Astria

The AI tool that lets you create custom, unique images and videos. Astria specializes in fine-tuning AI image models to generate personalized, consistent images like custom headshots, avatars, product visuals, or artistic renders. It supports Flux, Stable Diffusion XL (SDXL), and Stable Diffusion 1.5 (SD1.5), with Flux often providing the highest current quality. The web interface is straightforward for uploading images and training, though API use benefits from developer knowledge. Typically a few hours, depending on model and dataset size, with no long queues reported. Licensing covers commercial use for open models, and many users build services or products around it. Unlimited free tier is highlighted, but you can buy credits to start small and test with gallery packs.
