# Hermes Agent

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.

## 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.

### Execution Environments

### LLM Providers

### Skills System

### Security & Privacy

## What Is Hermes Agent?

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.

### Trajectory Export

Export conversations in ShareGPT format for fine-tuning. Trajectory compression fits training data into token budgets.

## Get Started in Minutes

No prerequisites. Works on Linux, macOS & WSL2. Installs everything automatically.

### Install

Installs uv, Python 3.11, clones the repo, sets up everything. No sudo needed.

### Configure

Connect to Nous Portal (OAuth), OpenRouter (API key), or your own endpoint. Interactive setup wizard.

### Start Chatting

Full interactive CLI with tools, memory, and skills. That's it.

### Go Multi-Platform (Optional)

Walk through connecting Telegram, Discord, Slack, or WhatsApp. Runs as a systemd service.

### Keep It Up to Date

Pulls the latest changes and reinstalls dependencies. Run anytime to get new features and fixes.

⚠️ Native Windows support is experimental. Please install WSL2 and run Hermes Agent from there.
