Hermes Agent

The agent that grows with you

Overview

About Hermes Agent

Hermes Agent is an open source personal agent from Nous Research that runs as a terminal application or a native desktop app on macOS, Windows and Linux, and reaches you through Telegram, Discord, Slack, WhatsApp, Signal, email and Home Assistant from a single gateway. The problem it goes after is that most agents are tied to one surface. An editor plugin knows your codebase but not your calendar, and a chat assistant forgets everything between sessions. Hermes keeps one memory behind every surface it runs on, so context built up in the terminal is still there when you message it from your phone, and a skill it learned last week is available on all of them.

The project describes its core as a closed learning loop: it curates its own memory, creates skills out of work it has already done, and builds a persistent profile of the person it works for, with full-text session search and model-written summaries over past conversations. Skills follow the agentskills.io open standard rather than a private format. There is no model lock-in - it runs against Nous Portal, OpenRouter, OpenAI or your own endpoint, and you switch with a single command. Nous sells an optional Portal subscription that bundles monthly credits and catalogue access, and the honest caveat is that the tier prices are behind sign-in even though per-model token rates are published openly. Development moves quickly and the release is still pre-1.0, with a very large open issue count, so treat it as a project you follow rather than one you set and forget.
