Ostris announced that its open-source AI Toolkit now supports training Qwen-Image-2.1, including native alpha channel support.

The author tested it on a small t-shirt design dataset: no trigger word or dedicated alpha text was needed—just default sample prompts—and results looked good after only 750 training steps. Native alpha support, he argues, unlocks many new workflows for transparent assets, stickers, and print design.
