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/Qwen3.8-27B-GGUF:UD-Q8_K_XL as frank-large on
|
|
# Dankclaw's Strix Halo iGPU (gfx1151), using stock llama.cpp
|
|
# (mainline, the unsloth b11030 prebuilt).
|
|
#
|
|
# Runtime: /home/dank/GitPackages/unsloth-llama-b11030/llama-server
|
|
# (mainline, ROCm gfx1151 prebuilt). The build supports the qwen3_5
|
|
# architecture and the DFlash2 drafter (llama_model_qwen35,
|
|
# llama_model_dflash, common_speculative_impl_draft_dflash).
|
|
#
|
|
# Shape: one stream, full 262144 context (the model's native window), all
|
|
# layers on the iGPU (--n-gpu-layers 999). The 27B dense model (31.46 GiB GGUF) + the
|
|
# DFlash2 drafter (1.14 GiB) + q8_0 KV (~8.6 GiB) + compute buffers fits the
|
|
# iGPU's GTT aperture (~114 GiB).
|
|
#
|
|
# Spec method: DFlash2 (a block-diffusion drafter) at depth 4. The drafter
|
|
# has a sliding window of 2048 (small draft KV, ~40 MiB).
|
|
#
|
|
# KV: q8_0 quantized (--cache-type-k q8_0 --cache-type-v q8_0). The unsloth b11030
|
|
# build does not support fp8 KV (allowed: f32/f16/bf16/q8_0/q4_0/q4_1/iq4_nl/q5_0/
|
|
# q5_1); q8_0 is the highest-precision 8-bit option and preserves the ~8 GiB footprint.
|
|
#
|
|
# Text-only (no mmproj) — matching the prior frank-large.
|
|
#
|
|
# The Qwen3.8 family template keeps prior thinking blocks across turns when
|
|
# preserve_thinking is set; pass --jinja and the kwarg so multi-turn agents
|
|
# do not lose the trail. The template gates reasoning_effort to {xhigh,
|
|
# medium, low} — the harness folds its levels onto that set in models.yml
|
|
# (reasoningEffortMap).
|
|
#
|
|
# Tunables come from frank-large.env unless FRANK_LARGE_ENV_FILE overrides
|
|
# it; anything not set there falls through to the defaults below.
