Models & research

• Anthropic went public June 24 accusing Alibaba’s Qwen lab of the largest-ever distillation attack on Claude: ~25,000 fraudulent accounts ran 28.8 million exchanges between April 22 and June 5, targeting software engineering, agentic reasoning, and long-horizon task execution. Anthropic escalated to the Senate Banking Committee and the White House; the scale dwarfs the three prior cases (DeepSeek, Moonshot, MiniMax in Feb 2026) combined. Alibaba has not commented; Chinese state media called the claims unfounded. agentic-ai ai-research CNBC · Bloomberg · Nikkei Asia · Tom’s Hardware
