</div>Model Summary
ZwZ-2B is a fine-grained multimodal perception model built upon Qwen3-VL-2B. It is trained using Region-to-Image Distillation (R2I) combined with reinforcement learning, enabling superior fine-grained visual understanding in a single forward pass — no inference-time zooming or tool calling required. ZwZ-2B achieves state-of-the-art performance on fine-grained perception benchmarks among open-source models of comparable size.

- ⚡ Single-Pass Efficiency: Achieves fine-grained perception in one forward pass, eliminating inference-time tool-calling overhead
- 🎯 Superior Accuracy: State-of-the-art on perception benchmarks among open-source models
- 📈 Broad Improvements: Enhances not only perception benchmarks but also out-of-distribution generalization on visual reasoning, GUI agent, and AIGC detection
How It Works
Traditional "Thinking-with-Images" methods zoom into regions of interest during inference, incurring high latency from repeated tool calls and visual re-encoding. ZwZ transforms zooming from an inference-time tool into a training-time primitive:
- Zoom in to micro-cropped regions and let strong teacher models (Qwen3-VL-235B, GLM-4.5V) generate high-quality VQA data
- Distill this region-grounded supervision back to the full image with explicit bounding-box overlays
- Reinforce via RL training to enable single-glance fine-grained perception without tool use
Quickstart
Installation
pip install transformers accelerate torch
Inference
from transformers import Qwen3VLForConditionalGeneration, AutoProcessor
# default: Load the model on the available device(s)
model = Qwen3VLForConditionalGeneration.from_pretrained(
"inclusionAI/ZwZ-2B", dtype="auto", device_map="auto"
)
processor = AutoProcessor.from_pretrained("inclusionAI/ZwZ-2B")
messages = [
{
"role": "user",
"content": [
{
"type": "image",
"image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg",
},
{"type": "text", "text": "Describe this image."},
],
}
]
# Preparation for inference
inputs = processor.apply_chat_template(
messages,
tokenize=True,
add_generation_prompt=True,
return_dict=True,
return_tensors="pt"
)
inputs = inputs.to(model.device)
# Inference: Generation of the output
generated_ids = model.generate(**inputs, max_new_tokens=128)
generated_ids_trimmed = [
out_ids[len(in_ids) :] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
]
output_text = processor.batch_decode(
generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
)
print(output_text)
Training Data
ZwZ-2B is trained on inclusionAI/ZwZ-RL-VQA, a 74K-sample Region-to-Image distilled VQA dataset synthesized from diverse image pools (SA-1B, LAION, MetaCLIP, Visual Genome, CC12M, STPLS3D).
