Where it came from

  • Repo / file: unsloth/Qwen3.5-9B-MTP-GGUF / Qwen3.5-9B-Q8_0.gguf (9.79 GB on HF's listing). Fetched by models/qwen3.5-9b-mtp/get.sh with 6-range pget.sh; size 9332 MiB in 6 parts. Done 10:57Z.
  • What it is: the same weights as the plain build plus an embedded MTP (nextn) draft head; the script comment says the plain and MTP builds carry identical weights, "so this is a matched-pair speculation A/B" rather than a model comparison, and warns that llama.cpp "silently ignores the head" without spec-type = draft-mtp. Verified by reading GGUF tensors: 4 nextn tensors in the MTP Q8_0 against 0 in the plain Q8_0. Parameter count 9,197,093,888 against 8,953,803,264.
  • Size: llama-bench tensor model_size 9,775,091,712 B; the file's byte size is not on record. sha256 not on record.
  • Who asked: the assistant offered it as a question; Alan answered "Yes, both quants with MTP".

How it was served

Seats held: none. No MTP speculation run on this file is on record: the only draft-mtp commands on record are for other models.

Decisions

  • Downloaded on 2026-08-23 for a speculation A/B.
  • Pre-registered expectation (2026-08-23 12:36Z): because Q4 and Q8 decoded at the same speed, the 9B "isn't bandwidth-bound at all", so speculation should win on it, and the matched MTP pair was "the cleanest speculation A/B available anywhere". The test was "a cheap experiment when the box frees up" and the assistant was "happy to leave it queued"; it was never run. That reasoning was later undercut, since the equality came from K-quant unpacking cost, not an overhead floor.
  • Deleted 2026-09-07 17:36Z in Alan's disk sweep ("Go for it"). The assistant had listed the plain and MTP directories as near-identical duplicates; the delete script filed the directory under "superseded / measured-and-rejected", which misdescribes it: nothing had been measured with the head.

What went wrong

  • Mislabelled deletion reason, as above: "measured-and-rejected" but never measured.
  • Standing checks: no suite ran, so partial-run, build-stamp and flag checks do not apply.
