People familiar with the matter say this includes [Kimi K3.1 Pro](https://the-decoder.com/chinese-ai-model-kimi-k3-1-pro-is-closing-in-on-anthropics-claude-opus-5-5/) and V4.1-Flash 1017.\n\nThis 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](https://the-decoder.com/anthropic-says-it-cut-claude-reasoning-token-theft-by-up-to-99-in-fight-against-industrial-scale-distillation/).\n\nIn late September, OpenAI reported a [coordinated distillation campaign](https://the-decoder.com/openai-says-it-stopped-a-campaign-to-steal-its-models-reasoning-but-the-trick-still-worked-on-azure/) 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.\n\n```\nAI News Without the Hype – Curated by Humans\n\n\t\t\t\t\tSubscribe to THE DECODER for ad-free reading, a weekly AI newsletter, our exclusive \"AI Radar\" frontier report six times a year, full archive access, and access to our comment section.\t\t\t\t\n\n\t\t\t\t\tSubscribe now\n```\n\n[The Information](https://www.theinformation.com/articles/openais-astra-model-becomes-top-distillation-target-chinas-ai-labs)", "url": "https://wpnews.pro/news/openai-s-astra-becomes-the-main-target-for-chinese-ai-labs-after-anthropic-its", "canonical_source": "https://the-decoder.com/openais-astra-becomes-the-main-target-for-chinese-ai-labs-after-anthropic-tightens-its-defenses/", "published_at": "2026-10-29 13:20:14+00:00", "updated_at": "2026-10-29 13:47:11.296432+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "ai-safety", "ai-policy"], "entities": ["OpenAI", "Anthropic", "DeepSeek", "Moonshot AI", "GPT-6 Astra", "Claude", "Kimi K3.1 Pro", "The Information"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/openai-s-astra-becomes-the-main-target-for-chinese-ai-labs-after-anthropic-its", "markdown": "https://wpnews.pro/news/openai-s-astra-becomes-the-main-target-for-chinese-ai-labs-after-anthropic-its.md", "text": "https://wpnews.pro/news/openai-s-astra-becomes-the-main-target-for-chinese-ai-labs-after-anthropic-its.txt", "jsonld": "https://wpnews.pro/news/openai-s-astra-becomes-the-main-target-for-chinese-ai-labs-after-anthropic-its.jsonld"}}
