One file — the **best speed/quality balance** in ROCmFP4 for Strix Halo. It keeps the two quality levers that are actually *felt* — genuine **f16 token embeddings** (from BF16) and a **Q6_K output head** — on the fast single-scale `q4_0_rocmfp4_fast` body + a general+code-calibrated imatrix + the **grafted MTP draft head**. Repo also bundles the **[`mmproj-F32.gguf`](./mmproj-F32.gguf)** Qwen3-VL vision projector and **[`chat_template.jinja`](./chat_template.jinja)** (froggeric's unified Qwen3.6 template — tool calls + inline `<|think_off|>`/`<|think_on|>` + vision).

Qwen3-VL lineage — vision works via the **bundled `mmproj-F32.gguf`** projector with `--mmproj` (same LLM GGUF, no separate vision model). It's the Qwen3-VL projector (`projection_dim 5120`, matches this model's hidden size), shipped in this repo:

```bash
  --mmproj mmproj-F32.gguf \
  --image-min-tokens 1024     # REQUIRED — Qwen-VL needs >=1024 image tokens or it misreads fine detail
```

Without `--image-min-tokens 1024` the server feeds too few image tokens and the model **describes images incorrectly** (right gist, wrong detail — the server even logs a warning at load). Verified on this model: a code label misread at default tokens read correctly once the flag was set.

<div style="border:1px solid currentColor; padding:8px 13px; font-family:ui-monospace,'SF Mono',Consolas,monospace; font-size:12px; margin:12px 0; opacity:0.85;">
<b>NOTE //</b> thinking model → for one-shot image Q&amp;A use <code>&lt;|think_off|&gt;</code> (the bundled <code>chat_template.jinja</code>) or allow enough tokens, else the answer can come back empty. With <code>--mmproj</code> loaded the server disables the <code>--cache-reuse</code> feature (it logs <i>"cache_reuse is not supported by multimodal"</i>); whether ordinary cross-turn caching still helps with vision isn't something we've benchmarked.
</div>

<div style="font-family:ui-monospace,'SF Mono',Consolas,monospace; font-weight:800; font-size:14px; letter-spacing:2px; text-transform:uppercase; border-bottom:2px solid currentColor; padding-bottom:5px; margin:26px 0 12px;"><span style="color:#ea580c;">04</span> · PERFORMANCE &amp; QUALITY</div>

**This is the best speed/quality balance in ROCmFP4 — by design, not the absolute fastest.** The two quality levers that are actually *felt* — genuine **f16 token embeddings** and a **Q6_K output head** — sit on the fast single-scale `q4_0_rocmfp4_fast` body. The alternatives we'd otherwise reach for (an all-dual-scale body, selective higher-precision tensors) buy a KL improvement that sits *inside the measurement noise* while costing decode speed — so the fast body is the right point. A leaner Q5-embedding build is a few tok/s faster but degrades the one lever you notice; we keep full f16 embeddings.

We ran this exact sweep in full on the sibling **[Qwen3.6-27B base card](https://huggingface.co/plunderstruck/Qwen3.6-27B-MTP-ROCmFP4-GGUF)** — every rocmfp4 lever measured by **KL divergence vs the BF16 reference** plus `llama-bench` decode. The frontier there is the same shape it is here: the fast body + f16 emb + Q6 head is the balance point, all-dual-scale and selective higher-precision land inside the noise, and the dynamic K-quant is the fidelity ceiling that rocmfp4's FP4 can't out-allocate. See that card for the numbers and the full experiments table; OBLITERATED follows the same recipe.

<div style="border:1px solid currentColor; padding:8px 13px; font-family:ui-monospace,'SF Mono',Consolas,monospace; font-size:12px; margin:12px 0; opacity:0.9;">
<b>WANT MAXIMUM FIDELITY INSTEAD OF SPEED?</b> There's no Unsloth UD-quant of this abliterated model, so for the last bit of fidelity grab a <b>Q6_K / Q8 GGUF of the base abliterated model</b> from <a href="https://huggingface.co/OBLITERATUS/Qwen3.6-27B-OBLITERATED"><b>OBLITERATUS/Qwen3.6-27B-OBLITERATED</b></a>. Those higher-bit GGUFs run on this same fork — trading lower KL for slower decode. We optimize for throughput in ROCmFP4; if you want fidelity over speed, that's the one to grab.
</div>

**Grafted MTP head — measured.** OBLITERATED ships **no** MTP head, so we transplanted a `nextn` block from a **Qwen3.6-27B-MTP BF16 donor** (output-lossless — the draft head only affects *speed*, never the tokens). Because OBLITERATED is abliterated *from* that same base, the borrowed head tracks it closely. Measured on the ROCmFP4 fork (`llama-server --spec-type draft-mtp`, f16 KV on target **and** drafter, 4 prompt types, temp 0.6):

**~2.1× faster decode** (14.1 → 29.5 t/s) at **67.7%** token acceptance — high on structured/predictable text, lower on freeform prose, the profile of a borrowed (not natively-trained) head. KV is f16 on both the main model and the draft; the draft head is kept at 4-bit ROCmFP4.

**The imatrix WINS here — measured.** Quantized **with** an importance matrix from a public general+code calibration mix (Kalomaze `groups_merged` + froggeric `code`/`technical`, via [`froggeric/imatrix`](https://huggingface.co/datasets/froggeric/imatrix)).

For OBLITERATED the imatrix is a **clean win** on every robust metric — it behaves like its base Qwen3.6-27B, not like the dense [Qwopus-Coder](https://huggingface.co/plunderstruck/Qwopus3.6-27B-Coder-MTP-ROCmFP4-GGUF) (where the same recipe *worsened* code-PPL — but that was a *code* metric; this is a general model measured on general text). Always measure; we did.

<b>NOTE //</b> Quality scope: the KL/PPL above is a fidelity-vs-BF16 measurement on ~20 K tokens of held-out general text, <b>not</b> an absolute benchmark. The MTP head is <i>borrowed</i> (not trained on this model) — output-lossless, affecting speed only. Experimental research build for AMD Strix Halo — hardware/driver/prompt-sensitive. <b>Not</b> native FP4 tensor-core execution.

```bash
# 0) convert the abliterated safetensors -> BF16 GGUF
python convert_hf_to_gguf.py OBLITERATED-27b/ --outtype bf16 --outfile OBLITERATED-BF16.gguf

# 1) ** GOTCHA ** OBLITERATED's config declares `mtp_num_hidden_layers: 1` but ships NO MTP weights,
#    so the convert labels it block_count=65 with only 64 real layers -> "missing tensor blk.64.*" on load.
#    The real model is 64 layers; the donor's nextn becomes the new blk.64.

# 2) graft a Qwen3.6-27B nextn head onto blk.64, then set block_count = 65
python inject_mtp_40b.py --target OBLITERATED-BF16.gguf --donor Qwen3.6-27B-MTP-BF16.gguf \

```

A 4-bit Strix-Halo quant of OBLITERATUS's abliterated 27B. The abliteration (refusal-direction removal + source interpolation) is upstream work; we add the ROCmFP4 quant, genuine f16 embeddings, and a grafted MTP head.
