# Bloom 2 — New & Improved!

Higher-quality creative upscaling for GenAI images with new, reimagined details

### 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.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://developer.topazlabs.com/image-models/bloom/bloom-2-new-and-improved.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
