A LocalLLaMA post claims DeepSeek now trains its models on Huawei Ascend 950 accelerators rather than NVIDIA hardware, and confirmation from DeepSeek or Huawei — or credible technical corroboration — would mark China's leading open-model lab's concrete shift off NVIDIA training silicon, while refutation marks another unverified echo.

Attention has decayed past peak (157/33, ~0 pts/h, 25th percentile); the magnitude-valve flag overstates spread since both evidence objects are the same WeChat content (gallery repost + echo reconstruction), so heat cools to low despite a hot deepseek neighborhood.

What is this?

DeepSeek is a Hangzhou-based Chinese lab widely described in the supplied coverage as China's leading open-weight model developer; its V4 family launched April 2026 and was reportedly optimized to run on Huawei's Ascend 950 processors rather than Nvidia. The specific 'now trains on Ascend 950' claim is layered and the sources partially conflict: a Huawei-led team completed full-parameter post-training (not pre-training) of the 1.6T-parameter V4-Pro on ~1,000 older Ascend 910C chips, Huawei said V4-Flash training used Ascend, and DeepSeek has ordered 160,000 Ascend 950DTs for an Inner Mongolia data center — but Bloomberg-derived reporting says that cluster is for inference and that DeepSeek still relies on Nvidia for pre-training, while a leaked, unconfirmed Liang Wenfeng transcript calls DeepSeek's ~16,000 Ascend 950 allocation insufficient to train its next frontier model. One outlet (AI in Asia) flatly claims V4-Pro was fully trained on Ascend 950 Supernode clusters, contradicting the more careful post-training-only accounts, and the training-capable 950DT reportedly only ships in Q4 2026 — so the post's claim is corroborated for post-training and serving, contradicted for full pre-training, and turns entirely on what 'trains' means.

Why it matters to Scott

Converges with the export-controls compute-chokepoint argument his wikis already carry, and the grounding's resolution sharpens it into a dated-receipts claim: Ascend substitution lands at post-training and serving (V4-Pro on ~1,000 910Cs, 160K 950DTs ordered for Inner Mongolia) while Bloomberg-derived reporting keeps full pre-training on NVIDIA — exactly the inference-vs-pre-training compute split he tracks in inference economics. As a local-inference practitioner who serves open weights on non-CUDA stacks, an Ascend-co-designed DeepSeek would also make backend portability of future weights a live question; relevance stays medium until DeepSeek or Huawei confirms and the 'trains' ambiguity resolves.
