Good stuff. Having fp8/fp4 would be great, too!

  There are too many fp8/fp4 formats out there, many with different trade-offs. At least fp16 is standardized...

    Yes, all of them would be great.

      Hmm, you successfully nerd-sniped me. AFAIK there are at least: - 8-bit floating point types: (S1)E4M3 (finite only, has no-negative-zero variant), (S1)E5M2 (has no-negative-zero variant), E8M0 - 6-bit floating point types: (S1)E2M3, (S1)E3M2 - 4-bit floating point types: (S1)E2M1, NF4 - Block floating point types: MXFP8 (E5M2/E4M3*32+E8M0), MXFP6 (E3M2/E2M3*32+E8M0), MXFP4 (E2M1*32+E8M0), NXFP [1] [1] https://arxiv.org/pdf/2412.19821 https://arxiv.org/pdf/2412.19821 Do you have anything to add on?

        Nothing to add, I was simply saying that it would be useful to have an FP8 toy website out there covering all of these formats.
