Why does my custom GPT forget everything between chats?
A custom GPT's instructions and supplied knowledge are not a personal memory carried between your conversations. The support reply describes those conversations as stateless.
In community thread 1059182, an OpenAI Support reply on 7 March 2026 says memory is not currently supported in Custom GPTs, conversations with a Custom GPT are still stateless, and Projects are probably the best workaround for now.

What will GPT memory look like when OpenAI rolls it out?
This is OpenAI's described future behaviour, not a capability available today.
OpenAI says memory has not yet rolled out for GPTs. When it does, builders will be able to enable it, you will need Memory on, each GPT will have its own memory that is not shared with ChatGPT or other GPTs, and builders will not see your memories.

What works instead today?
Choose where the context should live and who should hold it. These options do not make custom GPT memory available.
| Option | Where context lives | Limits and evidence |
|---|---|---|
| Projects | In the project, rather than a custom GPT. | In community thread 1059182, an OpenAI Support reply on 7 March 2026 says memory is not currently supported in Custom GPTs, conversations with a Custom GPT are still stateless, and Projects are probably the best workaround for now.

Project sharing is available to all ChatGPT users. Once a project is shared, project-only memory turns on automatically and cannot be switched back, and shared projects do not have access to any individual member's context. Free users can invite up to 5 collaborators. OpenAI Help Centre: Projects in ChatGPT. Verified . |
| Knowledge files in the GPT | In files uploaded by the builder. | Fixed until the builder re-uploads them. This is supplied reference material, not personal memory learned between chats. |
| Actions to the builder's own API | The builder stores context in their own service. | You trust the builder's storage and access rules. An Action is not ChatGPT memory. |
| External memory through MCP | In the external memory, connected to a normal ChatGPT chat, not inside a custom GPT. | Full MCP support, including write actions, is a beta for Business, Enterprise and Edu on ChatGPT on the web. Pro can connect MCP servers with read and fetch permissions in developer mode. Web only. Not available on Plus or Free. OpenAI Help Centre: Developer mode and MCP. Verified . |
Can I use AI Twin with ChatGPT?
AI Twin connects through MCP at https://ai-twin.app/mcp, not through a custom GPT Action. This connects AI Twin to ChatGPT itself; it does not claim a connection inside a custom GPT.

get_brief: Returns your most recent Brief.
list_key_dates: Returns your upcoming key dates.
propose_to_twin: Suggests something for your Twin to remember. It lands in your review queue. Nothing is saved until you confirm.

Is my custom GPT conversation shared with the builder?
The memory help page says builders will not see your memories when GPT memory arrives. That is a statement about memories, not a promise about data you send to a builder's own API through an Action. Check that service's storage and privacy terms before sending context.

When it does, builders will be able to enable it, you will need Memory on, each GPT will have its own memory that is not shared with ChatGPT or other GPTs, and builders will not see your memories.
