Memories can also be retrieved with semantic search for RAG-based memory approaches where a developer may want to only insert relevant historical messages into the context window.

The AI Memory SDK automatically builds rich memories about users and topics that evolve and grow over time. This "learned context" can be easily injected back into your system prompt to enable seamless conversation across different models providers and context window compaction.

Using the AI Memory SDK, you can add long-term memory and deep personalization to any agent. Memories are continuously generated, edited, and rewritten by subconscious memory agents, running asynchronously in the background. Powered by our recent research on sleep-time compute.
