# DeepSeek-V4-Flash-Vision-Exp on 2× GB10 — aidendle94 sparkrun vision image.
#
# aiden's vision guide (https://aidenle.com/recipes/deepseek-v4-flash-vision-4x-dgx-spark/)
# translated to 2× Spark / DCP1 (his "DSpark, DCP1" profile: 73.8-75.2 tok/s at
# TP4/DCP1; on 2x expect roughly half). His production lane ships DCP2 + DSpark
# (66-71 tok/s, 3.5M KV); DCP flags omitted here — DSpark runs fine under DCP1.
#
# Image: dsv4-flash-vision:local (our plugin overlay on aiden's
# production-3.76.1 base — see dsv4-flash-vision/ UPSTREAM.md). Aiden's
# production-3.72-vision tag is the published 4x stack; running it under our
# launcher needs his env-script contract (NODE_RANK/MASTER_ADDR/NCCL_IB_*
# required by /usr/local/bin/deepseek-v4-flash-2x-spark-entrypoint →
# /opt/vllm-src/serve-ds4-flash-spark.sh) — a dedicated integration pass,
# tracked as follow-up. The overlay image carries the equivalent flags:
# draft greedy + FULL_AND_PIECEWISE graphs + capture cap via the envs below.
#
# Weights: deepseek-ai/DeepSeek-V4-Flash-Vision-Exp (cached; ~84 GiB/node at
# TP2 via ~/dsv4vision-hf NVMe copies). Draft heads ship in the checkpoint
# (mtp.*) — no extra download.
#
# DSpark: k=6, greedy draft, acceptance 3.5-3.8 tokens/step. Acceptance is the
# DCP correctness signal; equal DSpark-DCP1 numbers here = draft sees full ctx.
# max-cudagraph-capture-size = seqs × (spec tokens + 1) = 8 × 7 = 56.
#
# VISION_MHC=1 follows aiden's production profile; our plugin lane keeps
# VLLM_USE_B12X_MHC=0 (checkpoint rms_norm_eps 1e-20 vs fused Gram kernel's
# 1e-6 — upstream README). If this boot asserts on the mHC kernel, flip to 0.
#
# Boot markers: vision plugin registered → "Model loading took ~84 GiB" →
# "GPU KV cache size" ≈ 1.25M → "Application startup complete".
