- supportsWill DePue: DePue's November 12 report describes roughly six trillion tested seed/layout combinations and physical B300/GB200 reproduction as checks against coincidental initialization matches; it does not establish hardware location or a procurement violation.
Our investigation, search-space multiple-testing caution; Verifying the findings and Limits of the investigation
- supportsWill DePue: DePue reports reproducing 445 entire DeepSeek-V4-Flash rows bit for bit on NVIDIA B300 and 13 Kimi K3 rows on GB200; a specially configured AMD MI300X can mimic the SM layouts, but the V4-Flash numerical discriminator favors NVIDIA in 363 of 377 divergent values, with no AMD matches.
Verifying our findings: B300 461/469 rows (445 exact) and GB200 13 rows; Limits of our investigation: AMD MI300X test and 363/377 discriminator
