# Wonder 3.5 — New!

### Model Overview

**Wonder 3.5** is an updated generative upscaling model designed to deliver higher levels of detail, precision, and natural realism across a wide range of image types. It supports both high-quality inputs and heavily degraded or compressed images, with selectable Low, Medium, and High enhancement levels for greater control across varying input conditions.

Building on Wonder 3, Wonder 3.5 produces finer detail with fewer repetitive patterns and improved handling of visual noise. It also delivers greater precision when enhancing structured graphics such as tables and charts, while maintaining strong performance across portraits, landscapes, wildlife, and complex textures.

### Key Capabilities

* Higher-quality results with increased detail and improved realism.
* Transformative enhancement for low-resolution and compressed photos, with improved detail and text clarity.
* Fewer repetitive patterns and improved handling of visual noise.
* Greater precision for tables, charts, and other structured graphics.
* Low, Medium, and High enhancement controls for a range of input conditions.

## 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/wonder/wonder-3.5-new.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.
