# UniAR Demo

Unified Multimodal Autoregressive Modeling with Shared Context-Visual Tokenizer.

This Space demonstrates **UniAR** (ShareLab-SII/UniAR-RL), a single Transformer
that handles both:

- **Image Understanding** — visual question answering about an input image
- **Image Generation** — text-to-image synthesis via autoregressive visual token prediction

The model uses a shared discrete visual tokenizer (Binary Spherical Quantization)
as the bridge between understanding and generation, enabling a shared context
where the model can directly interpret its own generated visual tokens.
