Choosing a model

Sprello brings many models onto one canvas, so you can match each generation to the result you want—and compare them side by side without switching tools. You pick a model in each generator’s model selector, and you can change it and run again at any time.

​

How to choose

Three things usually decide it:

• Control — do you need to hold exact product detail and brand standards, or are you exploring looks?
• Speed — fast models are great for exploring directions; slower, higher-fidelity models for finals.
• Cost — models consume different amounts of credits. Heavier models and larger sizes cost more.

A good habit: explore with a fast model, then re-run your favorite direction on a higher-fidelity one for the final.

Image models

The number of reference images a model accepts varies—from none for text-only models to many for the larger ones. Sprello shows the limit as you connect references.

​

Video models

Capabilities vary by model—as you set up a generator, Sprello shows what’s available:

• End frame — give a closing image as well as a starting one, and the model interpolates between them.
• Native audio — the model generates sound along with the video.
• 4K — higher output resolution, on the models that support it.
• Reference video — drive a generation with reference clips, not just images.

Staying on brand

When product accuracy matters—hardware, labels, fabric, color—favor higher-fidelity models and connect clear reference images. For consistent results across a set, lock your references and prompt, then generate variations at scale.
