Janus-Pro: Unified Multimodal Understanding and Generation with Data and Model Scaling

Janus-Pro is an advanced version of the previous Janus model, incorporating optimized training strategies, expanded training data, and a larger model size.

It achieves significant advancements in multimodal understanding and text-to-image instruction-following capabilities, while enhancing the stability of text-to-image generation.

The model uses a decoupled visual encoding architecture, separate pathways for visual understanding and generation, and leverages synthetic data to improve performance.
