# RETIRED 2026-09-29 (operator): RL lanes are no longer used — # RL keeps training artifacts. Kept as history; use the MOPD lanes. # MiMo-V2.6-Flash-RL (Xiaomi, ~310B total / 12B-active MoE, fp8 attention + # MXFP4 experts, 1M native context, image+video+audio input) on 2x DGX Spark # with SGLang + DFlash speculative decoding. # # SGLang variant of forum thread 383968 (tonyd2wild's proven vLLM 2x recipe: # 45.6/155.8 t/s, 1.87M-token fp8 KV pool, 300K ctx, code 70.5 t/s). The # vLLM recipe needed 4 drop-in patches; the biggest (fused fp8 QKV stored # pre-sharded for TP4) is already handled natively by SGLang's MiMo-V2 # loader (same approach as vllm#57508 — the provenance of the 8x Pro recipe # working on this image family), so we run the stock a14 image. # # Image: docker-images/mimo26-spark (a14) — same build as the 8x Pro recipe: # SGLang 06008c17 base + 12 patches (MiMo-V2 day-0, DFlash, RoCEnante, FP8 # tiles) + b12x. The FP8 tile tables are tuned for MiMo's per-rank shapes — # at TP2 the shapes differ from TP8; stock fallbacks apply if a tile misses. # # Model: XiaomiMiMo/MiMo-V2.6-Flash-RL @ 5711b268 (166 GB; staged to local # NVMe on dgx1+dgx2 at ~/hf-local, which both nodes' ~/.cache/huggingface # symlinks point at — serve WITHOUT --hf-cache). The dflash/ subfolder # carries the DFlash draft weights — wired as a {{dflash}} path ref. # # KV math: 83 GB weights/rank, GMU 0.85 of 128 GB → ~25 GB/rank for the pool. # Measured at first boot (2026-09-26): pool 340,736 tokens, smoke + tool call # + needle 132K (needles at 50%/75%) all pass; code C1 71-79 tok/s (vLLM # reference: 70.5).
