Frequently Asked Questions
What is fine-tuning?
Fine-tuning is the process of adapting pre-trained generative AI models like Flux or Stable Diffusion to create personalized results for specific subjects or styles. Astria's fine-tuning API allows generating studio-quality images of a subject, including professional headshots, cartoons, and avatars, by training on just 4-16 reference images.
How many training images do I need?
Astria recommends uploading 8-16 images of the subject, though the system accepts between 4-30 images. For best results, include 10 portrait shots from shoulders up, 4 medium shots from the waist up, and 2-4 full-body shots. Images should be clear, well-lit, from different days with varied clothing, backgrounds, and lighting.
How long does it take to generate images?
The fine-tuning process typically takes about 8 minutes. Once your custom model is trained, generating individual images takes seconds. The auto-scaling infrastructure ensures no queue times, even during peak usage periods.
Can I use Astria for commercial purposes?
Yes, customers may use Astria's playground GUI and API services without any additional licensing requirements. Generated images can be used for commercial purposes including marketing materials, product listings, and business applications.
What models does Astria support?
Astria supports Flux, Stable Diffusion 1.5 (SD1.5), and Stable Diffusion XL (SDXL) models. The platform offers different fine-tuning approaches including Checkpoint and LoRAs, along with FaceID adapter alternatives for faster processing with lower resemblance requirements.
Is there a refund policy?
Due to the computational costs of GPU processing, Astria cannot refund orders once processing begins. However, the technology works reliably when users follow the training image guidelines. Quality results depend largely on providing clear, diverse, and well-lit training images.
