# Rhea

### Model Overview

**Rhea** is a high fidelity enhancement model designed for 4× upscaling of organic textures and fine detail, delivering clean, controlled sharpness while preserving natural structure.

Rhea blends the general enhancement strengths of Proteus with the facial recovery capabilities of Iris to recover fine detail and faces from lower resolution sources such as 480p footage. It operates natively at a 4× scale and is best suited for workflows where maximum detail preservation is prioritized over render speed.

### Key Capabilities

* Optimized for high quality 4× upscaling of organic textures and fine detail
* Preserves faces, text, and small structures with natural looking sharpness
* Best suited for clean or lower resolution sources where fidelity is prioritized over speed

# 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/proteus/rhea.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.
