Both b11030 serve scripts never passed --metrics, so /metrics answered 501 and Prometheus could not scrape frank-large (silently down since its deploy) or frank-primary. frank-primary also gets -lv 4 (VERBOSITY env tunable, default 4) for the full per-buffer load breakdown.

# Serve unsloth/Qwen3.8-Flash-Next-GGUF at Q8_0 as frank-primary on
|
|
# Dankserver's two Radeon AI PRO R9700s (gfx1201), using the unsloth
|
|
# b11030-mix prebuilt (ROCm gfx120X, bundled runtime).
|
|
#
|
|
# Shape: one stream, the model's full 262144 context, all non-overridden
|
|
# tensors on the GPUs (--n-gpu-layers 999 across both cards), with the
|
|
# routed experts and the 51B-param n-gram embedding table computed in host
|
|
# RAM via --override-tensor (the x4-pair law: streaming over PCIe loses,
|
|
# computing in RAM does not care). mmap stays ON (the PLE table must stay
|
|
# page-cache-backed; --no-mmap forces it into anonymous memory and the
|
|
# cgroup kill is silent).
|
|
#
|
|
# Spec chain: draft-mtp (the shared Q8_0 head, loaded via -md) chained with
|
|
# the draftless ngram-mod matcher. The shared head borrows the target's
|
|
# embedding tensors, which is why per_layer_token_embd.weight must be
|
|
# CPU-resident (see frank-primary.env). depth 2.
|
|
#
|
|
# Vision: the BF16 projector, loaded explicitly via --mmproj (this build
|
|
# never autoloads projectors — the frank-medium 2026-09-17 trap: a server
|
|
# started without it comes up healthy and text-only, and answers image
|
|
# requests with 500).
|
|
#
|
|
# Template: the GGUF's embedded chat template via --jinja. The Qwen3.8
|
|
# family template gates reasoning_effort to {xhigh, medium, low} — the
|
|
# harness folds its levels onto that set in models.yml
|
|
# (reasoningEffortMap). If the embedded template ever falls back to
|
|
# peg-native and bloats prompts (~73,600 tokens for a ~250-token request),
|
|
# switch to --chat-template-file scripts/qwen-sharp-v22.4.0.jinja the way
|
|
# frank-large does.
|
|
#
|
|
# Tunables come from frank-primary.env unless FRANK_PRIMARY_ENV_FILE
|
|
# overrides it; anything not set there falls through to the defaults below.
