# Nyx High Fidelity

### Model Overview

**Nyx High Fidelity** is a denoise-only model designed to remove grain and noise from high resolution sources while preserving the original image exactly as captured. It performs no sharpening, enhancement, or creative modification, making it ideal for workflows where source fidelity must remain untouched.

Nyx High Fidelity supports advanced finishing pipelines by generating noise passes for external compositing, allowing teams to reintroduce grain or manage noise downstream with full control.

### Key Capabilities

* Maximum detail preservation during noise reduction
* Supports noise pass export for advanced compositing workflows
* Ideal for high-end post-production and finishing pipelines

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.topazlabs.com/video-models/denoise/nyx-high-fidelity.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
