MOSS-Image
What is MOSS-Image?
MOSS-Image is a 5 billion parameter diffusion transformer model designed for high-quality text-to-image generation. It focuses on delivering clear and accurate text rendering within generated images while providing precise control over layout and composition. The model accepts prompts up to 4,000 tokens and supports diverse visual styles, including anime and photorealistic outputs.
The repository provides publicly available code and model weights under an Apache-2.0 license. It includes integration support for ComfyUI, SGLang, and vLLM-Omni, along with a Gradio-based interface for local testing. Training tools like KohakuMossTrainer enable full fine-tuning and adapter training with mixed precision and multi-GPU setups across NVIDIA and Intel hardware.
Community extensions offer additional capabilities such as vertical banding reduction, sampling acceleration, and format conversion for standard diffusion pipelines. The model is also accessible through the MOSI API Platform for cloud-based inference and playground testing.
