Huawei Technologies Co.’s secretive AI research lab has pushed back against accusations it relied on rivals’ models to develop its own Pangu platform, taking the unusual step of rebutting claims about its artificial intelligence efforts.

Huawei's artificial intelligence research division has rejected claims that a version of its Pangu Pro large language model has copied elements from an Alibaba model, saying that it was independently developed and trained.

A public feud over model originality threatens China’s collaborative AI front, with Huawei denying whistleblower claims of cloning Alibaba’s Qwen model amid rising global scrutiny.
