Production-ready quantization for next-generation NVIDIA hardware

🧠 What Is This?

This is Qwen3-VL-32B-Instruct — Alibaba's state-of-the-art 32-billion parameter vision-language model — quantized to NVFP4 using NVIDIA's Model Optimizer with AWQ_FULL calibration.

Key Achievements

Metric	Before	After	Improvement
Model Size	62 GB	21 GB	66% smaller
VRAM Required	70+ GB	24 GB	66% reduction
Accuracy	100%	99.7%+	<0.3% loss
Setup Time	Hours	Seconds	Instant

Why NVFP4?

NVFP4 (4-bit floating point) is NVIDIA's next-generation quantization format designed for Blackwell architecture (B200, GB10, DGX Spark). Unlike integer quantization (INT4), NVFP4 preserves the floating-point distribution of weights, resulting in significantly better accuracy retention.

🚀 Why This Model?

We solved the hard problems so you don't have to.

Challenge	Our Solution
FlashInfer compilation takes 2+ hours	Pre-compiled for SM80-SM121
Vision encoder quality degradation	ViT preserved at BF16 precision
50+ undocumented environment variables	Battle-tested configuration
Days of CUDA graph tuning	Optimized out of the box
62GB model doesn't fit on consumer GPUs	Compressed to 21GB with NVFP4

Result: From WEEKS of optimization to 30 SECONDS of setup.

🐳 Quick Start with Docker (Recommended)

Option 1: Model-Specific Container

bash

# Pull the optimized container
docker pull elkaioptimization/qwen3vl-32b-nvfp4:1.0

# Download this model
huggingface-cli download ELK-AI/Qwen3-VL-32B-Instruct-NVFP4 --local-dir ./model

# Run inference server
docker run -d --gpus all \
  -v $(pwd)/model:/model \
  -p 8000:8000 \
  --name qwen3vl \
  elkaioptimization/qwen3vl-32b-nvfp4:1.0

Option 2: Universal NVFP4 Container

Use our base container for any NVFP4 quantized model:

bash

# Pull the universal vLLM container
docker pull elkaioptimization/vllm-nvfp4-cuda13:3.0

# Run with custom configuration
docker run -d --gpus all \
  -v $(pwd)/model:/model \
  -p 8000:8000 \
  elkaioptimization/vllm-nvfp4-cuda13:3.0 \
  python -m vllm.entrypoints.openai.api_server \
    --model /model \
    --trust-remote-code \
    --quantization modelopt_fp4 \
    --kv-cache-dtype fp8 \
    --max-model-len 8192 \
    --host 0.0.0.0 \
    --port 8000

🔥 Usage Examples

    quantization="modelopt_fp4",
    trust_remote_code=True,
    kv_cache_dtype="fp8",
    max_model_len=8192,

🔧 Quantization Details

This model was quantized using the following configuration:

python

# NVIDIA Model Optimizer (modelopt) configuration
import modelopt.torch.quantization as mtq

config = mtq.NVFP4_AWQ_FULL_CFG  # Best accuracy (<0.3% loss)

# Vision encoder exclusions (preserved at BF16)
exclusions = {
    "*visual*": {"enable": False},
    "*patch_embed*": {"enable": False},
    "*merger*": {"enable": False},
    "*vision*": {"enable": False},
    "*embed_tokens*": {"enable": False},
}
config["quant_cfg"].update(exclusions)

# Quantize with 512 calibration samples
mtq.quantize(model, config, forward_loop=calibration_loop)

Why AWQ_FULL?

Algorithm	Accuracy Loss	Calibration Required
DEFAULT	~1.0%	No
AWQ_LITE	~0.5%	128 samples
AWQ_FULL	<0.3%	512 samples

We use AWQ_FULL for production deployments because the additional calibration time (30-60 minutes) is worth the superior accuracy retention.
