Xiaomi’s MiMo Code claims it beats Claude Code past 200 steps
TL;DR
Coding agents often struggle with long tasks, typically failing around 30 steps due to compounding errors. Xiaomi has developed MiMo Code, an open-sourced tool that reportedly outperforms Anthropic's Claude Code in tasks exceeding 200 steps.
✦ Why It Matters
Engineers can leverage MiMo Code to improve the reliability of coding agents in complex software projects.
Key Takeaways
- Assess coding agents on their ability to maintain coherence over long tasks.
- Consider independent benchmarks like Agents' Last Exam for reliable evaluations.
- Investigate how well a candidate harness manages state across extended runs.
- Be cautious of self-reported performance claims without third-party validation.
How It Works
MiMo Code utilizes a terminal-native harness that focuses on maintaining task coherence over long sequences of coding steps. It aims to prevent common pitfalls such as hypothesis lock-in and error compounding by allowing for better state management and checkpointing.
