frank-large: cutover to flash-server v2 (abliterated Swift1.5)
Engine: halogen-flash-server 0.16.2, digest-pinned (pulled 0c61bf84). Payload: Quat3rnion qwen38-flash-next-v2-swift15-abliterated.hgn (66,687,678,464 B, sha256-verified) + REQUIRED n-gram table (51,200,246,144 B @peonist 5cc17cea) + vision tower (897,916,416 B @peonist e053f488) + shared tokenizer (6 files). Shape: 2 slots x 200192 (KV pool 400384 positions, ~10.7 GiB), MTP always-on (HALOGEN_SPEC_ADAPT=0, card-mandated), server-side sampler at the card's 1.0/0.95/20, MAX_TOK 8192 with the 65536/7200 coupled pair, vision ON. Rollback = revert this commit (27B payload stays on disk). - serve script: byte-exact gates on all three .hgn files + flat tokenizer, foreground podman run (ledger to the log file) - deploy-remote: twin gates for n-gram/vision, flashnext fetch pointer - seam: 19 tests rewritten (spec-adapt law, pool product, compaction math, render shape); full suite 362/362 green

# RUNTIME (2026-10-06, Frank): halogen-flash-server 0.16.2 — the
|
||||
# closed-source C++/HIP engine (image ghcr.io/peonist-ai/halogen-flash-server,
|
||||
# digest-pinned below) serving the Quat3rnion ABLITERATED Swift1.5 finetune
|
||||
# of peonist's Qwen3.8-Flash-Next v2 checkpoint, as a podman container under
|
||||
# a root unit, driven by scripts/serve-frank-large.sh. This CUTS OVER the
|

# 2026-10-05 halogen 27B-dense shape (censored base, DFlash2, 31.7 t/s):
|
||||
# rollback = revert the swap commit's trio; the 27B payload stays on disk at
|
||||
# /home/dank/models/halogen-qwen3.8-27b/.
|
||||
#
|
||||
# WHY THE RUNTIME MOVED WITH THE MODEL: the payload is .hgn — per its own
|
||||
# card it "will not load in transformers, vLLM, or llama.cpp". Accepted
|
||||
# consequences (Frank, 2026-10-05): TEXT-ONLY (halogen ignores the model's
|
||||
# vision encoder; the fleet's vision path is frank-small) and the CENSORED
|
||||
# base (this is a finetune of Qwen/Qwen3.8-27B, not the abliterated file —
|
||||
# refusals may return). What it buys: vendor-measured decode DFlash2 31.7
|
||||
# t/s mean (vs this endpoint's MTP 27.6-28.1 and the old halogen-era MTP
|
||||
# 26.9), prefill ~566 t/s at 32k (was ~400 on the sibling engine), 1.4-2.3x
|
||||
# wall-clock on prefill-heavy agent traffic, at HIGHER effective precision
|
||||
# (~6.32 bpw vs ~6.6 with the old W4A4 promotion — see FLAGS.md).
|
||||
# card it "will not load in transformers, vLLM, or llama.cpp" — and the v2
|
||||
# .hgn loads ONLY in the flash-server line (the old halogen engine is for
|
||||
# the 27B p1w4d file; the v2 quickstart pins flash-server). What the move
|
||||
# buys (card + live probe evidence): MTP spec decode (53-57 t/s greedy,
|
||||
# 3-10x serial), ~1,640 t/s prefill at 34k, ~72% fewer thinking tokens than
|
||||
# the censored 27B (905 mean), the ABLITERATED base (refusals should NOT
|
||||
# return), IMAGE INPUT (the v2 vision tower loads beside the checkpoint —
|
||||
# red-PNG probe verified on the card; the 27B engine ignored its encoder),
|
||||
# tool calls verified, and the native 262,144 context.
|
||||
#
|
||||
# SHAPE — the two knobs that are NOT free:
|
||||
# HALOGEN_KV_SLOTS=1 KEEPS SPECULATION ON. halogen makes batching and
|
||||
# speculation mutually exclusive: with >1 slot the drafter is disabled
|
||||
# and per-stream decode falls to serial speed (the sibling engine
|
||||
# measured 41 t/s -> 14 t/s when slots were raised, and halogen's own
|
||||
# FLAGS.md prints the same law). frank-large was already a one-session
|
||||
# endpoint under ROCmFPX (PARALLEL=1), so slots=1 is the same contract,
|
||||
# not a regression.
|
||||
# HALOGEN_SLOT_CTX=200700 (Frank's window) is the per-conversation hard
|
||||
# SHAPE — the knobs that are NOT free, with the arithmetic:
|
||||
# HALOGEN_CTX=200192 is the PER-SLOT window and the per-conversation hard
|
||||
# ceiling — a prompt over it is a 400 naming the limit, never a silent
|
||||
# truncation. KV pool = slots x slot_ctx x 64 KiB = 12.2 GiB. Budget
|
||||
# against the 121 GiB of unified memory: weights 33.4 GiB (mmap'd — page
|
||||
# cache, not anon), KV 12.2, engine working set + auto prompt cache
|
||||
# ~20-30, host baseline ~10 -> ~75-85 GiB in use. The 2026-09-16 halogen
|
||||
# era ran the same engine class on this box with LESS headroom.
|
||||
# HALOGEN_DRAFTER=2 (DFlash2) is the shipped default and the fastest
|
||||
# exact drafter on this checkpoint; the .hgn BAKES BOTH drafters (MTP +
|
||||
# DFlash2), so unlike the Flash-Next era there is no sidecar to mount
|
||||
# and no --dflash flag — the drafter is an int knob, byte-identical
|
||||
# output to greedy verification either way.
|
||||
# truncation. Harness compaction fires at 70% = 140,134, and 140,134 +
|
||||
# 57,344 (harness maxTokens) = 197,478 <= 200,192 keeps prompt + budget
|
||||
# inside the slot. models.yml contextWindow must quote 200192 or the
|
||||
# harness discovers the wall as a 400.
|
||||
# HALOGEN_KV_POOL_POSITIONS=400384 = KV_SLOTS(2) x CTX — the explicit
|
||||
# form of the engine's default, so the seam test can pin the product.
|
||||
# KV costs ~28 KiB/position (FLAGS.md) => 400,384 x 28 KiB = 10.7 GiB.
|
||||
# HALOGEN_KV_SLOTS=2 restores the w4b-era shape on this box: the MTP
|
||||
# drafter is NOT slot-locked on this engine (batching and speculation
|
||||
# coexist — DFlash-era slots>1 law does NOT carry over; the card's own
|
||||
# quickstart ships 2 slots WITH the head), so the second slot is
|
||||
# concurrent capacity, not a speculation tax.
|
||||
# Memory ledger against the box's 121.2 GiB unified (the n-gram table is
|
||||
# mmap'd page cache beside the checkpoint, not a pinned charge — the
|
||||
# card's own quickstart arithmetic does not bill it):
|
||||
# weights ~62 GiB resident + KV 10.7 + arena (HALOGEN_MAX_TOK=8192 =>
|
||||
# ~8 GiB per FLAGS.md arena formula 3.8+8.4*(MT/16384)) + vision ~2
|
||||
# = ~82.7 GiB engine-side; HALOGEN_HOST_RESERVE_GIB=20 keeps the host
|
||||
# honest; baseline co-tenancy (frank-small, ComfyUI, Caddy/observ)
|
||||
# ~10-15. ~18 GiB margin. The boot ledger is the referee — read it
|
||||
# after deploy and re-size if the engine prints a clamp.
|
||||
# HALOGEN_SPEC_ADAPT=0 is MANDATORY (card): the default adaptive policy
|
||||
# turns the MTP head off for whole requests after low acceptance and
|
||||
# HALVES decode as a result. Frank accepted the head always-on trade
|
||||
# (temp 1.0 traffic costs acceptance; the card still ships the recipe).
|
||||

# CLIENT CONTRACT deltas vs the ROCmFPX shape (the harness side lives in
|
||||
# CLIENT CONTRACT deltas vs the 27B shape (harness side lives in
|
||||
# ~/.omp/agent/models.yml):
|
||||
# * NO server-side sampler defaults: a request without temperature
|
||||
# decodes GREEDY. The harness sends temp 1.0 / top_p 0.95 via
|
||||
# extraBody, so that wire recipe is load-bearing now, not cosmetic.
|
||||
# * max_tokens defaults to 8192 PER REQUEST and INCLUDES thinking; a
|
||||
# reasoning reply over a small budget returns empty content with
|
||||
# finish_reason "length". The harness maxTokens is 57344: compaction
|
||||
# fires at 70% of 200700 = 140,490 and 140,490 + 57,344 = 197,834 <=
|
||||
# 200,700 keeps prompt + budget inside the pool (the 262144-era 65536
|
||||
# would overflow). Requests over HALOGEN_MAX_TOKENS_CAP are a 400
|
||||
# naming the cap; cap and queue timeout are COUPLED (see FLAGS.md
|
||||
# table) — do not move one without the other.
|
||||
# * response_format json_object/json_schema is a 400 (no constrained
|
||||
# decoding in this build).
|
||||
# * Thinking lands in reasoning_content — same field as the llama.cpp
|
||||
# era, so the harness compat block does NOT change. reasoning_effort
|
||||
# accepts none|low|xhigh on this build (template default xhigh); the
|
||||
# models.yml fold (high->xhigh) still applies.
|
||||
# * SERVER-SIDE SAMPLER EXISTS NOW: HALOGEN_TEMPERATURE/TOP_P/TOP_K set
|
||||
# the card's thinking recipe (1.0 / 0.95 / 20) as engine defaults, so
|
||||
# an absent temperature is no longer greedy. models.yml extraBody
|
||||
# carries the same values — consistent, not load-bearing.
|
||||
# * HALOGEN_MAX_TOK=8192 is only the DEFAULT for requests that omit
|
||||
# max_tokens; the harness always sends 57344. Requests over
|
||||
# HALOGEN_MAX_TOKENS_CAP (65536) are a 400 naming the cap. Cap and
|
||||
# queue timeout are COUPLED (FLAGS.md table): 65536 at ~10 t/s serial
|
||||
# worst case needs > 6550 s; 7200 honors it. Do not move one alone.
|
||||
# * max_tokens INCLUDES thinking; a reasoning reply over a small budget
|
||||
# returns empty content with finish_reason "length".
|
||||
# * Prompt cache is ON by default (PROMPT_CACHE=2): a follow-up turn at
|
||||
# 100k context re-prefills ~2 s instead of ~88 s cold. No pin needed —
|
||||
# unlike the 27B engine, auto-sizing fits this box's ledger.
|
||||
# * Thinking lands in reasoning_content (same as the 27B engine); the
|
||||
# v2 chat template rejects reasoning_effort outside xhigh|medium|low,
|
||||
# so the models.yml fold (high->xhigh) still applies.
|
||||
# * Vision: OpenAI image_url content parts only (the fleet's standard
|
||||
# contract). >=256 px probe images or the model answers "video".
|
||||
# * response_format json_object/json_schema unsupported in this line
