Zep

Zep - A long-term memory store for LLM applications.

Zep stores, summarizes, embeds, indexes, and enriches conversational AI chat histories, and exposes them via simple, low-latency APIs.

  • Long-term memory persistence, with access to historical messages irrespective of your summarization strategy.
  • Auto-summarization of memory messages based on a configurable message window. A series of summaries are stored, providing flexibility for future summarization strategies.
  • Vector search over memories, with messages automatically embedded on creation.
  • Auto-token counting of memories and summaries, allowing finer-grained control over prompt assembly.
  • Python and JavaScript SDKs.
