Jinbin Bai

I received B.S. in CS Degree from Nanjing University and high school diploma from the Affiliated High School of Shanxi University. After that, I studied at CS Dept. of National University of Singapore and founded MeissonFlow Research for developing masking paradigm.

I am trying to find ways to build interactive models and algorithms for content creation. I want to build the world with visual prior, though i sadly agree that the language prior dominates current unified models. I love imagination, I love Astronomy. So I made an analogy in the figure below.

Research

Universal gravity pulls matter into wells. Gradient descent pulls models into minima. Optimization landscapes are just the gravity wells of learning. Some minima (like Mercury) are just... hard to reach.

From Masks to Worlds: A Hitchhiker’s Guide to World Models
Jinbin Bai, Yu Lei, Hecong Wu, Yuchen Zhu, Shufan Li, Yi Xin, Xiangtai Li, Molei Tao, Aditya Grover, Ming-Hsuan Yang
Technical Report 2025
[Paper] [GitHub]
A Hitchhiker’s guide for those who want to build worlds. We follow one clear road: from early masked models, to unified architectures that share a single paradigm, then to interactive generative models, and finally to memory-augmented systems that sustain consistent worlds over time.

DiMOO


Lumina-DiMOO: An Omni Diffusion Large Language Model for Multi-Modal Generation and Understanding
Alpha VLLM Team
Technical Report 2025
[Paper] [Model] [Code]
Lumina-DiMOO is a unified discrete diffusion model that can not only generate high-resolution images, but support multimodal capabilities including text-to-image, image-to-image, and image understanding.

Muddit


Muddit: Liberating Generation Beyond Text-to-Image with a Unified Discrete Diffusion Model
MeissonFlow Research
Technical Report 2025
[Paper] [Model] [Code]
Muddit (offical Meissonic II) is a unified discrete diffusion model that can not only generate high-resolution images, but support multimodal capabilities including text-to-image, image-to-text, and VQA. We verified one unified model can be trained from visual prior learned by Meissonic!

Meissonic


Meissonic: Revitalizing Masked Generative Transformers for Efficient High-Resolution Text-to-Image Synthesis
MeissonFlow Research
ICLR 2025
[Paper] [Model] [Code] [Demo] [Discord_Discussion] [Toturial_EN] [Toturial_JA] [Media_Report_CN]
Meissonic is a text-to-image discrete diffusion model that can generate high-resolution images. It is designed to run on consumer graphics cards. The left figure is generated by Meissonic.

Miscellaneous
  • I am a huge fan of Cities: Skylines and I love designing and simulating cities. I can't wait for the release of Cities: Skylines II on Oct 24th, 2023! And, I've attended World Cities Summit (WCS) 2024 Conference!
  • My favorite movies in recent years is Free Guy, and I dream of designing a game like this.
  • In my leisure moments, I delight in playing the piano surrounded by abundant greenery, finding peace and emotional comfort in the solitude.
  • I enjoy traveling and have visited 13 countries, guess where I have been?
  • I like swimming, diving, surfing, beach under the sunshine.
