Their are signs that China is not open sourcing their SOTA models anymore. Both Huawei and Qwen (Qwen-Max, WAN 2.5) and have launched flagship models which are yet to be opensourced.
What exactly is Huawei's flagship series anyway? Because their PanGu line is open-weight, but Huawei is as of yet not in the LLM making business, their models are only meant to signal that it's possible to do training and inference on their hardware, that's all. No one actually uses those models.
