Live-SWE-agent: live, self-evolving software agent

📣News | 📊Comparison | 🚀Setup | ⚙️Artifacts | 📜Attribution | 🙏Acknowledgements

Live-SWE-agent is the first live, runtime self-evolving software engineering agent that expands and revises its own capabilities on the fly while working on a real-world issue. Our key insight is that software agents are themselves software systems, and modern LLM-based agents already possess the intrinsic capability to extend or modify their own behavior at runtime.

📣 News

• [Nov 17th, 2025]: Live-SWE-agent achieves the new state-of-the-art solve rate of 45.8% on SWE-Bench Pro!
• [Nov 17th, 2025]: We've released Live-SWE-agent 1.0.0!

📊 Comparison

Below shows the comparison graph between Live-SWE-agent and state-of-the-art open-source solutions and proprietary commercial agent scaffolds on SWE-bench Verified and SWE-Bench Pro.

🚀 Setup

We built Live-SWE-agent on top of the popular mini-swe-agent framework with very minimal modifications.

To use Live-SWE-agent, simply install mini-swe-agent first using this guide and use the custom Live-SWE-agent config:

mini --config config/livesweagent.yaml # using custom Live-SWE-agent config

See the config folder for more details.
