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).

# frank-large — gufo (gufo-org/gufo) serving

# Swift-1.5-Qwen3.8-27B-Uncensored (abliterated) on the Strix Halo iGPU.

#
|
|
# These are the tunables read by scripts/serve-frank-large.sh. The flag
|
|
# list is owned by the serve script; this file only sets fleet values.
|
|
#
|
|
# DO NOT name a new tunable TEMP, HOST or GPU_MAX_HEAP_SIZE: the HIP
|
|
# runtime reads those bare (the 2026-08-13 TEMP incident). HOST is the one
|
|
# exception because the serve script itself consumes it for --host.
|
|
|
|
# The target payload (scripts/download-frank-large-q4.sh): the serve script
|
|
# refuses to start without the main GGUF and the DFlash2 drafter.

# 2026-10-01 swap (Frank): unsloth/Qwen3.8-27B-GGUF:UD-Q4_K_XL, 16.35 GiB,
|
|
# replacing ajgazin's abliterated Swift-1.5 UD-Q8_K_XL (29.3 GiB). Two
|
|
# consequences worth knowing at a glance:
|
|
# * this is the VANILLA (non-abliterated) Qwen3.8-27B — the endpoint is no
|
|
# longer uncensored, which was one of the reasons the Swift payload was
|
|
# chosen on 2026-09-28;
|
|
# * ~13 GiB of weights became available for KV, which is what makes four
|
|
# full-sized f16 sessions fit.
|
|
# gufo needs no template for either: its Qwen renderer is compiled in.
