中国AI实验室转向OpenAI的GPT-6 Astra模型，Anthropic加强防御
OpenAI's Astra becomes the main target for Chinese AI labs after Anthropic tightens its defenses
中国AI实验室主要使用OpenAI的GPT-6 Astra模型，而非Anthropic的Claude。Anthropic加强了对Claude的防御，减少了攻击者可获取的数据量。
中国AI实验室转向使用OpenAI的GPT-6 Astra模型，反映了AI领域的技术竞争和策略调整。
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.
