Anthropic Distillation Accusations: Largest Model Theft Claim in AI History

Anthropic formally accused DeepSeek, Moonshot AI, and MiniMax of using 24K fake accounts and 16M exchanges to extract Claude's capabilities. The targeting specifically hit agentic reasoning, tool use, and coding — the exact capabilities powering the tools builders use daily. MiniMax reportedly pivoted to new Claude models within 24 hours of release. For builders, this raises dependency questions: if your agent stack depends on models that may themselves be distilled copies, what's your actual supply chain?
