About Hermes Agent

Hermes Agent is an open source AI agent project from Nous Research, hosted as a GitHub repository written in Python. According to its homepage, the agent creates skills from experience, improves them during use, searches its own past conversations, and builds a model of the user across sessions. It can run on a low-cost virtual private server, a GPU cluster, or serverless infrastructure, and it can be reached from messaging apps while it runs on a cloud machine instead of a personal laptop.

Users can choose among several model providers, including Nous Portal, OpenRouter, OpenAI, and a custom endpoint, and switch models with the hermes model command. Use of any model depends on that provider's own terms and costs. Pricing for the project itself is not stated in the source.
