Anthropic alleges Alibaba led the largest Claude-cloning effort

TL;DR
Anthropic claims Alibaba conducted the largest illicit distillation campaign to clone Claude, using about 25,000 fraudulent accounts to generate 28.8 million exchanges with Claude from April 22 to June 5 and evading detection with proxies; the firm argues such attacks threaten US AI leadership and urges Congress to update antitrust information-sharing, impose export controls on chips, and penalize Chinese labs to deter future distillation attempts.
