What each one is
SWE-agent
SWE-agent from Princeton turns an LLM into an autonomous agent that fixes bugs in real GitHub repositories using a purpose-built agent-computer interface.
- Strong results on SWE-bench
- Purpose-built agent-computer interface
- Research-grade and reproducible
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
