    AI image generation / fine-tuning (Flux, SDXL)

    Astria is a fine-tuning and image generation platform for developers and creators who need custom visual models: product shots, headshots, virtual try-on, and branded styles. You train on a small image set (Flux LoRA/checkpoint presets) and generate images via API or web UI. It is infrastructure for custom visuals, not a general consumer photo app.
