MossImage Studio

MossImage Studio is a hosted way to use MOSS-Image, an open-source image model from OpenMOSS. The model's selling point is lettering. MOSS-Image is built to render readable Chinese and English inside the image, and it accepts structured JSON describing where elements go as well as a plain prompt. The studio offers two checkpoints, an SFT version tuned for text-led generation and the Base foundation model.

Around the generator there's a gallery of prompts, presets, a usage guide and downloadable ComfyUI workflows. That last part is useful if you like the results and want to run the open model on your own hardware later.

New users get three starter images after verifying an email, with no card required. One image uses one credit, and technical failures are refunded. Paid options are a one-time pack of 30 non-expiring credits for $9.99, a monthly plan at $14.99 for 80 images that can roll over to 160, and an annual plan at $119 for 800. Downloads carry no watermark.

The studio is operated by Moxion Labs LLC and states that it isn't affiliated with OpenMOSS or fal.ai, the service that hosts generation. The privacy policy, updated October 31, 2026, says prompts, dimensions, seeds and settings are sent to fal.ai. For signed-in accounts, finished images are copied to private Cloudflare R2 storage with their prompts and stay there until you delete them or ask for account deletion. It asks you not to put confidential or sensitive personal details in prompts.
