China's Kimi K3 Model Sparks US Accusations and Industry Divide

The release of Chinese AI lab Moonshot AI's Kimi K3 model has ignited a fierce debate over intellectual property theft and the future of open-source AI. The White House has accused Moonshot of illegally distilling Anthropic's Fable 5 model to build Kimi K3, a charge the company denies. Distillation, a common technique where a smaller model learns from a larger one, is at the center of the dispute.
