# Topaz Wonder 3.5

> One-click generative image upscaling with Topaz Wonder 3.5. See parameters, pricing, and API examples.

One-click generative upscaling. Wonder rebuilds clean, realistic detail with no settings to tune.

## Model

```
topaz-labs/wonder-3.5
```

## When to use

* **Your default AI upscale**, for example right after generating an image. `upscale_factor` goes up to 6x.
* Low-to-medium resolution photos and graphics that need more detail, with no tuning.

**Pick something else when:**

* You want to steer what gets rebuilt with a prompt: use [Redefine](/models/image/topaz-labs/redefine).
* The photo is badly damaged or tiny: use [Recover 3](/models/image/topaz-labs/recover-3).
* You want a richer, more artistic result: use [Bloom 2](/models/image/topaz-labs/bloom-2).
* The image is already sharp and you only need it bigger: use [Topaz Image Upscale](/models/image/topaz-labs/image-upscale) (cheaper, no invented detail).

<Note>
  Billed per started block of output megapixels (source size × `upscale_factor`). Maximum output is **256 MP**.
