Cortex
Semantic memory infrastructure for multiple models and agents
About Cortex
Cortex is semantic memory infrastructure for models and agents. It retains decisions, context, and sources across chats so multiple AIs can share the same memory. Its quality gate filters stored content and rejects about eight in ten requests in production to remove redundant content. Users can enable it in the official ChatGPT connector directory or connect Claude and other AI through MCP; memories can be exported or deleted on request, with unlimited search and recall.
