What’s Model Training
Training AI models, also known as fine-tuning, involves customizing a base model to generate images that closely reflect the characteristics of the training set, whether it's a specific style, subject, or other visual elements.
Scenario offers a streamlined UI for training custom AI models: all on a single page, in just a few clicks. You can simply select and import your training images via drag & drop, copy-pasting, or uploading. Training sets can include 5 to 100 images (depending on your plan), but most models perform well with 10-20 images.
Training Images Requirements
All training images must be at least 1024x1024. If you upload a non-square image, you can either fit it within a square (default) or crop it to focus on a portion of the image directly within Scenario.
Below is an example showing two options (“Fit within Square” vs. “Cropped to Square”). Both work but the resulting models will yield different results. If you plan to generate a lot of landscape- or portrait-oriented images, it's useful to include similarly formatted images in your training set:
Captions
Click “Upload Images“. Every image in the training set will be automatically captioned with a short description (caption) being added under each image. You can keep, review, or edit captions as needed by clicking on them (more on captioning).
In the left panel, choose a base model, adjust Advanced Training Settings if necessary (more info here), and click Start Training.
Training Time
The process typically takes 30 minutes to one hour, depending on the number of images. Once training is complete, you'll receive an email notification (or in-app notification with a red dot in the top bar), and the newly trained model will appear in the “Your Models“ gallery.
Now, let’s focus on understanding different model types, improving results, and managing hundreds of custom-trained models, at scale:
