FLUX.2 Release: The New Open-Source King with 4MP Editing & 10-Image Blending

November 25, 2025 - The wait is over. Black Forest Labs has officially dropped FLUX.2, the next evolution in their open-source image generation family.

This isn't just a version bump. FLUX.2 represents a massive consolidation of power. It unifies text-to-image generation, in-painting, and advanced multi-reference generation into a single powerhouse. Think of it as the raw quality of FLUX.1 combined with a supercharged version of FLUX.1 Kontext.

Most impressively, FLUX.2 now supports native image editing at up to 4 Megapixels (4MP) while maintaining perfect structural integrity.

What's the New Features of FLUX.2

Multi-Reference

This is a game-changer for consistency. You can now input up to 10 reference images simultaneously.

High-Definition Detail & Realism

FLUX.2 delivers sharper textures and more stable lighting physics. It is optimized for product visualization and photorealistic applications where "good enough" isn't enough.

Next-Gen Text Rendering

FLUX.2 handles complex typography with ease. Whether it's infographics, memes, or high-fidelity UI mockups, even small text remains crisp and legible.

Precise Color Control

For designers, color accuracy is non-negotiable. FLUX.2 offers:

• Hex Code Precision: Input exact color codes to match brand guidelines.
• Gradient Control: Define specific start and end colors for backgrounds or elements.

Enhanced World Knowledge

The model's understanding of real-world logic, lighting, and spatial awareness has been significantly upgraded. Objects interact with light sources naturally, making scenes look physically grounded rather than "dream-like."

4MP Resolution Editing

Edit and refine images at a massive 4 megapixels. This allows for professional-grade retouching and variable aspect ratios without losing quality.

Different Versions of FLUX.2

Which version is right for you? Here is the breakdown:

• FLUX.2 [pro]: The state-of-the-art flagship. It rivals top closed-source models, offering the best prompt adherence and visual fidelity while being optimized for speed and lower cost. Perfect for enterprise use.
• FLUX.2 [flex]: The developer's choice. It grants full parameter control, allowing you to tweak steps and guidance strength to balance quality vs. speed. It excels particularly in text rendering.
• FLUX.2 [dev]: A 32B parameter open-weight model. Currently the most powerful open-source model for generation and editing, unifying multiple workflows into one checkpoint.
• FLUX.2 [klein] (Coming Soon): A lightweight, distilled version under the Apache 2.0 license. It promises to be stronger than models trained from scratch at the same size, retaining the core capabilities of its larger teachers.

Model Face-Off: FLUX.2 vs. Nano Banana Pro

Test 1: Photorealism & Detail

Prompt: Soaking wet tiger cub taking shelter under a banana leaf in the rainy jungle, close up photo.

Test 2: Products In Context

Prompt: The jar in image 1 is filled with capsules exactly same as image 2 with the exact logo.

Test 3: Multi-Reference

Prompt: Replace the children in the image with the animals from images 2, 3, 4,5, and 6. Adjust them to the space and style so they sit naturally in the scene. Adjust the proportions of the animals to each other and to the space.
