Muse-Glimmer-30B-uncensored2-AutoRound-W4A16-G128

AutoRound W4A16 (4-bit weights / 16-bit activations, group_size=128, symmetric) quantization of electroglyph/Muse-Glimmer-30B-uncensored2.

  • Tool: Intel AutoRound (scheme="W4A16", format="auto_round")
  • Real SignRound tuning on calibration data (not RTN).
  • Calibration: HuggingFaceH4/ultrachat_200k:num=384,nvidia/OpenCodeInstruct:num=128 (nsamples=512, seqlen=2048, iters=1000).

Run with vLLM (native kernel, no --quantization flag)

auto_round W4A16 is in vLLM's Intel Quantization Support (W4A16 weight-only) and is served directly:

pip install vllm
vllm serve electroglyph/Muse-Glimmer-30B-uncensored2-AutoRound-W4A16-G128 --gpu-memory-utilization 0.8 --max-model-len 32768

Python:

from vllm import LLM, SamplingParams
llm = LLM(model="electroglyph/Muse-Glimmer-30B-uncensored2-AutoRound-W4A16-G128")
print(llm.generate(["Hello, my name is"], SamplingParams(temperature=0.6, top_p=0.95))[0].outputs[0].text)

Run with Transformers

pip install -U "transformers>=5.22.2" auto-round  # auto-round registers the auto_round format
from transformers import AutoProcessor, AutoModelForImageTextToText
processor = AutoProcessor.from_pretrained("electroglyph/Muse-Glimmer-30B-uncensored2-AutoRound-W4A16-G128")
model = AutoModelForImageTextToText.from_pretrained("electroglyph/Muse-Glimmer-30B-uncensored2-AutoRound-W4A16-G128", device_map="auto", torch_dtype="auto")

Best practice sampling (per the source model card): temperature=1.0, top_p=0.95, top_k=64. Reasoning strength is set in the system prompt (Reasoning strength: <low|medium|high|xhigh>); use high/xhigh for coding and agentic tasks.
