MIT-licensed personal and super-agent with persistent memory, messaging, schedules, subagents, and a learning loop.

ledger entry · observed by @whysanesanders

Hermes combines a broad personal-agent surface with better-than-average approval, pairing, file-safety, and sandbox controls. The learning loop and provider breadth are genuinely differentiated, but a default local terminal backend still shares the user's filesystem authority and the 64K context floor makes small local models a poor fit.

Best for

  • Provider-neutral personal agents with persistent memory and scheduled work
  • Telegram, Discord, Slack, WhatsApp, Signal, or email control of a remote agent
  • Operators who want local, Docker, SSH, or cloud sandbox backends

Requirements

  • Git; Linux also needs curl and xz-utils before the installer runs
  • A model with at least 64,000 tokens of context for agent tool use
  • At least one supported subscription, API provider, or local OpenAI-compatible endpoint

Security boundary

critical privilege

Selected terminal backend, Hermes state directory, messaging channels, and configured model/tool providers.

  • The default local backend has the same filesystem access as the operating-system user.
  • Keep smart or manual approvals enabled and use Docker or a cloud sandbox for untrusted tasks.
  • Pair messaging users, keep allowlists narrow, and never enable an allow-all gateway with terminal access.

Known limitations

  • A 64K model context is mandatory for agent tool use.
  • The broad feature set and provider matrix create a large configuration surface.
  • Smart approvals reduce accidental damage but are not a sandbox against a hostile agent.
  • Cloud-instance prices exclude inference and external tool charges.
