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
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
