MiMo Code: The Coding Agent Built for Marathon Tasks

Most coding agents collapse when tasks exceed 50 steps—context fills up, reasoning breaks down, and errors cascade unchecked. MiMo Code inverts this design problem by treating long-horizon reliability as a core architectural concern, using strategic checkpoints, parallel verification, and persistent memory to maintain coherence across 200+ step tasks. This approach could fundamentally reshape how autonomous coding systems should be designed, shifting focus from raw benchmark performance to practical robustness at scale.
