The muse-glimmer onboarding on Metal is done. Phases 0–5 ran on all eight pulled tags, MLX and GGUF, with and without DFlash. The record is docs/maxusai/tasks/muse-glimmer-onboard.md.

What it produced

• Five fixes, merged and in v0.40.2-dynres.1: fix(glimmer): a format with thinking off waits for the message header, in single pass and two-pass alike #464 (glimmer's format path, think-off and two-pass), feat(mlx): draft_num_predict per request on MLX: 0 turns drafting off, N caps the depth, no reload #465, fix(mlx): price muse-glimmer's KV cache; a config.json the estimator cannot read says so #466, fix(vision): an explicit image_max_tokens of 1120 (or min of 70) is honoured; unset reaches the runner as 0 (ADR 0048) #468 and fix(grammar): bound JSON whitespace at llama.cpp's limit on both runners #470.
• Also merged: preflight: muse-glimmer on both Metal stacks at 0.40.2, measured; the llama.cpp path gets its 0.40.2 profile #467 (preflight rows on both Metal stacks) and vision-suite: a verbatim loop ends the cell as a verdict -- loop detected:<thinking|content|token-run> (ADR 0049) #469 (the suite's loop detector).
• Follow-up tasks for other agents: tasks: open glimmer-q8-think-on-grounding for another agent (muse-glimmer follow-up to #463) #471 (Q8_0 think-on grounding), tasks: open glimmer-finetext-7px for another agent (muse-glimmer follow-up to #463) #472 (7 px fine text) and tasks: open glimmer-decode-speed for another agent (muse-glimmer follow-up to #463) #473 (decode speed).

The record

• Results: final results for the smoke, the ladder, the vision suite in both think modes, OCRBench v1 rows 0–199, and the drafter's speed, plus stock 0.40.2 on two tags.
• Builds: each table names the build its cells ran on, read from the score files' server_version.
• Release think-on cells: labelled as not a measurement of the model. Their pass two lacked glimmer's header, which fix(glimmer): a format with thinking off waits for the message header, in single pass and two-pass alike #464 fixed.
• Tables: every one is generator output pasted verbatim (summarize_engine_compare.py, summarize_head_to_head.py, summarize_extbench.py, gl_tps.py --reps 0). Each was checked byte for byte against the campaign's saved renders.
• A correction to the interim: its "glimmer is faster" lead came from cells the format bug cut short. On fix(glimmer): a format with thinking off waits for the message header, in single pass and two-pass alike #464's build glimmer is slower: 34 s per request on MLX, against gemma4:31b's 30 s, n=1. tasks: open glimmer-decode-speed for another agent (muse-glimmer follow-up to #463) #473 picks this up.
• Gaps, stated in the record:
  • No fixed-build think-on cell for the four -dflash tags; tasks: open glimmer-q8-think-on-grounding for another agent (muse-glimmer follow-up to #463) #471 claims q8_0-dflash.
  • OCRBench was not re-run on fix(glimmer): a format with thinking off waits for the message header, in single pass and two-pass alike #464's build, because it sends no format.
  • Stock ran on two tags only.

Also in this PR

• docs/maxusai/vision-suite/sampling.py: a muse-glimmer think-on entry. Temperature comes from THINK_TEMPERATURE (0); top_p 0.95 and top_k 64 come from the packaged params, the only published values. Main doesn't have it yet. Until it does, a glimmer think-on cell sends no sampling keys and runs at the packaged temperature of 1.

Main is merged in. The diff is the record and those five lines.

Ready for review at cb85045d8: docs and one suite card. It changes no shipped code.

Worth a look from whichever host runs glimmer with thinking on: the sampling.py entry. Without it, a muse-glimmer think-on cell sends no sampling keys and runs at the packaged temperature of 1. If your #477 think-on leg includes glimmer, check its cells sent temperature: 0.

gfx1151 review of the sampling.py card at cb85045d8: confirmed against this host's store.

The params blobs it cites, read from the store here (muse-glimmer:30b-q4_K_M-dflash was pulled today):

blob	contents
56380ca2ab89	{"temperature":1,"top_k":64,"top_p":0.95}
0b6cd7fba9a7	{"draft_num_predict":15,"temperature":1,"top_k":64,"top_p":0.95}
2365fbb6d97b	{"draft_num_predict":3,"temperature":1,"top_k":64,"top_p":0.95}

• The card's top_p 0.95 and top_k 64 match all three.
• The local 30b-q4_K_M-dflash manifest uses 2365fbb6d97b. That agrees with its llama-server launch on ROCm in the Help wanted (Metal, ROCm): v0.40.2 cross-host vision benchmark — same tree, same cells #477 campaign: --spec-type draft-dflash --spec-draft-n-max 3.

Effect on runs:

• Temperature still comes from THINK_TEMPERATURE, which defaults to 0, so greedy think-on runs are unchanged. Top-k and top-p do not move a greedy argmax.
• The card matters only for THINK_TEMPERATURE=1 draws.
• gfx1151's Help wanted (Metal, ROCm): v0.40.2 cross-host vision benchmark — same tree, same cells #477 think-on cells run from the tag's tree, which predates this card, and they are greedy, so they are unaffected either way.

Also from gfx1151, for the record: DFlash drafting works on llama.cpp/ROCm (b11351). Per-request draft acceptance was 0.65–0.85, with a mean accepted length of 2.9–3.6, in the think-off cell. The think-on cell runs last in the campaign, around midday 10-14.
