OpenAI, Anthropic, and Google have formed an alliance to combat adversarial model distillation, particularly targeting Chinese AI firms. This collaboration, reported by Bloomberg, involves sharing information through a 'cutting-edge models forum' to identify and counteract distillation activities. The move follows Anthropic's report accusing companies like DeepSeek and MiniMax of creating fraudulent accounts to extract data from their models for training purposes. The practice of model distillation, which involves replicating the capabilities of advanced models at a lower cost, has become a contentious issue. While technically legitimate, adversarial distillation—using services to develop competing models—is often prohibited by companies like OpenAI and Anthropic. The alliance aims to protect their investments and address potential risks associated with illegally distilled models, which may bypass safety measures.
