Frank 8029119b19 frank-large: Q4_K_XL payload + 4 x 163840 sessions (f16 KV)
Frank's call. Payload: ajgazin's abliterated Swift-1.5 UD-Q8_K_XL (29.3 GiB,
SWIFT OPEN LICENSE) -> unsloth/Qwen3.8-27B-GGUF UD-Q4_K_XL (16.35 GiB,
sha256 3f227079...b01e, vanilla/Apache-2.0). NOTE: the endpoint is no longer
uncensored — that was one of the reasons for the Swift payload on 2026-09-28.

New fetcher scripts/download-frank-large-q4.sh (no auth header: repo is public
and ungated; size + sha256 verified after transfer). The speculative drafter
and its fetcher are unchanged.

Shape: --sessions 4 --context 163840 with unquantized KV. gufo exposes no KV
quantization lever (execution_policy.hpp pins kv_cache_storage to kFp16), so
f16 is inherent.

KV arithmetic: f16 KV = 64 KiB/token (16 full-attention layers x 4 KV heads x
256 head_dim x 2 x 2B; the other 48 layers are linear-attention with a
per-sequence fp32 state). 4 x 163840 = 655,360 tokens = 40.0 GiB KV, each
session exactly 10 GiB. Budget ~62 GiB of the 114 GiB GTT.

Seam retargeted (FETCH -> the q4 script, TARGET_STUB, context/sessions pins).

# Serve Swift-1.5-Qwen3.8-27B-Uncensored (abliterated) as frank-large on
# Dankclaw's Strix Halo iGPU (gfx1151), using gufo (gufo-org/gufo) — the
# inference engine built specifically for this hardware.
#
# Runtime: /home/dank/GitPackages/gufo-v0.1.1/bin/gufo, built from source
# against the host ROCm by scripts/build-gufo.sh. It replaced the stock
# llama.cpp prebuilt (unsloth b11030) on 2026-09-28; port, alias and client
# contract did not move.
#
# Payload: ajgazin/Swift-1.5-Qwen3.8-27B-Uncensored-Dynamic-MTP-GGUF's
# UD-Q8_K_XL, fetched by scripts/download-frank-large-swift.sh. It replaced
# unsloth/Qwen3.8-27B-GGUF:UD-Q8_K_XL on 2026-09-28. The two are structurally
# interchangeable for this engine — same `qwen35` architecture, the same 866
# tensors in the same order, the same per-tensor Q8_0/F32/BF16 layout, the
# same MTP head at blk.64 — so the swap needed no engine change. The fine-tune
# is abliterated (uncensored) and carries the SWIFT OPEN LICENSE 1.0, which
# is not an OSI licence.
#
# Shape: one session, full 262144 context (the model's native window). The
# 27B dense weights (16.35 GiB at UD-Q4_K_XL) + the DFlash2 drafter (1.07) + KV +
# compute buffers fit the iGPU's GTT aperture (~114 GiB); a load at this
# context measured 66.5 GiB of the 116.7 GiB device.
#
# Spec method: DFlash2 (a block-diffusion drafter), gufo's adaptive block
# policy, capped at DRAFT_TOKENS proposals per step. The drafter is the
# z-lab Qwen3.8-27B-DFlash2-Q4_K_M and it has a sliding window of 2048
# (small draft KV). It is UNCHANGED by the model swap and still lives beside
# the previous target, which is why DRAFTER_DIR is its own tunable.
#
# Sampling: greedy (--temperature 0) server-side, as every frank-large has
# served. The harness overrides it per request via extraBody (1.0 / 0.95 /
# top-k 20).
#
# Template: gufo compiles the official Qwen Jinja into the binary and takes
# NO --chat-template-file — and it is not a Jinja engine at all
# (src/models/qwen/chat_template.cpp is a hand-written C++ renderer), so the
# fleet's scripts/qwen-sharp-v22.4.0.jinja cannot be supplied to it. That law
# was given up when this endpoint moved to gufo on 2026-09-28, by decision:
# the terse system-prompt injection, the in-band <|think_*|> control, the
# json|xml tool_call_format switch and the tool-argument truncation are all
# absent. gufo's own renderer keeps the effort instruction strings and
# preserve_thinking, which are the parts the harness depends on. Accepted
# 2026-09-28; recovering the terse prompt from the client side is the
# cheapest partial restore.
#
# Text-only: gufo auto-discovers a mmproj beside the model and this payload
# has none (the base repo ships one separately, unused), so the endpoint
# stays text-only.
#
# Tunables come from frank-large.env unless FRANK_LARGE_ENV_FILE overrides
# it; anything not set there falls through to the defaults below.
