In the Xiaomi MiMo vs DeepSeek battle, the most interesting AI lab in the world right now might be a phone company.
Xiaomi, best known for smartphones and electric cars, just released MiMo-V2.6-Pro, which debuted as the highest-scoring open-weight AI model in the world on Artificial Analysis’ Intelligence Index with a score of 46. That puts it ahead of DeepSeek’s best open model at 36, ahead of xAI’s Grok 4.6, and within touching distance of closed frontier models from Anthropic and OpenAI.
The model carries an MIT license. As a result, anyone can download it from Hugging Face, fine-tune it, and run it on their own hardware without paying Xiaomi anything.
Xiaomi MiMo vs DeepSeek: the cost story is the real story
Here is the number that should make every founder sit up: Xiaomi says it trained the flagship model for roughly $2.62 million, completing its reinforcement learning run in under six days. In addition, the smaller Flash variant cost about $850,000.
Not long ago, people discussed frontier AI training runs in terms of hundreds of millions of dollars. In contrast, Xiaomi did it for the price of a nice house in San Francisco. Fuli Luo, a former DeepSeek researcher, led the team, which tells you something about where the talent is flowing.
Moreover, API pricing is equally aggressive: $0.435 per million input tokens and $0.87 per million output tokens. Artificial Analysis measures the cost per task at roughly one-twentieth to one-sixtieth of leading international models.
What this means for your business
First, if you are building a company on top of AI APIs, your cost structure just got a preview of its future. Open-weight models at near-frontier quality, available for free, runnable on rented hardware. Labs releasing their work to the world are competing away the margin that proprietary API providers used to enjoy.
The strategic move for founders: build your product so the model underneath is swappable. The winners of the next phase will not be the companies with the best model. They will be the companies with the best product on top of commodity intelligence.
DeepSeek proved open models could compete. Finally, Xiaomi just proved they can win. Your AI bill is about to get a lot smaller, and your moat needs to be somewhere else.
