inclusionAI/ZwZ-7B
ZwZ-7B is a 7 billion parameter fine-grained multimodal perception model developed by inclusionAI, built upon Qwen2.5-VL-7B. It is trained using Region-to-Image Distillation (R2I) and reinforcement learning to enable superior fine-grained visual understanding in a single forward pass, eliminating the need for inference-time zooming or tool calling. This model excels at detailed visual analysis, achieving leading performance on fine-grained perception benchmarks among open-source Qwen2.5-VL-7B-based models.

ZwZ-7B: Fine-Grained Multimodal Perception
ZwZ-7B is a 7 billion parameter multimodal model developed by inclusionAI, specifically designed for fine-grained visual understanding. Built on the Qwen2.5-VL-7B architecture, this model introduces a novel approach called Region-to-Image Distillation (R2I) combined with reinforcement learning.
Key Capabilities
- Single-Pass Fine-Grained Perception: Unlike traditional methods that require inference-time zooming or tool calls, ZwZ-7B processes detailed visual information in a single forward pass, significantly reducing latency.
- Enhanced Visual Detail: Achieves superior performance on benchmarks requiring fine-grained visual analysis, such as counting, OCR, and identifying specific attributes (color, structural, material).
- Efficient Training Methodology: Leverages a unique training process that distills region-grounded supervision from powerful teacher models (like Qwen3-VL-235B and GLM-4.5V) back to full images with explicit bounding-box overlays.
- Strong Benchmark Performance: Demonstrates leading results among open-source Qwen2.5-VL-7B-based models on fine-grained perception tasks, including the challenging ZoomBench dataset.
Good For
- Applications requiring high-accuracy, detailed visual analysis without the overhead of multiple inference steps.
- Tasks such as object counting, optical character recognition (OCR), and precise attribute identification within images.
- Developers seeking an efficient and performant open-source model for fine-grained multimodal perception.
