It would have to be reproduced on a CUDA stack because AFAIK Huawei don't sell the Ascend 950PR (for inference) to anyone, rather, they operate them as part of the Huawei Cloud and only allow select customers (such as DeepSeek) to rent them.

The CEO of DeepSeek recently revealed to investors a lot about the resources available to DeepSeek, and the gap between Huawei and NVIDIA. Select quotes from the transcript (translation is a bit patchy on the source website though):

"We currently have roughly 20,000 H-equivalent compute cards"

"Huawei 950—right now Huawei gives us 16,000 cards, this should be publicly stateable."

"Like Huawei gives us roughly 16,000 cards of capacity, internet giants maybe get a hundred-something thousand, we get ten-something thousand—I think this ratio is also relatively... but this is probably just how much capacity Huawei has."

"16,000 Huawei 950 cards only equal 4,000 B-series cards."

"Huawei’s supernode, Huawei’s 950 supernode, in performance and price can completely substitute for NVIDIA’s GB200, GB300. The price is definitely more expensive, but limitedly so. Fifty percent more expensive, a hundred percent more expensive—a hundred percent more doesn’t matter, two hundred percent more doesn’t matter. For example, a hundred percent more expensive—I think it can already be considered a price-level substitute."

"I think domestic hardware might need a few years."

"I don’t quite believe that five years from now, we’ll still be stuck on the production capacity problem. Right now we’re definitely stuck on the production capacity problem—this year, next year, the year after, I think we might still be stuck on the production capacity problem, but five years later, I think maybe not necessarily—I’m still relatively optimistic."
