🚀 Janus-Pro

Janus-Pro is a novel autoregressive framework that unifies multimodal understanding and generation, offering high flexibility and effectiveness.

🚀 Quick Start

Please refer to Github Repository

✨ Features

• Janus-Pro is a novel autoregressive framework that unifies multimodal understanding and generation.
• It decouples visual encoding into separate pathways while using a single, unified transformer architecture, alleviating the conflict between the visual encoder’s roles in understanding and generation and enhancing flexibility.
• It surpasses previous unified models and matches or exceeds the performance of task - specific models.

Model Summary

Janus-Pro is a unified understanding and generation MLLM, which decouples visual encoding for multimodal understanding and generation. It is constructed based on the DeepSeek-LLM-1.5b-base/DeepSeek-LLM-7b-base.

For multimodal understanding, it uses the SigLIP-L as the vision encoder, which supports 384 x 384 image input. For image generation, Janus-Pro uses the tokenizer from here with a downsample rate of 16.
