OpenAI, Anthropic, and Google Unite to Combat Unauthorized Chinese AI Model Copying

OpenAI, Anthropic, and Google have started working together to combat the unauthorized copying of their AI models by Chinese competitors. According to Bloomberg, the three companies are sharing information through the 'Frontier Model Forum,' founded in 2023, to detect so-called adversarial distillation — where outputs of an existing AI model are used to train a cheaper copycat model. US authorities estimate that adversarial distillation costs American AI labs billions of dollars in lost revenue each year. OpenAI had already warned Congress in February that DeepSeek was using increasingly sophisticated methods to extract data from US models. Anthropic identified DeepSeek, Moonshot, and Minimax as actors involved in the practice. The collaboration mirrors how the cybersecurity industry operates, where companies routinely share attack data with each other.
