Product Release

Opensource Native Memory for Hermes Agent (4k+ stars)

⚡ TL;DR:

  • Proven in Production: Built on the Top memory system for OpenClaw (30K+ downloads in week 1)

  • Long-running Precision: >92% retrieval accuracy across long-running sessions, best proven in the market so far → Real-production benchmark on LongMemEval

  • Fast: ~1.6s average retrieval. Most queries never need an LLM round-trip.

  • Fully local by default, with optional cloud-sync for teams.

Hermes Agent (built by Nous Research) stands out with its self-improving, stateful "mind-like" architecture. Instead of just orchestrating tools around a stateless LLM, it treats the agent as something that grows and compounds intelligence over time.

ByteRover is now live in Hermes Agent memory. By integrating ByteRover, you give Hermes a native & persistent memory layer that can recall exact memory based on your prompts even when the knowledge spreads for years:

  • Persistence even in long-running sessions: Make Hermes fully long-term capable, maintaining >92% retrieval accuracy across long-running sessions because the architecture itself tells the agent what’s relevant before the model even starts thinking.

  • Highly accurate & Human-controllable Context: ByteRover’s structured file-based system allows Hermes to retrieve exact historical logic, not just similar text. You can inspect, edit, and trust what your agent knows.

  • Token costs saving: Hermes can focus its compute on reasoning while ByteRover handles the heavy lifting of context curation, saving 50-70% token costs on average.
