About Hermes Agent
Hermes Agent is a desktop AI agent developed by Nous Research that maintains persistent memory and self improving capabilities across sessions and platforms. It operates as a local first, cross platform interface for LLMs, integrating with multiple model providers and deployment environments without vendor lock in. The agent implements a closed learning loop where it curates its own memory, creates and refines skills from experience, and supports cross session recall via full text search and summarization.
