OpenMOSS releases MOSS-Image: 5B open text-to-image model with JSON layout control

AdinaYakup · x · 2026-10-17

The OpenMOSS team open-sourced MOSS-Image-Base, a 5B text-to-image model under Apache 2.0. It supports natural-language prompts, tag sequences, and JSON layout control for text placement and object arrangement, with up to 4K token prompts. The model card demos fine Chinese handwritten text rendering; Base and SFT versions are provided (SFT gives clearer text grouping and tidier whiteboard layouts). Available on Hugging Face via a custom Diffusers pipeline, with ComfyUI support.
