# VIEW2SPACE: Studying Multi-View Visual Reasoning from Sparse Observations
`view2space_4b` is an ECCV 2026 VIEW2SPACE model built on top of
[Qwen/Qwen3-VL-4B-Instruct](https://huggingface.co/Qwen/Qwen3-VL-4B-Instruct).
It is designed for grounded multi-view visual reasoning from sparse
observations.

## Overview
VIEW2SPACE studies how vision-language models reason across sparse and
heterogeneous viewpoints. Instead of solving a task from a single image, the
model must integrate partial observations from multiple views to form a more
complete spatial understanding.
This checkpoint is the `Qwen3-VL-4B` VIEW2SPACE model release and is intended
for multi-view visual reasoning under sparse observations.
## Model Summary
- Model name: `view2space_4b`
- Base model: `Qwen/Qwen3-VL-4B-Instruct`
- Architecture: `Qwen3VLForConditionalGeneration`
- Project: VIEW2SPACE
- Use case: multi-view visual reasoning from sparse observations
- Venue: ECCV 2026
## Highlights
- Built for grounded multi-view reasoning rather than single-image prediction.
- Targets sparse observations and heterogeneous viewpoints.
- Released together with the public VIEW2SPACE testing set and evaluation code.
