After Anthropic Tightened Its Defenses, Chinese AI Labs Turned to OpenAI's GPT-6 Astra for Distillation
According to The Information, DeepSeek and Moonshot AI made extensive use of outputs from OpenAI's most powerful model, GPT-6 Astra, when training their latest models, involving Kimi K3.1 Pro and V4.1-Flash 1017. This kind of distillation requires models to expose hidden reasoning steps, and both OpenAI and Anthropic prohibit the practice. Claude was once the primary target, but Anthropic says the new methods have cut the amount of data attackers can obtain by 90% to 99%. In late September, OpenAI reported a coordinated distillation campaign linked to people associated with Moonshot.

Chinese AI labs are now mainly tapping OpenAI's most powerful model, GPT-6 Astra, instead of Anthropic's Claude. According to The Information , DeepSeek and Moonshot AI leaned heavily on Astra's outputs to train their latest models. People familiar with the matter say this includes Kimi K3.1 Pro and V4.1-Flash 1017.
This kind of distillation only works if the labs get the models to reveal their hidden reasoning steps. OpenAI and Anthropic both ban that. Moonshot declined to comment, and DeepSeek didn't respond to a request for comment. Claude used to be the go-to target, but Anthropic has tightened its defenses. The company says its new methods cut the amount of data attackers can pull by 90 to 99 percent .
In late September, OpenAI reported a coordinated distillation campaign that it says involved people linked to Moonshot. An OpenAI spokesperson said the company takes the problem very seriously, but until now attackers adjusted their tactics every time it rolled out a new defense.
