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.

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 has denied claims that its Pangu Pro MoE model copied Alibaba’s Qwen 2.5 14B, after an anonymous paper alleged high similarity between the two.
