Why it matters

Provides stateful conversation APIs for applications. ChatGPT memory is a separate product feature; neither should be described as persistent memory in the underlying model weights. OpenAI's release notes add memory sources on all consumer plans (5 May 2026), which show saved memories and past chats that may have shaped a response, and a memory summary page (in place by June 2026); since 12 June 2026 its Delete and turn off memory control removes what it lists. OpenAI notes that sources may not show every factor behind a response.

Continuity layer — this site’s working definition: A continuity layer is the part of an AI system that carries forward governed state across sessions, tools, models, and hosts: what is currently true, what changed, why it changed, by whose authority, and which evidence supports it. It sits above memory and retrieval, and below agent execution, turning stored history into usable, auditable continuity; and it can correct, supersede, revoke, expire, and forget what it carries, with evidence that it did.
