Analysis
This is fantastic news! Adding a code review agent to an existing AI setup significantly improved the resolution rate on the SWE-bench benchmark. The findings show that the two-agent system not only solved more problems but also offered more elegant solutions in specific cases, showcasing a powerful collaboration between AI agents.
Key Takeaways
- •A two-agent system, combining a problem-solver and a code reviewer, boosted the resolution rate from 80% to 90% on the SWE-bench benchmark.
- •The code review agent helped simplify solutions, particularly in cases involving complex documentation, demonstrating its value in preventing over-engineered fixes.
- •The researcher is open-sourcing all results, including the orchestration platform used, enabling others to reproduce and build upon the findings.
