BluTrain is a C++/CUDA framework built on the thesis that at scale, deep-learning progress comes more from throughput and training behavior than from model architecture. Same instinct as Dwarkesh's data argument, pointed at the metal instead of the data. For teams squeezing efficiency out of GPU clusters or building custom training infra, it's worth a read.
