# Nyx Fast

### Model Overview

**Nyx Fast** is a performance-optimized variant of Nyx designed for faster denoising with reduced computational cost. It provides effective noise reduction for workflows where speed and turnaround time are prioritized.

Nyx Fast is well suited for previews, batch processing, and time-sensitive workflows where clean results are needed quickly.

### Key Capabilities

* Faster denoising optimized for speed and efficiency
* Effective noise reduction for high-volume workflows
* Ideal for rapid turnaround and preview processing
