# High Fidelity 2

### Model Overview

**High Fidelity 2** is a precision upscaling model designed for images that are already high resolution and well captured. It focuses on enlarging images while preserving fine detail, natural texture, and structural accuracy, avoiding aggressive reconstruction or over-sharpening.

### Key Capabilities

* High-fidelity upscaling for already high-resolution sources
* Preserves fine detail and original texture during enlargement

### Getting Started

**Endpoint**

* <https://api.topazlabs.com/image/v1/enhance/async>
  * `model` — `"High Fidelity V2"`

<details>

<summary><strong>Endpoint-Specific Parameters</strong></summary>

* `face_enhancement` — boolean
  * Leverages our face recovery model to enhance faces.
* `face_enhancement_strength` — decimal between 0 and 1 *(required if `face_enhancement=true`)*
  * Sets the strength of the face recovery.
* `face_enhancement_creativity` — decimal between 0 and 1 *(required if `face_enhancement=true`)*
  * Choose realistic or creative face recovery.
* `subject_detection` — `"foreground"`, `"background"`, or `"all"`
  * Choose where enhancements are applied.
* `sharpen` — decimal between 0 and 1
  * Slightly sharpens the image.
* `denoise` — decimal between 0 and 1
  * Reduces noise in the image.
* `fix_compression` — decimal between 0 and 1
  * Reduces compression artifacts to improve details.
* `strength` — decimal between 0.01 and 1
  * Controls model strength. Too high of a result can make results look unrealistic.

These parameters should be appended as key-value fields in the form-data request bodies (i.e. alongside the `model`, `output_height`, and `face_enhancement` etc. fields). Any parameters not explicitly provided are **automatically** configured by our auto-parameter model. Extra parameters provided that are not supported are ignored.

**Model-Specific Parameters**

# 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/image-models/gigapixel/high-fidelity-2.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.
