Chinese firms systematically misuse Anthropic's Claude AI model
Anthropic reported that Chinese AI companies, including DeepSeek, systematically misused its Claude model through approximately 24,000 fake accounts to conduct over 16 million interactions. The firms used a distillation technique to extract Claude's outputs for training competing AI models.
What happened
Anthropic announced on February 23, 2026 that Chinese AI development companies had systematically misused its Claude model. The firms, including DeepSeek and two other Chinese AI research laboratories, used approximately 24,000 fake accounts to conduct over 16 million interactions with Claude.
The Chinese companies employed a technique called "distillation," using high-performance AI model outputs to train other models. Anthropic warned that such activities were increasing in intensity and sophistication.
Reported impact
Distillation techniques used by competitors could allow them to rapidly and inexpensively mimic advanced AI capabilities. Anthropic called for prompt action from policymakers and AI industry stakeholders.
