# Muse-Glimmer-30B ROCmFPX GGUF

ROCmFP4 and ROCmFP8 builds of
[meta-models/Muse-Glimmer-30B](https://huggingface.co/meta-models/Muse-Glimmer-30B),
targeted and tested on AMD Strix Halo (`gfx1151`). Rawr. 🦖

At publication time, a Hub search returned no other Muse Glimmer ROCmFPX
repositories. These are custom ROCmFPX formats, not ordinary llama.cpp Q4/Q8
files; read the compatibility section before downloading.

> **Experimental runtime required:** these GGUFs need a patched build of
> [charlie12345/ROCmFPX](https://github.com/charlie12345/ROCmFPX). Stock
> llama.cpp does not implement the ROCmFP4/ROCmFP8 tensor layouts, while the
> pinned ROCmFPX base predates Muse Glimmer support. Apply the included
> [`ROCmFPX-Muse-Glimmer.patch`](https://huggingface.co/vmlinux/Muse-Glimmer-30B-ROCmFPX-GGUF/blob/main/ROCmFPX-Muse-Glimmer.patch)
> to ROCmFPX commit `00d54526e…`, then build that
> checkout. The patch adds the upstream Muse text, vision, and DFlash support,
> ports it to ROCmFPX's older APIs, supplies the FP16 sparse-attention mask
> required by its multimodal flash-attention path, and backports the DFlash
> injected-cache rotation fix required when using quantized KV caches.

¹ End-to-end target measurement with `Muse-Glimmer-30B-ROCmFP4.gguf`, DFlash
enabled, and a six-token draft window. These are three-run means; the main-model
and projector rows are the earlier short smoke tests described under Validation.

Suggested choices:

- **ROCmFP4:** default Strix Halo speed/quality build. Fast FP4 body, dual-scale
  FP4 attention K/V, and Q6_K token embeddings.
- **ROCmFP4-Q6-QUALITY:** coherence-biased build. Dual-scale FP4 throughout the
  body with Q6_K token embeddings.
- **ROCmFP8:** high-fidelity 8.25-bpw reference build.
- **DFlash ROCmFP4:** recommended drafter on Strix Halo. It is smaller and was
  slightly faster than the FP8 drafter in the measured six-token configuration.
- **DFlash ROCmFP8:** higher-precision drafter reference; useful for comparing
  acceptance behavior and tuning on other hardware.

The BF16 projector works with all three text models.

## iMatrix

Both FP4 models use the same GGUF importance matrix:

- 500 chunks × 512 tokens (approximately 256k calibration tokens)
- 416 tensor importance entries consumed by each quantizer
- varied narrative/general-language calibration corpus
- checkpoints saved every 100 chunks

`Q8_0_ROCMFPX` does not consume importance weights, so the FP8 reference was
intentionally built without an iMatrix.

The two DFlash drafters were quantized directly from Meta's official assistant
checkpoint without an iMatrix. Their role is proposal generation: every draft
is verified by the main model, so drafter quantization changes acceptance and
speed rather than bypassing the target model's output decision.

## Compatibility

These files use experimental ROCmFPX tensor types and **will not load in stock
llama.cpp**.

The validated runtime was built from:

- [ROCmFPX](https://github.com/charlie12345/ROCmFPX) base commit
  `00d54526e24e3aba4c76474e3147cbf9c7cc034c`
- upstream llama.cpp Muse support commit
  [`62bf73d25c53b8161f8a22894d4f90c4aebbd7d0`](https://github.com/ggml-org/llama.cpp/commit/62bf73d25c53b8161f8a22894d4f90c4aebbd7d0)
- small compatibility adaptations for the older ROCmFPX chat, model, and
  multimodal APIs
- the upstream DFlash quantized-cache rotation fix, adapted to this older graph
  API; without it, Q4_0 draft KV caches load but produce near-zero acceptance

[ROCmFPX-Muse-Glimmer.patch](https://huggingface.co/vmlinux/Muse-Glimmer-30B-ROCmFPX-GGUF/blob/main/ROCmFPX-Muse-Glimmer.patch)
contains the complete patch against the pinned
ROCmFPX base. The runtime was built with ROCm and Vulkan backends; the reported
generation tests used `ROCm0` on `gfx1151`.

Minimal runtime setup:

```bash
git clone https://github.com/charlie12345/ROCmFPX.git
cd ROCmFPX
git checkout 00d54526e24e3aba4c76474e3147cbf9c7cc034c

hf download vmlinux/Muse-Glimmer-30B-ROCmFPX-GGUF \
  ROCmFPX-Muse-Glimmer.patch \
  --local-dir /tmp/muse-glimmer-rocmfpx
git apply /tmp/muse-glimmer-rocmfpx/ROCmFPX-Muse-Glimmer.patch

BUILD_DIR=build-muse-rocmfpx \

CMAKE_HIP_COMPILER=/opt/rocm-7.2.0/lib/llvm/bin/clang++ \
GGML_HIP_ROCWMMA_FATTN=OFF \
./scripts/build-strix-rocmfp4-mtp.sh
```

Adjust `CMAKE_HIP_COMPILER` for the installed ROCm version. The resulting
runtime binaries are under `build-muse-rocmfpx/bin/`. The patch must be applied
to the exact pinned commit; `git apply --check` was verified before publishing.

## Validation

All three files completed clean, single-turn ROCm generation with every layer
offloaded. The projector completed an end-to-end image test and correctly
identified the test image as a folder icon.

| Model | Prompt processing | Token generation |
| --- | ---: | ---: |
| ROCmFP4 | 113.7 tok/s | 14.9 tok/s |
| ROCmFP4-Q6-QUALITY | 39.0 tok/s | 14.0 tok/s |
| ROCmFP8 | 96.7 tok/s | 7.8 tok/s |
| ROCmFP4 + BF16 projector | 81.7 tok/s | 14.9 tok/s |

These are short smoke-test measurements, not a formal benchmark. Host: AMD
Strix Halo `gfx1151`, 128 GiB unified memory, ROCm backend, 1,024-token text
context (2,048 for vision).

### DFlash benchmark

The additive DFlash benchmark used the default ROCmFP4 target, batch size 1,
greedy decoding, three text prompts, 256 generated tokens per prompt, a
2,048-token context, flash attention, full `ROCm0` offload, and Q4_0 target and
draft KV caches. Values are arithmetic means of the three runs.

| Mode | Draft window | Prompt t/s | Output t/s | Speedup | Output range | Weighted draft acceptance |
| --- | ---: | ---: | ---: | ---: | ---: | ---: |
| No speculation | — | 73.7 | 13.7 | 1.00× | 13.7–13.7 | — |
| DFlash ROCmFP4 | 6 | 65.5 | **28.3** | **2.07×** | 24.3–31.8 | 35.8% (519/1,448) |
| DFlash ROCmFP8 | 6 | 65.1 | 27.2 | 1.99× | 24.1–33.0 | 35.7% (519/1,454) |
| DFlash ROCmFP4 | 15 | 65.6 | 24.6 | 1.80× | 18.5–30.7 | 17.1% (543/3,171) |
| DFlash ROCmFP8 | 15 | 65.3 | 26.3 | 1.92× | 19.2–34.6 | 19.5% (563/2,891) |

Raw llama.cpp throughput lines for all 15 benchmark runs:

| Mode | Window | Prompt 1 `[Prompt \| Output]` | Prompt 2 `[Prompt \| Output]` | Prompt 3 `[Prompt \| Output]` |
| --- | ---: | ---: | ---: | ---: |
| No speculation | — | 55.3 t/s \| 13.7 t/s | 83.5 t/s \| 13.7 t/s | 82.4 t/s \| 13.7 t/s |
| DFlash ROCmFP4 | 6 | 50.3 t/s \| 28.8 t/s | 73.7 t/s \| 24.3 t/s | 72.5 t/s \| 31.8 t/s |
| DFlash ROCmFP8 | 6 | 50.2 t/s \| 24.6 t/s | 73.4 t/s \| 24.1 t/s | 71.8 t/s \| 33.0 t/s |
| DFlash ROCmFP4 | 15 | 50.2 t/s \| 24.6 t/s | 74.2 t/s \| 18.5 t/s | 72.5 t/s \| 30.7 t/s |
| DFlash ROCmFP8 | 15 | 50.4 t/s \| 25.2 t/s | 73.5 t/s \| 19.2 t/s | 72.1 t/s \| 34.6 t/s |

This is a small local throughput benchmark, not a universal performance claim.
Acceptance depends strongly on prompt and generation content. Six draft tokens
was the best tested practical default on this host; tune it for your workload.

Additional verification:

- 731 tensors and `muse-glimmer` architecture in every text GGUF
- 809 tensors and 50 vision blocks in the projector
- ROCmFP4 kernel copy/conversion tests: 34/34 passed on Vulkan
- `test-quantize-fns` and architecture tests passed
- SHA-256 hashes supplied in `SHA256SUMS`

## DFlash, not MTP

These new companion files are converted from Meta's official
[`Muse-Glimmer-30B-assistant`](https://huggingface.co/meta-models/Muse-Glimmer-30B-assistant)
checkpoint. It is a five-layer `MuseGlimmerAssistantModel` using DFlash block
diffusion with a trained block size of 16. Run it with
`--spec-type draft-dflash`; it is not an MTP checkpoint and should not be run
with `draft-mtp`.
