Cursor's "Shelling" Kimi Controversy Reverses: From Infringement Allegations to Authorized Cooperation, China's Open-Source Models Once Again Become the Global AI Foundation

On March 20, AI programming tool Cursor (parent company Anysphere, valued at $29.3 billion) released its self-developed model Composer 2, claiming performance improvements through continued pre-training and reinforcement learning, without disclosing the base model source. Shortly after, a captured API request revealed the model ID as "kimi-k2p5-rl-0317-s515-fast," suggesting it was built on Kimi K2.5. Moonshot AI’s pre-training lead Du Yulun initially accused Cursor of violating Kimi’s modified MIT license, which requires commercial products exceeding certain revenue or user thresholds to credit Kimi model usage. The controversy gained traction with Elon Musk’s public comment. However, the situation reversed when Moonshot AI officially congratulated Cursor, clarifying that the usage was authorized through Fireworks AI’s commercial platform. Cursor’s co-founder Aman Sanger and VP Lee Robinson later explained that Kimi K2.5 was selected as the strongest base model after evaluation, and Composer 2 involved significant additional training by Cursor. They admitted failure to credit Kimi initially was a mistake. This incident highlights the growing influence of Chinese open-source models in the global AI ecosystem, as noted by Hugging Face’s CEO. It also serves as indirect validation for Moonshot AI, which is currently raising funds at a $18 billion valuation, suggesting its technology may be even more valuable than estimated.
