nx_nofloat_mxfp8.nx -- SOVEREIGN no-float MXFP8 dequant (K3 F406; operator 2026-07-19 "state of the art"). Completes the OCP Microscaling (MX v1.0) story begun in nx_nofloat_mxfp4: Kimi K3 uses MXFP4 WEIGHTS + MXFP8 ACTIVATIONS. An MX block = 32 elements, each an 8-bit float sharing ONE E8M0 scale byte (value = 2^(e-127), 0xFF=NaN). Two OCP FP8 element formats: E4M3: sign(1) exp(4,bias 7) mant(3) -- NO inf; max 448; NaN = E=1111,M=111; subnormal when E=0 E5M2: sign(1) exp(5,bias 15) mant(2) -- inf at E=11111,M=00; NaN at E=11111,M!=0; subnormal when E=0 Dequant is PURE INTEGER Q16: implicit-1 mantissa (1 + M/2^m) as Q16 + a combined power-of-2 shift of (E - bias) + (scale_e - 127), sign applied. No float touches weights OR activations -> deterministic, the novel no-float treatment. Grounded: OCP MX v1.0; arXiv 2310.10537. license_tier: ORIGINAL No hw (Rule 26).
