Hermes Agent is an open-source autonomous AI agent built by Nous Research, released under the MIT License. Its core philosophy: the longer it runs, the more capable it becomes.

What It Is

Unlike coding copilots tethered to an IDE or chatbot wrappers around a single API, Hermes Agent lives on your own infrastructure, maintains persistent cross-session memory, and features a built-in self-improving learning loop.

Tính năng chính

Closed Learning Loop
Autonomously creates and refines skills from experience; cross-session memory recall via FTS5 full-text search with LLM summarization; deepens its model of the user over time through Honcho user modeling.

Runs Anywhere — Not Just Your Laptop
Six execution backends: local, Docker, SSH, Daytona, Singularity, and Modal. Deployable from a $5 VPS to a GPU cluster; Daytona/Modal serverless options cost nearly nothing when idle.

15+ Platforms, One Gateway
A single gateway process connects CLI, Telegram, Discord, Slack, WhatsApp, Signal, Matrix, Email, SMS, DingTalk, Feishu, WeCom, and more — pick up any conversation from any platform seamlessly.

Parallel Subagents & Delegation
Spawns isolated subagents for concurrent workstreams; programmatic tool calling via `execute_code` collapses multi-step pipelines into single inference calls.

47 Built-in Tools + MCP Extension
Full web control — search, scraping, browser automation, vision, image generation, and TTS — plus support for any MCP server to extend capabilities further.

Open Skills Ecosystem
Skills are portable, shareable files compatible with the [agentskills.io](https://agentskills.io) standard, with community contributions available through the Skills Hub.

Research-Ready
Batch processing, trajectory export, and RL training via Atropos — built and maintained by the team behind the Hermes, Nomos, and Psyche model families.

Model Compatibility

Works with Nous Portal, OpenRouter (200+ models), OpenAI, or any custom endpoint. Switch providers with a single command — no code changes, no vendor lock-in.
