OpenAI, Anthropic, and Google are collaborating to prevent competitors from copying their artificial intelligence models. This rare alliance specifically targets entities in China attempting to replicate advanced AI systems.

The companies aim to stop adversarial distillation, where third parties use AI outputs to train rival models. This practice violates terms of service and follows previous industrial-scale distillation attacks the labs identified and blocked.

The Frontier Model Forum facilitates this information sharing. Microsoft co-founded the industry group with the three labs in 2023 to address growing intellectual property threats.
