# DeepSeek-V4-Flash-Vision-Exp on 2× GB10 — aiden image, flag route.
#
# aidendle94/sparkrun-vllm-ds4-gb10:production-3.72-vision, TP2 over ds4.
# His production 2x DSpark-6 profile translated to our launcher shape: his
# own serve line (moe/linear b12x, B12X_MLA_SPARSE attention, fp8 KV, block
# 256, DSpark-6 greedy, graphs FULL_AND_PIECEWISE) as plain flags — the
# image's BAKED-IN entrypoint is his env-script (which doubles our tail args
# if left in place), so the recipe sets entrypoint = ["vllm","serve"] and one
# mods line, which makes the launcher wrap everything in `--entrypoint sh -c`
# and exec our tail directly with the image's system vllm — which IS his
# multimodal wheel (the dist-packages vllm here carries the DeepseekV4 vision
# wrap; the earlier "not multimodal" 400s came from OUR overlay image, not
# this one).
#
# Weights from the SHARED NAS HF cache (all 4 nodes mount nas.lan:/sna as
# /mnt/nas; the repo's refs/main resolves offline). 2x reference: his 4x
# DCP1 DSpark profile is 73.8-75.2 tok/s; 2x should sit below that.
# Boot markers: "Model loading took ~82 GiB" → "GPU KV cache size" →
# "Application startup complete". Smoke: 47*83 → 3901 + image_url ask.
