type: concept title: synthesis layers

synthesis layers

A pattern in memory-systems that composes retrieved chunks into higher-order summaries before they reach the agent.

Deployed at [[companies/ridge-platform]] and studied by [[people/alice-example]]. Compare to [[concepts/hybrid-retrieval]] and builds on [[concepts/agent-memory]].

Notes

Synthesis layers reduce token budget by pre-fetching a synopsis. Reference work in [[concepts/hybrid-retrieval]] demonstrates the retrieval side of the same idea.
