## Researcher Claims Six Chinese AI Models Use Banned Nvidia Chips
Will DePue published a report on 12 November saying six models from DeepSeek, Moonshot, MiniMax and Ant Group were initialised on Nvidia's Blackwell chips.

> conclusive forensic evidence
## Method Detects Hardware Fingerprint in AI Models
DePue says starting weights show hardware patterns that survive training, matching 24 models where developers disclosed their hardware.

> the starting values of its weights are generated in a pattern that depends on the exact gpu and the random seed
## Evidence Strength Ranges from 49 to 1,385 Standard Deviations
The evidence for six models ranges from 49 to 1,385 standard deviations above chance, with the weakest test reaching 20.

> 20. standard deviations
## Blackwell B300 Reproduces Starting Weights Bit for Bit
A Blackwell B300 reproduced DeepSeek-V4-Flash's starting weights using the recovered seed, while an older H100 did not.

## Report Does Not Name Singapore or Megaspeed
The report does not name Singapore or Megaspeed, and these are separate from the six models.

## Estimated Cost of Blackwell GPUs for Models
DePue estimates the largest clusters used 2,000 to 3,000 Blackwell GPUs each at $150 million to $200 million per cluster.

> two thousand to three thousand blackwell gpus
## Washington Tightens AI Chip Export Rules
The Commerce Department clarifies that advanced AI chip export licenses apply to China-headquartered companies even when overseas subsidiaries are the buyers.

## Who Has Checked the Findings
DePue claims independent verification by OpenAI and Anthropic researchers, but no labs or Nvidia have responded.

> independently verified by senior researchers at openai and anthropic
## Questions Raised by the Findings
Where were the chips? Does the scale fit? What did Nvidia know? Can the rules catch this? Who is checking?

> the questions this raises
## California CEO Charged in Chip Smuggling Scheme
Federal prosecutors charged Greg Lui with smuggling more than $300 million in Nvidia-powered servers to China via Malaysia and Singapore.

> more than three hundred million
## What Happens Next
The labs, Nvidia or independent researchers must respond to the findings before the story settles.

> the labs, nvidia or outside researchers respond
## Key takeaway

Researcher claims six Chinese AI models were trained on banned Nvidia Blackwell chips, sparking legal and export control concerns.
