Muse-Glimmer-30B ROCmFPX build

Pinned inputs

  • Hugging Face model: meta-models/Muse-Glimmer-30B
  • Model revision: f84ecc3a0ea984a4c04542a84269e3d065350a6e
  • Hugging Face drafter: meta-models/Muse-Glimmer-30B-assistant
  • Drafter revision: 2c86316d689027b91123638739743fef1d425233
  • ROCmFPX base: 00d54526e24e3aba4c76474e3147cbf9c7cc034c
  • Upstream Muse support: 62bf73d25c53b8161f8a22894d4f90c4aebbd7d0
  • Upstream converter worktree: d2f83055dca6dd009d8a52bdff792fbb286f4444
  • Converter environment: Python venv with transformers==5.15.0
  • Target GPU: AMD Strix Halo, gfx1151

The toolchain directory is an uncommitted worktree based on ROCmFPX with the upstream Muse support adapted to the older ROCmFPX APIs. It does not alter the canonical /home/vmlinux/models/llama.cpp checkout or build.

Deliverables

Artifact label Quantizer preset Intent
ROCmFP4 Q4_0_ROCMFP4_STRIX Strix Halo speed/quality recipe; dual-scale FP4 attention K/V and Q6_K token embeddings
ROCmFP8 Q8_0_ROCMFPX High-fidelity 8.25-bpw reference layout
ROCmFP4-Q6-QUALITY Q4_0_ROCMFP4_COHERENT Dual-scale FP4 body with Q6_K token embeddings for the coherence-biased quality build
DFlash ROCmFP4 Q4_0_ROCMFP4_STRIX Small, speed-oriented official DFlash companion; recommended on Strix Halo
DFlash ROCmFP8 Q8_0_ROCMFPX Higher-precision DFlash reference for acceptance and hardware tuning

The two FP4 builds use a 500-chunk importance matrix generated from the local narrative-general-imatrix-sample.txt corpus. This supplies varied prose, reasoning, and general-language activations; the coherence preset itself provides the agent/tool-oriented tensor routing. The FP8 reference does not need an importance matrix because its preset does not consume importance weights.

The DFlash drafters do not use the main-model iMatrix. They are quantized from the official assistant checkpoint, and the FP4 conversion keeps the feature fusion fc.weight at Q8_0 as a precision floor.
