Australia Treasurer Jim Chalmers on Wednesday urged Australians to be cautious when using Chinese AI model DeepSeek, the latest government to warn over its use.

OpenAI says it has found evidence that Chinese artificial intelligence start-up DeepSeek used the US company’s proprietary models to train its own open-source competitor, as concerns grow over a potential breach of intellectual property.

As Chinese AI company DeepSeek gains traction in the tech world amid ongoing US-China trade tensions, OpenAI suspects that DeepSeek may have utilized ChatGPT data to develop its own cost-effective AI models.
