What it does
Stability AI's hosted demo of Stable Diffusion 3 Medium, a generation that follows prompts closely and renders text inside images comparatively well. Nothing to install and no account. The model is released under a non-commercial licence, so output cannot be used for paid work or monetised content without taking out Stability's separate commercial agreement. Prompts are sent to the host's servers.
Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.
