Xiaomi’s open-weight MiMo-V2.5-Pro takes aim at Claude Opus with hours-long autonomous coding

Xiaomi’s new MiMo-V2.5-Pro nearly matches Anthropic’s Claude Opus 4.6 on coding benchmarks while burning 40 to 60 percent fewer tokens, according to the company. The release pushes Xiaomi deeper into the race among Chinese open-weight providers like Deepseek, where the fight is shifting from raw benchmark scores to how cheaply and how long a model can run autonomously on a single task.
