In mid-2026, FP8 and FP4 have become essential tools for making large-scale AI training and inference more efficient . FP8 uses two main formats-E4M3 for better precision on activations and weights, and E5M2 for wider dynamic range on gradientswhile NVIDIA’s NVFP4 takes things further with 4-bit...
