Kimi K3 trained on 20,000 Nvidia chips accessed through Alibaba's cloud

Moonshot trained its Kimi K3 model on a cluster of 20,000 Nvidia chips accessed through Alibaba's cloud, according to a Bloomberg report covered by The Next Web on 31 July 2026. The chips are reported to form a substantial portion of Moonshot's total compute capacity. The disclosure lands in the middle of an already contentious argument over how Chinese laboratories obtain the hardware, and allegedly the distilled capability, needed to build frontier models.

What the report says

Multiple sources told Bloomberg the arrangement is specifically for H200 processors, Nvidia's most powerful Hopper-generation accelerators. Alibaba denied providing H200s. It did not deny the 20,000-chip arrangement itself, and it declined to say which chips are involved.

The physical location of the cluster is unclear. That detail matters because Chinese cloud companies have sometimes accessed restricted chips owned by foreign firms in overseas locations and re-leased that capacity domestically, a pattern that has complicated enforcement of US export controls.

An awkward outcome for Alibaba

Alibaba is one of Moonshot's largest investors and, per the reporting, expects the companies it backs to use its cloud. The awkwardness is that Kimi K3, trained on Alibaba's infrastructure, now outperforms Alibaba's own Qwen models on key benchmarks. Bloomberg reported that some people inside Alibaba are disappointed that a rival team with access to similar resources produced the stronger model.

Kimi K3 launched as the world's largest open-weight model at 2.8 trillion parameters, and by the reporting it matches Anthropic's Fable 5 and OpenAI's GPT-5.6 on several metrics.

The separate Blackwell question

The Alibaba arrangement is distinct from a second, more politically charged claim. White House official Michael Kratsios has accused Moonshot of illegally acquiring Nvidia's most advanced Blackwell chips. A person familiar with Moonshot confirmed that the company has a channel for accessing Blackwell processors via Southeast Asia, without specifying whether it involves rental, which is generally legal, or direct purchase, which would breach US regulations. Moonshot is reportedly seeking additional Blackwells for its next model.

Distillation allegations remain unproven

Kratsios also claimed that Moonshot used distillation against Anthropic's Fable model to train K3. Per The Next Web's account, he provided no evidence for that claim. It sits alongside Anthropic's own accusation that Alibaba's Qwen laboratory ran the largest distillation campaign ever conducted against Claude, using 25,000 fake accounts. Both remain allegations, and the reporting reviewed here contains no independent verification of either.

The broader framing offered by The Next Web, that Hopper chips from cloud agreements, Blackwell access via Southeast Asian intermediaries and alleged distillation together show the export controls have not worked as intended, is an assessment drawn from these events. It is not an official finding.

What is established and what is merely claimed

Established:

• Bloomberg reported, and The Next Web covered on 31 July 2026, that Moonshot trained Kimi K3 on a 20,000-chip Nvidia cluster supplied through Alibaba's cloud, forming a substantial portion of Moonshot's compute capacity.
• Alibaba denied supplying H200 chips, did not deny the 20,000-chip arrangement, and declined to identify the chips involved.
• Alibaba is one of Moonshot's largest investors.
• Kimi K3 is a 2.8 trillion parameter open-weight model that outperforms Alibaba's Qwen models on key benchmarks.
• A person familiar with Moonshot confirmed a channel for accessing Blackwell processors via Southeast Asia, while leaving open whether it involves rental or purchase.

Merely claimed:

• That the 20,000 chips are H200s, which comes from unnamed sources and which Alibaba disputes.
• That Moonshot illegally acquired Blackwell chips, an accusation by Michael Kratsios that the confirmed Southeast Asian channel does not by itself settle, since rental is generally legal and only direct purchase would breach US rules.
• That Moonshot distilled Anthropic's Fable model to train K3, a claim Kratsios made without providing evidence.
• That Alibaba's Qwen laboratory ran a distillation campaign against Claude using 25,000 fake accounts, an accusation by Anthropic that remains unverified.
