# Flux 1.1 Pro Ultra Image Partner Nodes ComfyUI Official Workflow Examples

> This guide covers how to use the Flux 1.1 Pro Ultra Image Partner node in ComfyUI

FLUX 1.1 Pro Ultra is a high-performance AI image generation tool by BlackForestLabs, featuring ultra-high resolution and efficient generation capabilities. It supports up to 4MP resolution (4x the standard version) while keeping single image generation time under 10 seconds - 2.5x faster than similar high-resolution models.

The tool offers two core modes:

* **Ultra Mode**: Designed for high-resolution needs, perfect for advertising and e-commerce where detail magnification is important. It accurately reflects prompts while maintaining generation speed.
* **Raw Mode**: Focuses on natural realism, optimizing skin tones, lighting, and landscape details. Reduces the "AI look" and is ideal for photography and realistic style creation.

## What Flux 1.1 Pro Ultra Image is good at

* **Ultra-high resolution**: Generates images up to 4MP, 4x the standard version's resolution
* **Fast generation**: Keeps single image generation time under 10 seconds, 2.5x faster than similar high-resolution models
* **Prompt accuracy at scale**: Ultra Mode reflects prompts accurately while maintaining generation speed, suited to advertising and e-commerce work
* **Natural realism**: Raw Mode optimizes skin tones, lighting, and landscape details to reduce the "AI look"
* **Image-to-image remixing**: An `image_prompt` input blends features from an input image, with `image_prompt_strength` controlling the blend ratio
