MOSS-Image Online is an independent web generator for OpenMOSS’s open-weight MOSS-Image model, a 5B diffusion transformer released in October 2026 under Apache-2.0. Its strength is rendering real Chinese and English text inside images — posters, menus, signs, book covers and whiteboards — with prompts up to 4,096 tokens and optional JSON layout boxes that place each headline and object exactly where you want it. Describe the finished picture and quote the exact words to render, then download a full-size PNG. The site is upfront that it is not affiliated with OpenMOSS and links to the official project, and it documents the model with a spec sheet, benchmark comparisons and guides for ComfyUI, Diffusers and the official MOSI API. Signing up gives three free standard images; after that, generation uses credits from one-time packs starting at $4.99, and you can also run the open weights yourself on your own hardware or free Hugging Face quota. It suits designers and marketers who need posters and packaging with accurate bilingual lettering without a GPU or an API key.
