fp8

FP8 is the format behind modern H100-class training and serving. The signal is knowing the two FP8 variants, why a floating format beats INT8 for dynamic range, and where scaling still matters.

Beyond FP16/BF16, FP8 is the next rung on the precision ladder, and the latest tensor cores compute on it natively. The signal is knowing the two formats, what FP8 actually buys, and why dynamic range forces careful scaling.

FP8 serving is fast and usually fine, until it silently degrades on the one workload your benchmark did not cover. The signal is knowing what FP8 breaks and how to validate it. Here is the recipe.

FP8 promises to roughly double training throughput over BF16, but with only a handful of mantissa bits the numerics are unforgiving. Per-tensor scaling and a selective recipe are what make it converge.
