Xiaomi has officially launched and open-sourced the Xiaomi MiMo-V2.6 series, which includes two native full-modal versions: Pro and Flash. These models underwent approximately six days of large-scale live reinforcement learning training, optimized using 750,000 trajectory data points. Tests indicate that the Pro model achieved a score of 46 on the AA Comprehensive Intelligence Index, outperforming Kimi K3 and Qwen3.8 Max, thereby establishing its status as the current strongest open-source model. Despite this strong performance, a technical gap remains when compared to top closed-source models such as Claude Fable 5.1 and GPT-6 Astra.
