DeepSeek Blocks Release of New V4 Model, Denies US Chipmakers Including Nvidia Access

DeepSeek’s decision to keep its V4 model under wraps from U.S. chipmakers comes amid a broader supply‑chain squeeze that has already delayed the model’s launch. Reuters reported that the Chinese AI firm’s rollout was postponed after Huawei, a key hardware partner, ran into chip‑availability problems, a setback that the Financial Times had earlier flagged (Reuters). By refusing to share the V4 code with Nvidia and other U.S. manufacturers, DeepSeek effectively removes the most powerful testing platform from the ecosystem that powers much of the world’s AI inference workloads. Business‑Standard noted that the move “effectively halting the hardware partner’s ability to test the new system,” underscoring how the firm is leveraging its own silicon strategy to retain control over the model’s performance metrics (Business‑Standard).

The timing of the block is notable because DeepSeek has been positioning V4 as a direct challenger to the next generation of large language models from OpenAI and Google. VentureBeat highlighted the company’s recent release of two “insanely powerful” models that it claims rival GPT‑5, and emphasized that those models are offered free of charge (VentureBeat). By restricting access to V4, DeepSeek appears to be drawing a line between its publicly available, lower‑tier offerings and a premium tier that it intends to keep exclusive to partners that can meet its hardware requirements—chief among them, domestic Chinese chipmakers. This strategy mirrors a pattern seen in other Chinese AI firms that have increasingly insulated their most advanced models from Western tooling, citing security and intellectual‑property concerns.

Industry observers see the move as a test of China’s ambition to build a self‑sufficient AI stack. The Reuters piece on Alibaba’s launch of the Qwen 3.5 model, described as ushering in an “agentic AI era,” illustrates how Chinese players are rapidly iterating on large‑scale models while simultaneously developing in‑house accelerators (Reuters). DeepSeek’s refusal to grant Nvidia access to V4 could therefore be interpreted as a defensive posture: protecting a competitive edge while the domestic chip ecosystem catches up. The same Reuters report that covered the Huawei delay also noted that DeepSeek’s partnership with the Chinese telecom giant has been critical for scaling its training infrastructure, suggesting that the firm’s hardware roadmap is now tightly coupled with home‑grown silicon rather than the globally dominant Nvidia GPUs.

The fallout for U.S. chipmakers could be significant if DeepSeek’s V4 proves to be a benchmark‑setting model. Nvidia, which supplies the majority of AI inference hardware worldwide, relies on early access to new models to optimize drivers and firmware. By cutting off that pipeline, DeepSeek not only delays Nvidia’s ability to certify performance but also risks creating a parallel ecosystem where Chinese AI workloads run on alternative architectures. Analysts, however, caution that the impact may be limited in the short term. The Business‑Standard article did not cite any immediate revenue loss for Nvidia, and the broader market has already begun to accommodate a diversification of AI hardware providers, as seen in the rise of AMD, Graphcore, and emerging Chinese ASICs. Nonetheless, the episode underscores a growing geopolitical dimension to AI development, where access to cutting‑edge models becomes a lever of strategic advantage.
