OpenAI alleges evidence China's DeepSeek used its model for training

SAN FRANCISCO/BEIJING (Financial Times) -- OpenAI says it has found evidence that Chinese artificial intelligence startup DeepSeek used the U.S. company's proprietary models to train its own open-source competitor, as concerns grow over a potential breach of intellectual property.

The San Francisco-based ChatGPT maker told the Financial Times it had seen some evidence of "distillation," which it suspects to be from DeepSeek.
