OpenAI expands ChatGPT memory to free users, doubles storage capacity for paid tiers

OpenAI announced June 4, 2026 that it is expanding ChatGPT's memory feature to free users for the first time while releasing an upgraded memory system for paid subscribers in the United States.

Compute efficiency gains enable free tier expansion

The company reduced the compute required to serve its "dreaming-based" memory system by approximately 5x, according to OpenAI's announcement. This efficiency improvement makes it practical to offer the feature to free users at scale.

Free users will receive access to the memory feature "over the coming weeks," OpenAI says. The system automatically tracks important details and preferences across conversations without requiring users to repeat context.

New memory architecture for paid users

Plus and Pro subscribers in the US began receiving access to a "more capable and compute-efficient memory architecture" starting June 4. The upgraded system addresses what OpenAI describes as "staleness, correctness, and scalability challenges" when serving hundreds of millions of users over multi-year timeframes.

The new architecture includes a memory summary page where users can review what ChatGPT knows about them, add or update information, and provide instructions on which topics the system should reference and when.

OpenAI is also doubling memory storage capacity for Plus and Pro users, though specific storage limits were not disclosed.

Three focus areas for memory improvements

The upgraded system targets three specific capabilities:

• Carrying forward useful context across conversations
• Following preferences and constraints set by users
• Staying current with the passage of time

Users who prefer the previous saved memories experience can revert to the legacy system through settings.

What this means

The 5x compute reduction represents a significant engineering achievement that directly enables product expansion—free users gain a feature previously limited to paying customers, while paid tiers get expanded capacity. The move also signals OpenAI's focus on long-term context as a competitive differentiator, particularly as memory becomes table stakes for conversational AI systems that millions use daily. The phased US-only rollout for paid tiers suggests the company is stress-testing the new architecture before global deployment.
