Huawei Technologies will open-source its Compute Architecture for Neural Networks (CANN) – the software toolkit used to develop applications on the firm’s Ascend AI processors – as the Shenzhen-based company steps up efforts to compete against Nvidia, days after Beijing raised concerns about its H20 chip’s security.That move would help “speed up innovation from developers” and “make Ascend easier to use”, Huawei rotating chairman Eric Xu Zhijun said on Tuesday at the company’s developer conference in Beijing.

Huawei has already discussed with China’s leading artificial intelligence players, business partners, universities and research institutions how to build an open-source Ascend ecosystem, according to a statement from the company.
