Xiaomi Stock Jumps 5.8% After Covert AI Launch
Xiaomi's stock gained 5.8% on March 18 after the company executed what its AI chief called a "quiet ambush" in the competitive artificial intelligence market. The surge followed the revelation that a high-performing anonymous model, 'Hunter Alpha,' which appeared on the OpenRouter platform on March 11, was an internal test build of Xiaomi’s new MiMo-V2-Pro. The model rapidly climbed leaderboards and sparked widespread speculation that it was the unreleased DeepSeek V4, driving over one trillion tokens in usage before its true identity was confirmed.
The reveal by Luo Fuli, head of Xiaomi's MiMo division, repositions the $137 billion technology giant as a formidable AI contender. While primarily known for smartphones, Xiaomi’s portfolio includes electric vehicles, consumer electronics, and a recent partnership with the Sei blockchain. This strategic launch validates its deep technological capabilities beyond hardware manufacturing and places it in direct competition with established AI leaders like Google, OpenAI, and other major Chinese firms.
MiMo-V2-Pro Undercuts Rivals By Up To 80% on Price
Xiaomi is leveraging a disruptive pricing model to capture market share. MiMo-V2-Pro costs just $1 per million input tokens and $3 per million output tokens. This is significantly cheaper than competing models like Anthropic's Claude Sonnet 4.6 ($3 input / $15 output) and Claude Opus 4.6 ($5 input / $25 output), representing a cost reduction of up to 80% for developers on output-heavy tasks. This pricing makes building scalable, agentic AI systems more economically viable, directly targeting a key growth area in the industry.
Despite the low cost, MiMo-V2-Pro’s performance is competitive with top-tier models. On the SWE-bench for software engineering tasks, it scored 78%, nearing Claude Opus 4.6's 80.8%. It also ranks eighth worldwide on the Artificial Analysis Intelligence Index. The trillion-parameter model, which uses a Mixture-of-Experts (MoE) architecture with 42 billion active parameters per request, demonstrated strong capabilities in coding and creative writing during hands-on testing, though it showed limitations in solving complex mathematical problems.
Chinese Models Lead Global AI Usage, Up 57% Week-Over-Week
Xiaomi's successful launch occurs within a broader market shift where Chinese AI models are outpacing their U.S. counterparts in global usage. According to data from OpenRouter, Chinese models have led in usage for three consecutive weeks. Last week, five of the top nine models were Chinese, with MiMo-V2-Pro leading the pack. Total token usage for these models expanded 57% to 7.359 trillion tokens from the previous week.
This growth starkly contrasts with the usage of top U.S. models from Google and Anthropic, which collectively grew by a modest 7.3% to 3.536 trillion tokens over the same period. The trend highlights an accelerating adoption of Chinese AI, fueled by open-source availability and aggressive pricing. This pattern was further underscored when a U.S. AI firm, Cursor, acknowledged basing its latest product on Kimi 2.5, another model from a Chinese startup, demonstrating the increasing influence and integration of Chinese AI technology in the global developer ecosystem.
