What are Custom AI Models?
Custom AI models are trained on your images to learn specific styles, people, objects, or scenes. Once trained, you can use these models to generate new images that incorporate what the AI has learned.
Model Types
Samsa offers four types of custom models:
Person Models
Train on photos of a specific person to generate new images featuring them in any scenario, style, or setting.
Style Models
Capture a unique visual style—artistic techniques, color palettes, or aesthetic approaches—to apply to any subject.
Object Models
Teach the AI to recognize and recreate specific products, items, or objects with accurate details.
Scene Models
Train on environments, locations, or backgrounds to generate consistent settings for your images.
How Training Works
Upload training images — one image is enough to start, 2–5 images give the best results
Choose model type based on what you're training
Start training — it takes about 15 seconds
Use your model — open the dropdown below the prompt field, select your model, and it's added to your prompt like a building block
You'll get a notification when training is complete. Once trained, you can reuse your model unlimited times.
Combine multiple models in one generation
In any of the five studios you can combine up to 5 person models, up to 5 object models, and up to 5 scene models in a single generation. Style is single-select — only 1 style model can be active at a time. This makes it easy to picture multiple people together, feature several products in one shot, or layer scene references for richer compositions.
Training is Free
Model training is free and unlimited on all plans. Using your trained models in generation costs the same as regular generation.
Best Practices
Image order matters: If you're not satisfied with results, try reordering your training images
Variety matters: Include different angles, lighting, and contexts
Consistent subject: Ensure all images feature the same subject clearly
High resolution: Better training images lead to better results
Custom Instructions
You can add custom instructions to your models — rules that the AI follows in all generations using that model. This is great for corporate guidelines or brand rules. Learn more in the Managing Your Models article.
