Muse-Glimmer-30B ROCmFPX GGUF

ROCmFP4 and ROCmFP8 builds of 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. 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 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 base commit 00d54526e24e3aba4c76474e3147cbf9c7cc034c
upstream llama.cpp Muse support 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 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:

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

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)

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

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 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.
