It was natively trained in FP4. Probably both to reduce VRAM usage at inference time (fits on a single H100), and to allow better utilization of B200s (which are especially fast for FP4).

Interesting, thanks. I didn't know you could even train at FP4 on H100s
It's impressive they got it to work — the lowest I'd heard of this far was native FP8 training.
