OpenAI claims Moonshot extracted its data to train AI models.

OpenAI says it disrupted what it describes as a coordinated campaign meant to extract “protected reasoning” from its AI models through a technique it calls model distillation. The company has not tied the activity to a single individual, but says it traced a “core cluster” of the effort to Moonshot, the Chinese firm behind the Kimi model. The allegations build on similar claims: Anthropic has also accused Moonshot of comparable behavior. OpenAI published a detailed post describing the disruption and linking the activity to the Moonshot cluster, framing it as an attempt to obtain protected internal reasoning rather than simply use models normally.
