DeepSeek trained its new AI model on banned Nvidia Blackwell chips, is the US H200 ban backfiring?

Chinese AI lab DeepSeek trained its upcoming flagship model (slated for release any day now) on Nvidia's top Blackwell chips, which the US has fully banned from exporting to China.A senior Trump admin official confirmed the chips are likely in a data center in Inner Mongolia, and DeepSeek may scrub technical traces to hide US hardware use. Origin? Almost certainly smuggling through third countries, as seen repeatedly.

This undercuts the whole point of tight export controls, especially on the H200 (one step below Blackwell, approved for controlled sales in late 2025). Trump’s policy shifted to case-by-case licenses with strict guardrails: third-party testing, no military use, volume caps (e.g., exports ≤50% of US domestic sales), and even a 25% US fee/tariff. Yet as of late February 2026, zero H200 shipments have gone to China, stalled by ongoing US security reviews and Chinese conditions. Meanwhile, DeepSeek got even better banned Blackwells anyway. This shows: Smuggling networks remain effective for frontier hardware, even the absolute best stuff.

China's domestic alternatives (like Huawei Ascend) still lag badly, best US chips are currently \~5x more powerful than Huawei's top offerings, with the gap projected to widen to 17x by 2027 due to fab constraints (SMIC stuck at 7nm from allied controls).

But Chinese labs like DeepSeek keep closing the model gap fast through efficiency tricks and whatever compute they can access, their models already rival top US ones on cost/performance in many benchmarks, rattling markets last year and pressuring US margins.

Experts argue strict bans fuel black markets and accelerate self-reliance: China pushes harder on domestic chips and innovative architectures when cut off. Loosening H200 sales under controls could keep them dependent on Nvidia longer (earning US revenue while slowing full independence), but persistent smuggling makes the restrictions look porous. As one analysis put it, if controls truly worked, Huawei wouldn't be regressing on roadmaps, yet here we are, with top Chinese firms still advancing rapidly.
