+# caf-eemin Qwen3.8-27B ROCmI4 embedded MTP on Dankclaw
+
+> **Active 2026-08-25.** `frank-default-large` serves this model. It replaced
+> the kingjones777 ROCmFP4 STRIX MTP payload on the same port and the same
+> Strix Halo iGPU, running the new charlie12345/ROCmFPX ROCmI4 W4A4 build. See
+> [[kingjones-strix-mtp]] for the retired page.
+
+`frank-default-large` (port 7770) serves
+`cafonz/Qwen3.8-27B-ROCmI4-MTP-GGUF` (published under the public
+`eemin` namespace) from the **charlie12345/ROCmFPX** llama.cpp fork built with
+the opt-in `ROCmI4 W4A4` path. The model is `Q4_0_ROCMI4`: signed four-bit
+weights packed two per byte, quantized from the BF16 Qwen3.8-27B and carrying
+its **embedded NextN/MTP head** in the main GGUF — so there is no separate
+draft file. The native gfx1151 `v_wmma_i32_16x16x16_iu4` matrix instruction
+batch-verifies the MTP proposals for higher decode throughput.
+
+## What This Is
+
+**ROCmI4** is the GGUF weight format (signed 4-bit codes). **IU4** is the AMD
+WMMA instruction spelling that consumes them. **W4A4** means four-bit weights
+and four-bit activations during the accelerated matrix multiply. Ordinary
+one-token decode stays memory-bandwidth-bound (MMVQ); batched prompt processing
+and batched MTP target verification use the IU4 MMQ path. W4A4 is a lossy
+activation-quant speed path — treat it as a speed/quality tradeoff.
+
+The model is a conversion/quantization of `Qwen/Qwen3.8-27B` (Unsloth lineage,
+Apache-2.0), not a retrained model. It reports architecture `qwen35`
+(M-RoPE), ~27.32B params, native 262144 context, 866 tensors, ftype 108.
+

+
+## Runtime Build
+
+The stock llama.cpp build does not understand `Q4_0_ROCMI4` or the qualified
+IU4/MTP path. Use charlie12345/ROCmFPX at the pinned commit, built HIP-only
+(so the combined HIP/Vulkan scheduler cannot route the ROCmI4 tensors to
+Vulkan, which has no shader for this type) with the W4A4 option on.
+

+conversion or data change needed. The build prints
+`ROCmI4 W4A4: enabled for device 0` when the accelerated path is active.
+
+## Model Download
+
+Downloaded from the public
+`eemin/Qwen3.8-27B-ROCmI4-MTP-GGUF` repo (the card's download section still
+names the still-private `cafonz/…`; use `eemin`). Verify against the repo's
+`checksums.sha256` after download:
+
+```
+cd /home/dank/models/eemin-Qwen3.8-27B-ROCMI4-MTP
+sha256sum -c checksums.sha256
+```
+
+## Launch Profile
+
+The qualified MTP profile (from the model card and PR #94, verified on the
+live service): strict Qwen MTP, backend sampling, `n_max 16`, `p_min 0.60`.
+
+```mermaid
+graph TD
+    A[llama-server charlie12345 ROCmFPX c49ebdb<br/>ROCmI4 W4A4 enabled] --> B[load Q4_0_ROCMI4 GGUF + mmproj<br/>-ngl 999 -dev ROCm0]
+    B --> C[draft-mtp on ROCm0<br/>--spec-draft-ngl all]
+    C --> D[strict Qwen MTP<br/>n_max 16 / p_min 0.60<br/>backend sampling]
+    D --> E[Sharp chat template<br/>reasoning deepseek]
+```
+
+Key flags (see `scripts/serve-frank-large.sh`):
+
+```
+--spec-type draft-mtp --spec-mtp-strict-qwen
+--spec-draft-device ROCm0 --spec-draft-ngl all
+--spec-draft-type-k f16 --spec-draft-type-v f16
+--spec-draft-n-max 16 --spec-draft-n-min 0
+--spec-draft-p-min 0.60 --spec-draft-backend-sampling
+```
+
+Because the MTP head is **embedded**, no `--model-draft` is passed and the
+draft uses all layers on ROCm0. `--spec-mtp-strict-qwen` preserves the target
+path's greedy decisions; it does not remove the W4A4 activation approximation.
+
+### Serving settings
+
+- 262144 context (native max), 1 slot, f16 KV, context checkpoints, prompt
+  cache. Concurrent requests queue; the server never preempts a running
+  generation.
+- `-t 16 -tb 32`, batch 512 / ubatch 256 (the qualified W4A4 profile).
+- `--temp 0.7 --top-p 0.95`, reasoning on (`deepseek` puts `<think>` into
+  `message.reasoning_content`).
+- Qwen-Sharp chat template (`--chat-template-file`), `enable_thinking` +
+  `preserve_thinking` on, preserving the peg-native + deepseek shape the Pi
+  agent expects.
+- Strix Halo unified memory + native gfx1151 detection: `HSA_OVERRIDE_GFX_VERSION=11.5.1`,
+  `GGML_HIP_ENABLE_UNIFIED_MEMORY=1`.
+
+### Service
+
+- Unit: `frank-default-large.service`, port 7770
+- Script: `scripts/serve-frank-large.sh`, env `scripts/frank-default-large.env`
+
+## Tuning MTP
+
+MTP gains are content-dependent: predictable code, structured data, and lists
+accept longer drafts than creative prose. The qualified start is `n16 / p0.60`.
+If acceptance or stability is poor on another workload, lower
+`--spec-draft-n-max` to 4 or 6 and remeasure.
+
+## ubatch Benchmark
+
+Decode throughput depends on the ubatch (per-eval token batch). Run the sweep
+on 8k contexts, 512 → 4096 in steps of 512, with a fixed batch:
+
+```
+STOPSVC=1 ./scripts/bench-ubatch-rocmi4.sh
+```
+
+The script stops `frank-default-large` for a clean GPU, boots one server
+instance per ubatch on a scratch port, reads authoritative `print_timing` tok/s,
+and restarts the service. See [[frank-default-large-benchmark]].
+
+## Known Issues
+
+1. **gfx1151 only** for the W4A4 path. Other GPUs fall back to exact int8 MMQ.
+2. **Memory pressure:** the model is 13.5 GiB. Under `--no-mmap` with full
+   offload it needs the whole tensor set at once; leave room in the 64 GiB
+   unified pool (rocm-smi figure). Do not run a bench with the live service up
+   or it OOMs at load.
+3. **`Q4_0_ROCMI4` + MTP flags need the ROCmFPX fork**; stock llama.cpp may
+   reject the file or drop the optimized path.
+4. **W4A4 is lossy** (+~5.4% perplexity vs exact int8). Opt-in speed path.
+
+## Measured Results (qualification)
+
+From the model card, gfx1151, pinned build, W4A4 + strict MTP-16:
+
+| Result | Value |
+|--------|-------|
+| HumanEval pilot, W4A4 IU4 (mean) | 49.40 tok/s |
+| Full HumanEval, W4A4 (mean / median) | 44.39 / 45.23 tok/s |
+| HumanEval / HumanEval+ pass@1 | 94.5% / 91.5% |
+| Non-speculative tg128 | ~13.8 tok/s |
+
+Local smoke test 2026-08-25 on the iGPU: model loaded, strict-MTP active,
+draft acceptance 0.74 (mean 7.67), generation ~25 tok/s at a small output.
+The ubatch sweep above gives the production ubatch choice.
