Agent memory.

We study the primitives of agent cognition: how should an agent decide what to remember, when a memory has become stale, and how to retrieve the right context for a given task.

Our research informs our products directly — every pipeline stage in Brain exists because we could not find a satisfactory answer in the existing literature.

Memory layer · v0.1 · 2026

· 7-stage write pipeline

· 5-retriever hybrid read

· Typed schema (fact/preference/event/entity/relation)

· Purpose-built Rust storage engine (vector arena + WAL + redb + HNSW + tantivy)

Typed, temporal-aware memory layer. Seven-stage write pipeline rejects noise before storage. Five-retriever hybrid search fuses semantic, keyword, graph, temporal, and type signals via RRF.
