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

Key Points:

• White House science advisor Michael Kratsios accused Chinese company Moonshot of copying Anthropic’s Fable large language model (LLM) and using advanced Nvidia chips banned from export to China, raising concerns about industrial espionage and technology theft.
• Experts express skepticism that Moonshot’s Kimi K3 model was solely developed through distillation—a process of querying and fine-tuning existing models—citing the short timeframe since Fable’s release and the complexity of achieving such advanced capabilities.
• Distillation and supervised fine-tuning remain common practices in AI development globally, including in the U.S., but more advanced reinforcement learning techniques and significant infrastructure are typically required to replicate frontier models’ performance.
• Anthropic previously accused Moonshot and other Chinese firms of systematically extracting capabilities from its models, while experts highlight the technical expertise of Chinese AI teams and note that progress in China’s AI sector is not solely dependent on copying U.S. models.
• The use of banned Nvidia chips by Moonshot points to a black market for advanced hardware, with calls from experts for stricter oversight and reporting mechanisms for data centers worldwide to prevent illicit technology transfers.
