Ostris AI Toolkit adds training support for OpenMOSS's MOSS-Image-SFT model

ostrisai · x · 2026-10-16

The popular open-source diffusion training suite Ostris AI Toolkit now supports OpenMOSS's MOSS-Image-SFT text-to-image model. The SFT model is fine-tuned from MOSS-Image-Base, shares the same architecture and pipeline, and supports natural-language prompts, tag sequences, and JSON layouts for text placement and object arrangement, released under Apache-2.0 on Hugging Face.

A 1,290-line commit adding MOSS Image support has landed in the toolkit, alongside existing FLUX.2-family support, letting users fine-tune MOSS-Image-SFT directly with ai-toolkit.
