What each one is
LangGraph
LangGraph is a library for building stateful, controllable agents as graphs, giving you fine-grained control over loops, branching and persistence.
- Explicit, controllable agent state machines
- Persistence and human-in-the-loop built in
- Integrates with the LangChain ecosystem
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
