Hermes Agent v0.22 is an open-source, self-improving AI agent from Nous Research that runs wherever you work: a terminal, a desktop app, or messaging apps like Telegram, Discord, Slack, and WhatsApp. Tagged the Threshold Release on October 13, 2026, it is built for developers and power users who want an assistant that learns from its own solved tasks.
Core Features
- Self-improving loop: it writes reusable skills after solving a problem, so repeat tasks get faster and cheaper.
- Keyless first-run setup via the free nous/welcome trial model, with no API key needed to start.
- 600-plugin catalog covering tools, desktop panes, memory, model providers, and voice.
- Connectors for Gmail, Linear, and Notion through the Nous tool gateway.
- One-click local llama.cpp models with automatic GPU and RAM fitting.
Use Cases
- Developers who want an agent that recalls past solution paths across sessions.
- Privacy-focused users running local models so nothing leaves the machine.
- Teams wiring the agent into Gmail, Linear, or Notion without a full platform account.
Pricing
Hermes Agent is MIT-licensed and free to use; you pay only for the model you connect, whether that is a cloud provider or a local llama.cpp build. The repo sits near 219k GitHub stars.
Our Take
Best for technical users who want a customizable, local-first agent; the trade-off is setup depth that casual users may find heavy versus closed assistants like ChatGPT. Browse other AI chat tools.
