What each one is
Hermes Agent
Hermes Agent from Nous Research is an autonomous agent built to accumulate context over time rather than start from zero at each session, so its usefulness compounds with use.
- Carries context forward between sessions
- MIT licence with no usage restriction
- Backed by a research lab with a track record on open weights
OpenAI Swarm
Swarm is a deliberately tiny framework showing how agents can hand off work to one another, built for learning rather than production.
- Extremely small and readable
- Clear handoff and routine patterns
- Great teaching material
