Guide to Image Generation Models

Not all AI models create the same way. Here’s a quick overview of every image model in getimg.ai and which aspect ratios they support.

What Are Image Generation Models?

Models are the creative “brains” behind image generation. Each one has its own strengths: some give more photorealistic results, some more stylized.

By default, getimg.ai automatically picks the model that best fits what you want to create. That’s Auto Mode, and it’s what we recommend: it gives you the best balance of quality and speed.

But if you want to compare results between models or test specific ones, you can switch to Custom Generation Parameters and select a model manually.
