Bloom 2 — New & Improved!

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

Model Overview

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

• 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.
