Microsoft and OpenAI are investigating whether data output from OpenAI’s technology was obtained in an unauthorised manner by a group linked to Chinese artificial intelligence start-up DeepSeek, according to people familiar with the matter.
Microsoft’s security researchers last year observed individuals they believe may be linked to DeepSeek exfiltrating a large amount of data using the OpenAI application programming interface, or API, said the people, who asked not to be identified because the matter is confidential.
