Experts doubt China's Kimi K3 used Anthropic's Fable distillation for gains

US officials, including science advisor Michael Kratsios, have accused Chinese AI company Moonshot of stealing proprietary technology by distilling Anthropic's Fable LLM to create its Kimi K3 model. However, AI experts are skeptical, arguing that the rapid advancement and capabilities of Kimi K3 are unlikely to stem solely from distillation, a process that would not allow for such quick development. These experts suggest that other advanced training methods, potentially including reinforcement learning, were likely employed, and that distillation alone is becoming less impactful for achieving frontier model performance.

    Experts say exploiting Anthropic’s Fable isn’t how Kimi K3 got so good

    "I don't think you get a model this strong and this quickly on the heels of Fable doing strictly distillation," one expert told TechCrunch.
