Cute trick but it's not exactly a secret, e.g. deepseek recently published their own inference engine -- and it only has kernels for SM100 (blackwell) and Huawei Ascend 950, and all its published performance results using blackwell.

And these were completely openly disclosed as headline properties of the software: https://github.com/deepseek-ai/DeepInfer/tree/main/#performa...

No one found it remarkable a couple weeks ago, ... but now the fact that DS is using blackwell is apparently some super secret requiring clever RNG init stats???
