Anthropic alleges DeepSeek and Chinese firms used Claude's reasoning to train AI
The AI arms race just got a lot messier. Anthropic has fired a direct accusation at DeepSeek and two other Chinese AI firms, MiniMax and Moonshot, alleging they siphoned Claude’s reasoning capabilities to build their own models. The method: “distillation,” a technique Anthropic calls legitimate in some contexts but clearly illicit here.
Over 150,000 exchanges with Claude, they claim, were used to generate “censorship-safe alternatives” to politically sensitive questions, essentially warping an American AI’s judgment into a tool for authoritarian systems. The stakes? Anthropic warns that such pilfered models, stripped of safeguards, could fuel military intelligence, cyberattacks, and mass surveillance.
DeepSeek, already notorious for shaking up the industry with its lean, powerful models, now finds itself at the center of a geopolitical firestorm.
Anthropic claims DeepSeek and two other Chinese AI companies misused its Claude AI model in an attempt to improve their own products.
The efficiency of DeepSeek’s models was never the real story. The real story is what those models were built to avoid: safeguards, oversight, accountability. Anthropic has drawn a line in the sand, naming names and detailing the mechanics of theft.
But the accusation is bigger than any single firm. It’s a warning that the unguarded frontier of AI reasoning is being mined for military-grade power, stripped of ethical constraints, and fed into systems designed to surveil, deceive, and attack. Distillation is a tool.
How it’s used determines whether we’re advancing science or enabling control. The industry can no longer pretend this is just a technical dispute. Every stolen inference is a geopolitical bet.
And the house has been called.

Common Questions Answered
What is the 'distillation' technique that OpenAI alleges DeepSeek is using?
[Reuters.com](https://uk.mobile.reuters.com/world/china/openai-accuses-deepseek-distilling-us-models-gain-advantage-bloomberg-news-2026-02-12/) describes distillation as a technique where a newer AI model learns from the outputs of an older, more established model, effectively transferring its capabilities. OpenAI claims DeepSeek is using this method to 'free-ride' on the capabilities of US AI companies by accessing their model outputs through obfuscated methods.
How did DeepSeek allegedly bypass OpenAI's access restrictions?
[InsightsWire.com](https://www.insightswire.com/news/17640/openai-alleges-deepseek-covertly-siphoned-outputs-train-r1) reports that DeepSeek employees developed methods to circumvent OpenAI's restrictions, including using third-party routers and other techniques to mask their source. OpenAI detected these 'new, obfuscated methods' designed to access their AI models and obtain outputs for training purposes.
What business and safety concerns does OpenAI raise about AI model distillation?
[VellaTimes.com](https://vellatimes.com/openai-deepseek-distillation-accusation-draws-scrutiny/) highlights that OpenAI warns when model capabilities are copied through distillation, critical safeguards can be lost or weakened. The company is particularly concerned about potential misuse in high-risk areas like biology and chemistry, and notes that the practice could erode the US advantage in AI by allowing Chinese models to compete without the significant infrastructure investments made by US companies.
