Hermes Agent is a self-hosted, model-agnostic AI agent that features a unique self-improving learning loop to build persistent memory and reusable skills over time.
Unlike stateless chatbots, it autonomously extracts skills from your workflows and refines them, allowing the agent to become faster and more capable the longer it is used.
