description:
- "Extend MiniMax-M3 MXFP8 H100/H200 non-MTP sweeps to concurrency 1 on the latency rows (H100: TP8; H200: TP4 and TP8) and add full TEP coverage from conc 1 to 256 (H100: TP8+EP8; H200: TP4+EP4 and TP8+EP8, incl. a new TP4+EP4 row for 8k1k). H200 TP8+EP8 upper bound moves 512->256 (high concurrency stays covered by the TP8+EP8 dp-attn DEP rows). DEP rows unchanged"
