ComfyUI Flux.2 Dev Example

This guide provides a brief introduction to the Flux.2 model and guides you through using the Flux.2 Dev model for text-to-image generation in ComfyUI.

About FLUX.2

FLUX.2 is a next-generation image model from Black Forest Labs, delivering up to 4MP photorealistic output with far better lighting, skin, fabric, and hand detail. It adds reliable multi-reference consistency (up to 10 images), improved editing precision, better visual understanding, and professional-class text rendering.

Key Features:

• Multi-Reference Consistency: Reliably maintains identity, product geometry, textures, materials, wardrobe, and composition intent across multiple outputs
• High-Resolution Photorealism: Generates images up to 4MP with real-world lighting behavior, spatial reasoning, and physics-aware detail
• Professional-Grade Control: Exact pose control, hex-code accurate brand colors, any aspect ratio, and structured prompting for programmatic workflows
• Usable Text Rendering: Produces clean, legible text across UI screens, infographics, and multi-language content

Available Models:

• FLUX.2 Dev: Open-source model (used in this tutorial)
• FLUX.2 Pro: API version from Black Forest Labs

We are using quantized weights in this workflow. The original FLUX.2 repository is available here.

Portable or self deployed users

Make sure your ComfyUI is updated.

• Download ComfyUI
• Update Guide

Workflows in this guide can be found in the Workflow Templates. If you can’t find them in the template, your ComfyUI may be outdated. (Desktop version’s update will delay sometime)

If nodes are missing when loading a workflow, possible reasons:

1. You are not using the latest ComfyUI version (Nightly version)
2. Some nodes failed to import at startup

Desktop or Cloud users

• The Desktop is base on ComfyUI stable release, it will auto-update when there is a new Desktop stable release available.
• Cloud will update after ComfyUI stable release.

So, if you find any core node missing in this document, it might be because the new core nodes have not yet been released in the latest stable version. Please wait for the next stable release.
