CrowMuse-Glimmer-30B-Heretic — Reproducible Refusal-Reduced GGUF with Vision + DFlash

CrowMuse-Glimmer-30B-Heretic is a GGUF release based on meta-models/Muse-Glimmer-30B. It combines QLoRA fine-tuning with a final-stage Heretic pass applied after all fine-tuning stages were merged.

Highlights

  • Text and image input
  • Q3_K_M, Q4_K_M, Q5_K_M, Q6_K, and Q8_0 quantizations
  • Fresh importance matrix computed from the final checkpoint
  • F16 vision projector included
  • Optional DFlash speculative-decoding model included
  • Converted and tested with llama.cpp b10360

This is a community model and is not an official Meta, Heretic, or llama.cpp release. Refusal reduction does not guarantee correctness or safety. Review the included usage policy before deployment.

mmproj-F16.gguf 3.58 GiB Vision projector for image input
dflash-kquant.gguf 1.52 GiB Optional DFlash drafter

Q4_K_M is the recommended starting point. Download mmproj-F16.gguf only when image input is needed, and dflash-kquant.gguf only when using DFlash.

Requirements

Use llama.cpp b10353 or newer. This release was built and smoke-tested with b10360 (48d22e295e2b86b47366c16390794f3e05ba970a).

Usage

Text

llama-cli \
  -m gguf/CrowMuse-Glimmer-30B-Heretic-Q4_K_M.gguf \
  -ngl all -c 32768 --jinja \
  --temp 1.0 --top-p 0.95 --top-k 64

Image input

llama-mtmd-cli \
  -m gguf/CrowMuse-Glimmer-30B-Heretic-Q4_K_M.gguf \
  --mmproj gguf/mmproj-F16.gguf \
  --image photo.png \
  -p "Describe this image accurately." \
  -ngl all -c 32768 --jinja

Optional DFlash

llama-cli \
  -m gguf/CrowMuse-Glimmer-30B-Heretic-Q4_K_M.gguf \
  -md gguf/dflash-kquant.gguf \
  --spec-type draft-dflash --spec-draft-n-max 15 \
  -ngl all -ngld all -c 32768 --jinja

DFlash performance depends on hardware, backend, prompt length, and draft-token acceptance rate. The main GGUF works without the DFlash file.

Evaluation

The published Q4_K_M file was evaluated with llama.cpp b10360 using seed 20260812.

Task Correct / total Accuracy
ARC Challenge 197 / 299 65.89%
ARC Easy 500 / 570 87.72%
BoolQ 2,879 / 3,270 88.04%
OpenBookQA 245 / 500 49.00%
PIQA 1,537 / 1,838 83.62%
MMLU validation 792 / 1,548 51.16%
HellaSwag 8,332 / 10,042 82.97%
WinoGrande 1,002 / 1,267 79.08%

The final Heretic strength was selected as a quality/refusal-reduction balance. In the 96-token sweep, strict refusal-marker matches decreased from 63/100 to 47/100, and all 100/100 responses remained nonempty. Results vary with prompt format and evaluation length, so these figures should be treated as limited behavioral indicators rather than universal guarantees.

Across the six capability tasks with directly comparable pre-final results, the unweighted mean changed by -0.16 percentage points; the largest individual decline was -0.67 points. Text, image, and DFlash smoke tests all completed successfully.

Full aggregate results and limitations are available in evaluation/results.json.
