报道称中国 AI 实验室蒸馏目标转向 OpenAI GPT-6 Astra
原标题：OpenAI's Astra becomes the main target for Chinese AI labs after Anthropic tightens its defenses
据 The Information 报道，DeepSeek 和 Moonshot AI 在训练最新模型 Kimi K3.1 Pro 和 V4.1-Flash 1017 时大量依赖 OpenAI GPT-6 Astra 的输出。此前 Claude 是主要蒸馏目标，但 Anthropic 称新防御方法将攻击者可提取的数据量减少了 90% 到 99%。OpenAI 9 月下旬曾报告一次协调性蒸馏行动，称涉及与 Moonshot 有关的人员；Moonshot 拒绝置评，DeepSeek 未回应。
为什么值得看原文梳理了中国实验室蒸馏目标从 Claude 转向 GPT-6 Astra 的原因，以及 OpenAI 和 Anthropic 各自的防御进展。

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.
