in computing costs.

ChatGPT’s memory feature allows it to learn about you and remember your preferences over time. Memory gives ChatGPT useful context for natural interactions that don’t need start from scratch each time. OpenAI has released new details on how ChatGPT’s memory feature is getting smarter and coming to free users for the first time.

ChatGPT memory generation is getting more advanced #

First, OpenAI explains how ChatGPT’s “dreaming” feature that helps fill in the blanks around memories automatically is getting an upgrade.

“Today we’re beginning to roll out a more capable and scalable system for synthesizing memory, developed to tackle the staleness, correctness, and scalability challenges that we observe when memory is applied to the hundreds of millions of users and multi-year time horizons in ChatGPT,” the company says.

Here’s how OpenAI says they’re supercharging ChatGPT memory now:

Today, we are launching a significantly more capable and compute-efficient memory architecture built on top of dreaming.

The memories synthesized by dreaming are reviewable through a summary of them made visible in the memory summary page. From the memory summary, you can quickly glean the highlights of what ChatGPT knows about you, add or update information about yourself, and provide instructions on what topics ChatGPT should bring up and when. If you want to drill down into a particular area to learn more, just chat with the model.

The company’s detailed blog post includes a collection of examples that show the improvements they aim to achieve. This includes three areas of focus:

  • Carrying forward useful context.
  • Following preferences and constraints
  • And staying current with the passage of time.

You can learn much more about how these are improving with today’s memory upgrade here.

OpenAI says Plus and Pro users in the US will start seeing the upgraded memory system starting today. The company is also doubling the capacity for memory storage.

ChatGPT is bringing dreaming-based memory to free users #

Additionally, OpenAI says its memory implementation has improved since launching enough now that it can efficiently offer the feature to free users for the first time.

“While dreaming-based memory has been available to Plus and Pro users for some time, we are only now able to offer Free users a version that meets our quality bar and is practical to serve at scale,” OpenAI says.

“Recent improvements reduced the compute required to serve dreaming to Free users by approximately 5x, making it possible to begin rolling out dreaming to Free users over the coming weeks and to increase memory capacity for Plus and Pro users.”

This means free users will start to see similarly enhanced memory and context in ChatGPT as subscribers have already enjoyed.
