OpenAI thwarts model-stealing campaign, but attack persists on Azure

OpenAI has reportedly thwarted a large-scale effort involving over 15,000 accounts attempting to extract the reasoning capabilities of its AI models. The company attributes some of this activity to entities linked with Moonshot AI. However, the same technique was apparently successful against Microsoft Azure for several weeks, even impacting the newer GPT-6 Astra model, indicating that OpenAI's countermeasures may not fully cover cloud platforms that distribute its models.
