Qwen2.5-VL-3B-Instruct-W4A16-nova_floor

Qwen2.5-VL-3B-Instruct-W4A16-nova_floor

Quantized with the NOVA quantization pipeline on 2026-04-27. Base model: Qwen/Qwen2.5-VL-3B-Instruct

Quantization details

Benchmark results

TTFT and TPOT measured with BaseStreamer injection (prompt-skip corrected).

Registry notes

• Use llm-compressor==0.5.1 + transformers==4.51.3 for quantization.
• Use vLLM>=0.7.2 for inference — Marlin kernels active on Ampere.
• Projector (model.visual.merger) kept at FP32 — matched by visual.* regex.
• OCR and bbox grounding regress 5x faster than MMMU under aggressive quant.
• Keep merger at FP32, not BF16, for best bbox coordinate precision.
• W8A8 requires A100 for calibration — activation statistics need >24GB VRAM.

Usage

from transformers import Qwen2_5_VLForConditionalGeneration, AutoProcessor
import torch

model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
    "Mohaaxa/Qwen2.5-VL-3B-Instruct-W4A16-nova_floor",
    torch_dtype=torch.bfloat16,
    device_map="auto",
)
processor = AutoProcessor.from_pretrained("Mohaaxa/Qwen2.5-VL-3B-Instruct-W4A16-nova_floor")
