Muse Glimmer 30B - W2A16 AutoRound / GPTQ

This repository contains the W2A16 quantized versions of Meta's Muse Glimmer 30B, optimized for extreme memory efficiency during local inference. The model was quantized using Intel AutoRound to 2-bit precision. To preserve the model's multimodal and agentic capabilities, the Vision Encoder was explicitly kept in its original precision (BF16).

Two formats are provided across the repositories:

  • AutoRound Format: Vishva007/Muse-Glimmer-30B-W2A16-AutoRound
  • AutoGPTQ Format: Vishva007/Muse-Glimmer-30B-W2A16-AutoRound-GPTQ

Quantization Details

The quantization was performed with high-accuracy calibration settings tailored for 2-bit compression:

  • Scheme: W2A16 (2-bit weights, 16-bit activations)
  • Group Size: 32 (Lowered to preserve accuracy in 2-bit)
  • Symmetric: True
  • Iterations: 1000
  • Vision Module: Kept unquantized (quant_nontext_module=False) to ensure maximum vision-language alignment.
  • Calibration: 512 samples, sequence length of 2048.

By compressing the language model weights to 2-bit precision, this version vastly reduces VRAM requirements, leaving ample room for the KV cache and the unquantized perception encoder to run smoothly on lower-VRAM consumer GPUs.

Usage with vLLM

For optimal performance, including agentic function calling and reasoning parsing, use the vllm/vllm-openai:muse-glimmer image or the latest vLLM build supporting Muse Glimmer.

Run the following command to serve the model (adjust the model path to the AutoRound or GPTQ repo as needed):

vllm serve Vishva007/Muse-Glimmer-30B-W2A16-AutoRound \
  --served-model-name muse-glimmer \
  --gpu-memory-utilization 0.90 \
  --max-model-len 32768 \
  --max-num-seqs 128 \
  --generation-config auto \
  --enable-auto-tool-choice \
  --tool-call-parser muse_glimmer \
  --reasoning-parser muse_glimmer

Key vLLM Flags Explained

  • --max-model-len 32768: Sets the context window to 32k tokens.
  • --enable-auto-tool-choice: Enables agentic tool selection.
  • --tool-call-parser / --reasoning-parser: Configures the endpoint to natively handle Muse Glimmer's multi-step thinking and function schema outputs.

About the Base Model (Muse Glimmer 30B)

Muse Glimmer is a 30-billion-parameter causal language model with a dedicated perception encoder (~1.8B param ViT-G/14), distilled from Muse Spark by Meta Superintelligence Lab. It is purpose-built for autonomous agentic tasks on consumer hardware.

Key Capabilities:

  • End-to-end Agentic Task Completion: High success rates on DeepSearch QA, MCP-Atlas, 𝛕3-Bench, and SWE-Bench.
  • Multimodal Reasoning: Interprets interleaved text and images (charts, documents, screenshots).
  • Reliable Tool Use & Failure Recovery: Handles complex tool schemas and automatically diagnoses/retries failed calls.
  • Controllable Effort: Supports customizable reasoning strengths (low/medium/high/xhigh) via system prompts.
  • Multilingual: Trained on data from more than 100 languages.
