Xiaomi Releases and Open-Sources MiMo-V2.6 Series Large Models, Keeps V2.5 API Pricing
On September 22, Xiaomi released and open-sourced its Xiaomi MiMo-V2.6 series of large models, described as a key step in exploring recursive self-improvement (RSI) by scaling reinforcement learning (RL) compute on verifiable complex tasks. The series includes two native full-modal models: MiMo-V2.6-Pro and MiMo-V2.6-Flash. According to Xiaomi, MiMo-V2.6-Pro scored 46 on the Artificial Analysis Intelligence Index, surpassing Kimi K3 and Qwen3.8 Max to become the strongest open-source model, though still behind closed-source leaders Claude Fable 5.1 and GPT-6 Astra. API pricing remains unchanged from the V2.5 series. On September 17, MiMo team lead Luo Fuli shared real-time training pages on X, revealing that MiMo-V2.6-Pro training cost $890,000 over 1 day 19 hours (over $20,000/hour), and MiMo-V2.6-Flash cost $397,000 over 1 day 14 hours (over $10,000/hour), totaling about $31,000 per hour. Xiaomi expanded RL compute across three dimensions, supporting 1M context length training with 2.7–3.7B tokens per step, and built a multi-task training system covering Code, General, Visual, and Cyber directions. Xiaomi has open-sourced the technical report, training environment, and RL code.

On September 22, Xiaomi officially released and open-sourced its new Xiaomi MiMo-V2.6 series of AI models, including Pro and Flash variants. The company claims that due to expanded reinforcement learning compute, the MiMo-V2.6-Pro model scored 46 on the Artificial Analysis Intelligence Index (AA Comprehensive Intelligence Index), surpassing Kimi K3 and Qwen3.8 Max to become the strongest open-source model currently available. However, it still trails behind leading closed-source models such as Claude Fable5.1 and GPT-6 Astra. Xiaomi stated that the MiMo-V2.6 series maintains the same API pricing as the V2.5 series, and that MiMo-V2.6-Pro sets a new cost-performance record for domestic models, with prices ranging from 1/20 to 1/60 of comparable overseas models at the same intelligence level.

On September 22, Jin10 Data reported that Xiaomi officially released and open-sourced the new Xiaomi MiMo-V2.6 series early this morning. The team stated that the MiMo-V2.6 series includes two native full-modal models: Pro and Flash. Thanks to expanded RL computing power, MiMo-V2.6-Pro scored 46 points on the Artificial Analysis Intelligence Index (AA Comprehensive Intelligence Index), surpassing Kimi K3 and Qwen3.8 Max to become the current strongest open-source model. However, it still lags behind the strongest closed-source models, Claude Fable5.1 and GPT-6 Astra. The team noted that the MiMo-V2.6 series maintains the same API pricing as the V2.5 series, with MiMo-V2.6-Pro setting a new cost-performance record for domestic models: at the same intelligence level, its price is only 1/20 to 1/60 of overseas models.
