# kingjones Qwen3.8-27B ROCmFP4 STRIX MTP on Dankclaw

> **Active again 2026-09-01.** The kingjones ROCmFP4 STRIX MTP payload is
> restored as `frank-large` after the Q8_0 AGENT experiment. The Q8_0
> model was retired because it crashed before serving. The Q6 AGENT model,
> standalone MTP draft, Q8 projector, and PromptForge runtime are now active.

> This page documents the active model and its runbook.

`frank-large` (port 7770) serves
`Qwen3.8-27B-Uncensored-ROCmFP4-STRIX-MTP` from `kingjones777` on Hugging
Face. It is a **dense** Qwen3.8-27B, abliterated (uncensored), quantized to
the ROCmFP4 Q6 AGENT format (ftype 114). The MTP speculative head ships as
a **separate** Q4_0 draft GGUF, so a bundled-head auto-detect does not apply
here; the head is loaded with `--model-draft`.

## Model Files

The card ships six text files plus the vision projector. The service uses
the Q6 AGENT file (requested for the fleet), the separate MTP draft head
and the Q8 vision projector (`mmproj-Qwen3.8-27B-Q8_0.gguf`).

| File | Size |
|------|------|
| `Qwen3.8-27B-Uncensored-Q6_0_ROCMFPX_AGENT.gguf` | 23.15 GiB |
| `mtp-Qwen3.8-27B-Q4_0.gguf` (draft head) | 1.56 GiB |
| `mmproj-Qwen3.8-27B-Q8_0.gguf` (vision) | 0.59 GiB |

Store the files under `/home/dank/models/kingjones-Qwen3.8-27B-STRIX-MTP/`.

## Speculative Decoding

Dense model, so the finding measured on the dense Qwen3.8 family holds:
**MTP alone at `--spec-draft-n-max 4` is the knee**. ngram under MTP hurts
(measured -4 to -5 t/s on the v3; see [[ciru-activefpx-promptforge]]). The
draft head is a separate file loaded via:

```
--spec-type draft-mtp
--model-draft mtp-Qwen3.8-27B-Q4_0.gguf
--spec-draft-n-max 4
--spec-draft-n-min 0
--spec-draft-p-min 0.0
```

The draft head loads on `ROCm1` with full offload (`--spec-draft-ngl 999`)
and f16 KV.

## Launch Excerpt

The key flags on the CIRU ROCmFPX runtime:

```
llama-server \
  -m Qwen3.8-27B-Uncensored-Q6_0_ROCMFPX_AGENT.gguf \
  --mmproj mmproj-Qwen3.8-27B-Q8_0.gguf \
  --chat-template-file chat-template.jinja \
  --chat-template-kwargs '{"enable_thinking":true,"preserve_thinking":true}' \
  -ngl 999 -dev ROCm0 -c 196608 -np 1 \
  -b 8192 -ub 8192 -ctxcp 32 \
  --spec-type draft-mtp --model-draft mtp-Qwen3.8-27B-Q4_0.gguf \
  --spec-draft-ngl 999 --spec-draft-n-max 4 \
  -fa on --no-mmap --cache-type-k f16 --cache-type-v f16
```

## Known Issues

1. **GPU only**: Vulkan, CUDA, and CPU cannot load these files.
2. `--spec-draft-n-max` defaults to 16; set 4.
3. `reasoning_effort: "none"` throws in the Qwen API. Use
   `enable_thinking: false` instead.
4. Small `max_tokens` with thinking on returns empty `content`. The Sharp
   template drives thinking on by default (effort medium).
5. `preserve_thinking:true` (in `chat_template_kwargs`) keeps `<think>`
   blocks in recorded assistant messages. `preserve_thinking:false` strips
   them. See [[deployment]] for the chat_format/reasoning_format pairing
   (`peg-native` + `deepseek`) the Pi agent expects from this endpoint.
