Six Chinese AI firms accused of aggressively copying US frontier models
NSA, CISA, and FBI accuse DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun, and Z.AI of industrial-scale distillation of US frontier models via API abuse.
A joint NSA, CISA, and FBI release alleges six Chinese AI firms have extracted capabilities from US frontier models, including Claude, GPT, Gemini, and Grok, since at least late 2024, likely with Chinese government awareness. Tactics include bulk procurement of premium subscriptions with fraudulent accounts, proxy routing to evade geo-restrictions, and prompt injection to force models to reveal hidden chain-of-thought reasoning. Agencies recommend stronger identity verification, monitoring of anomalous usage, and quietly downgrading or adding noise to responses for suspected distillers, while warning these mitigations could frustrate legitimate users.
- Six firms named: DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun, and Z.AI.
- Methods: bulk fake accounts, shared premium subscriptions, and prompts extracting chain-of-thought reasoning.
- Mitigations urged: identity verification, anomalous-usage detection, silent downgrade of suspected accounts.
- Agencies say distillation shortens Chinese development timelines and cuts frontier training costs.
