In a bold accusation, US-based AI company Anthropic has charged three Chinese AI firms - DeepSeek, Moonshot AI, and MiniMax - with industrial-scale intellectual property theft. Anthropic claims the companies used a technique called 'distillation' to rapidly enhance their AI models by extracting capabilities from Anthropic's Claude chatbot, potentially bypassing safety guardrails.

Why it matters

This case highlights the growing tensions between the US and China over AI supremacy. The alleged theft could undermine US dominance in the AI sector and raises concerns about national security implications. The controversy also shines a light on the ethics and legality of AI model distillation, a common practice in the industry.

The details

Anthropic alleges the Chinese firms achieved their ends through approximately 16 million exchanges with the Claude model and 24,000 fake accounts, allowing them to siphon off capabilities they hadn't developed independently at a fraction of the cost. The companies reportedly used proxy services to route traffic through vast networks of fraudulent accounts, circumventing Anthropic's ban on commercial access from China.

  • Anthropic discovered the alleged theft in early 2026.
