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.

About moltis
Moltis is a secure persistent personal agent server written in Rust and released under the MIT license. It lives in the Rust AI agent and self hosted assistant ecosystem, and it presents itself as one binary that runs on user owned hardware. The project targets a personal agent that can keep state across sessions, call language models from multiple providers, and expose its behavior through chat channels and tools without relying on a hosted service.
