Hermes Agent — Open-Source AI Agent with Persistent Memory

Open Source · MIT License · By Nous Research The AI agent that grows with you. Install it on your server, give it your messaging accounts, and it becomes a persistent personal agent — learning your projects, building its own skills, and reaching you wherever you are. Not a chatbot. Not a copilot. An agent that lives on your machine and gets smarter every day. 40+ Built-in Skills 5 Chat Platforms MIT License 100% Self-Hosted Everything You Need in One Agent Hermes Agent combines persistent memory, automated skill creation, and multi-platform reach into a single open-source package. Persistent Memory Remembers your preferences, projects, and environment across every session. The longer it runs, the better it knows you — no re-explaining context every time. Automated Skill Creation When Hermes solves a hard problem, it writes a reusable skill document so it never forgets how. Skills are searchable, shareable, and compatible with the agentskills.io open standard. Multi-Platform Gateway Connect Telegram, Discord, Slack, WhatsApp, Signal, and CLI — all from a single gateway process. Voice memo transcription, cross-platform continuation. Start a conversation on Telegram, pick it up in your terminal. Scheduled Automations Built-in cron scheduler with delivery to any platform. Set up daily reports, nightly backups, weekly audits, and morning briefings — all running unattended. Parallel Sub-Agents Spawn isolated sub-agents for parallel workstreams. Each gets its own conversation and terminal. Collapse multi-step pipelines into zero-context-cost turns via RPC. Full Browser & Web Control Web search, page extraction, full browser automation — navigate, click, type, screenshot. Plus vision analysis, image generation, text-to-speech, and multi-model reasoning. Powerful Capabilities Out of the Box From sandboxed code execution to real-time browser control — Hermes Agent handles it all.

Hermes Agent is an open-source autonomous AI agent built by Nous Research and released in February 2026. It's not a coding copilot tethered to an IDE or a chatbot wrapper around a single API. Hermes lives on your server, remembers what it learns, and gets more capable the longer it runs. It supports Linux, macOS, and WSL2 — with no prerequisites, installing everything automatically via a single curl command. Open source · MIT License · Built by Nous Research. All data stays on your machine. No telemetry, no tracking, no cloud lock-in. Built for MLOps & AI Training Beyond task automation — Hermes Agent is a platform for generating training data, running RL experiments, and exporting trajectories for fine-tuning. Batch Processing Generate thousands of tool-calling trajectories in parallel with automatic checkpointing. Configurable workers, batch sizes, and toolset distributions. RL Training Atropos integration for reinforcement learning on agent behaviors. 11 tool-call parsers for training any model architecture.
