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 the Auto setting, and it’s what we recommend: it gives you the best balance of quality and speed.

If you want to compare results between models or test a specific one, click the Auto / model name button in the bottom-left of the prompt box and pick a model from the list.

Each model brings a slightly different “eye” to your ideas. You don’t have to learn them all, just know they’re there when you want to explore.
