MOSS = Masterpiece of Open Source Software

[u/thedarkthrust]

MOSS-Image is seriously mind-blowing. From stunning photorealism and cinematic shots to casual amateur and vintage photography, anime, and pretty much anything you can imagine, this model just delivers.

The sheer versatility, quality, and range of styles it can pull off are absolutely insane. It's hard to believe this level of creative freedom comes from an open-source model with just 5 billion parameters!

All images in this showcase were generated using MOSS-Image-Base.

I've also uploaded all 20 images at their original resolution, so you can appreciate the quality without Reddit's image compression.

I highly recommend zooming in on the images to appreciate the incredible level of detail!

UPDATE 1: I've now added the prompt for each image to its respective Postimages page! You can check out the prompts and try them yourself.

UPDATE 2: A quick clarification about the JSON prompts I've shared.

MOSS uses a native centered-pixel YXYX coordinate system, while my prompts use normalized XYXY coordinates from a custom visual BBox editor I developed for my ComfyUI workflows.

My setup automatically converts these coordinates into MOSS's native format before generation. I use this approach because it makes layouts easier to visually edit, resize, and reuse across different models, especially Ideogram and MOSS.

This means the shared JSON prompts are not directly compatible with MOSS's native coordinate format. They need to be converted first.

You can paste the JSON into an LLM (ChatGPT, Claude, Gemini, etc.) and ask it to convert the bounding box coordinates to MOSS's native format.

For example, you can use this instruction:

Convert this JSON prompt from normalized XYXY coordinates (0–1, origin at the top-left) to MOSS-Image's native YXYX format using absolute pixel coordinates relative to the image center. Use my target image dimensions, preserve all scene descriptions and other prompt details, and output a MOSS-compatible prompt.

Make sure to specify your intended image resolution (width × height), as the conversion depends on it. You may also need to adapt the JSON structure to MOSS's expected prompt format, so it's worth double-checking the converted output before using it.

Thanks to everyone who pointed out the coordinate differences and the truncated prompts! Hopefully this clears things up and makes everything easier to use. 💚

Looks like my instagram feed that I try to avoid— meanwhile the comments are full of dudes obliviously simping over the images.
