# Models overview

> Browse Elaris's curated catalog of image, video, and audio AI models — from Flux and Veo to ElevenLabs TTS — all priced by the same ~$0.008-per-credit formula.

Elaris routes every generation through a curated model catalog spanning image, video, and audio. Credits scale with model tier, resolution, duration, and quality — all anchored to the same formula: **1 credit ≈ \$0.008**.

## Which model should I use?

Use **`auto`** on image generation when you want Elaris's router to select a strong default. For fine-grained control, pick a specific model from the catalog pages below.

## How do credit costs scale?

| Factor          | Effect on credit cost                          |
| --------------- | ---------------------------------------------- |
| Model tier      | Premium models cost more per generation        |
| Resolution      | 2K / 4K outputs multiply the base image cost   |
| Duration        | Video costs scale linearly with output seconds |
| Quality setting | Higher quality = higher token / compute cost   |

<Tip>
  Studio always shows the estimated credit cost before you confirm a generation. You can switch models or adjust settings to fit your budget without losing your prompt or inputs.
