Hermes Agent

Overview

Hermes Agent is an open-source autonomous AI agent developed by Nous Research. Unlike traditional AI chatbots that only respond within a single conversation, Hermes Agent is designed to learn continuously, remember past interactions, automate complex workflows, and execute tasks across multiple platforms.
