The deepseek41 architecture exists only on Luce-Org/lucebox's feat/ds41-engine branch; main rejects the checkpoint with "unsupported model architecture 'deepseek41'". Re-aim the image build at that branch and fix the launch shape, which had been copied from the V4 DS4.md recipe: - drop --ds4-fused-decode and --ds4-fused-verify-f16-kv, and use --ds4-prefill dense: V4.1's validate_model_features refuses the V4-only prefill/fused paths (layer split and --mmproj too). - --chunk 4096 (the V4.1 dense-prefill measurement point), --max-ctx 131072 (the V4.1 default window), --prefix/--prefill-cache-slots 0 as the DS41.md bring-up recipe. - drop --cache-type-k/v: the DeepSeek4 backend ignores them; the MLA compressed caches are F16 by design. - expose BOTH R9700s and set LUCE_EXPERT_STREAM_DEVICE=1, so hip:0 owns the dense weights plus the hot expert stack while hip:1 holds the streamed-expert slot cache instead of competing with it. - quadlet: 384 routed experts per layer, Engram tables, 40 layers.

# frank-primary entrypoint: exec the native luce_server with the DeepSeek V4
|
|
# launch shape for this host (2x R9700 gfx1201, 246 GiB RAM).
|
|
#
|
|
# The image's own entrypoint (server/scripts/entrypoint.sh) only forwards a
|
|
# fixed Qwen/DFlash flag set and cannot express the DS4 flags, so this unit
|
|
# bypasses it (PodmanArgs=--entrypoint) and execs the binary directly. The
|
|
# C++ server reads LUCE_* environment variables straight from the process
|
|
# environment, so no env plumbing is needed here.

#
|
|
# SOURCE BRANCH. The `deepseek41` architecture exists only on the
|
|
# `feat/ds41-engine` branch of Luce-Org/lucebox: main carries `deepseek4`
|
|
# alone and rejects this checkpoint with "unsupported model architecture
|
|
# 'deepseek41'" (server/src/common/backend_plan.cpp). The image is built from
|
|
# that branch — see serverAppConfigs-docs/LLM/frank-primary-lucebox-ds41.md.
|
|
#
|
|
# LAUNCH SHAPE (server/docs/DS41.md — the V4.1 page, not the V4 DS4.md one):
|
|
# --ds4-prefill dense the V4.1 batched prefill. The default `exact` walks
|
|
# the prompt token by token, and the V4-only modes are
|
|
# REFUSED for V4.1: `sparse`, --ds4-fused-decode,
|
|
# --ds4-fused-verify-f16-kv, layer split and --mmproj
|
|
# all fail validate_model_features at load.
|
|
# --chunk 4096 the chunk the V4.1 dense-prefill numbers were taken
|
|
# at; the runtime caps it to what the device holds.
|
|
# --max-ctx 131072 the V4.1 default window. The MLA compressed caches
|
|
# are F16 by design and stay small; --cache-type-k/v
|
|
# are ignored by the DeepSeek4 backend, so they are
|
|
# not passed.
|
|
# --prefix-cache-slots 0 --prefill-cache-slots 0
|
|
# the DS41.md bring-up recipe (the server default is
|
|
# 32 prefix slots). Lift them once capacity under load
|
|
# has been measured, not before.
|
|
#
|
|
# EXPERT PLACEMENT. 377 GiB of weights against 64 GiB of VRAM: only the dense
|
|
# weights, the compressed caches and a hot expert stack fit on hip:0, and the
|
|
# remaining routed experts are streamed out of the mmapped page cache/NVMe by
|
|
# the hybrid expert tier. LUCE_EXPERT_STREAM_DEVICE=1 moves the streamed-
|
|
# expert slot cache onto the second R9700 — it defaults to the target device,
|
|
# where it would compete with the hot stack. Both the owner stack and the
|
|
# slot cache then auto-size to their device's free memory minus the 1.5 GiB
|
|
# discrete headroom.
|
|
#
|
|
# No DSpark draft is published for DeepSeek-V4.1-Flash, so this is plain
|
|
# autoregressive decode (no --draft, no LUCE_DS4_SPEC).
