MANZANO: A Simple and Scalable Unified Multimodal Model with a Hybrid Vision Tokenizer

Summary

The article presents MANZANO, a unified multimodal model that integrates a hybrid vision tokenizer to enhance the understanding and generation of visual content. By employing a single shared vision encoder and lightweight adapters, MANZANO effectively produces continuous embeddings for image-to-text tasks and discrete tokens for text-to-image generation. This architecture allows for scalable joint learning, achieving state-of-the-art performance among unified models while maintaining competitiveness with specialized models, particularly in text-rich evaluations. The design choices, including the hybrid tokenizer and a unified training recipe, are validated through empirical studies demonstrating minimal task conflicts and consistent performance gains with increased model size.
