# Bloom 2 — New & Improved!

### Model Overview <a href="#model-overview" id="model-overview"></a>

**Bloom 2** is a creative generative AI upscaling model designed for native GenAI images, including AI-generated artwork, illustrations, and CG renders. It enhances image quality while introducing new detail, texture, and visual elements, with the ability to subtly refine the source or substantially reimagine it.

A Creativity control from 1–10 determines how strongly Bloom 2 transforms the source, from restrained enhancement to more pronounced reinterpretation and newly generated detail. Bloom 2 also includes optional Face Recovery to improve facial and skin detail and reduce the plastic look common in AI-generated images, plus Color Preservation to maintain the source colors while new creative detail is introduced.

### Key Capabilities <a href="#key-capabilities" id="key-capabilities"></a>

* Improved creative upscaling for GenAI images with new realistic detail and texture.
* Enhanced skin and facial detail for more natural-looking subjects.
* Creativity control from 1–10 for subtle enhancement through bold reinterpretation.
* Optional Face Recovery and Color Preservation for greater control over final results.

## 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/bloom/bloom-2-new-and-improved.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.
