• Says activity uses ‘distillation attacks’ to copy model behaviour; effort targets Claude’s advanced reasoning capabilities • Urges US Congress to impose penalties ARTIFICIAL intelligence company Anthropic has accused Chinese e-commerce and technology giant Alibaba of conducting a large-scale effort to extract capabilities from its Claude AI model through what it described as “distillation attacks,” according to a BBC report. In a letter sent to two US senators, Anthropic alleged that operators linked to Alibaba carried out nearly 29 million interactions with Claude using thousands of fraudulent accounts in what it called “the largest campaign to extract Claude’s capabilities illicitly”. The San Francisco-based company urged Congress to impose penalties on firms involved in such activities and strengthen safeguards against the alleged theft of US artificial intelligence technology.
