Technical Overview

How FLUX.1 Fill Works

FLUX.1 Fill uses advanced neural networks to understand image context and generate content that seamlessly integrates with the original. Here's what powers it.

  • Context-Aware Generation

    Analyzes surrounding pixels and image semantics to generate coherent fill content.

  • Mask-Based Selection

    Binary masks or alpha channels precisely define edit regions for targeted modifications.

  • Flow Transformer Architecture

    12 billion parameter model using rectified flow matching for high-quality outputs.

  • Text-Prompt Conditioning

    Natural language descriptions guide what content to generate in masked areas.

💡 Pro Tip

For best inpainting results, ensure your mask clearly covers the entire area you want to change. For outpainting, start with smaller extensions and work iteratively for better continuity.

Frequently Asked Questions

Everything you need to know about FLUX.1 Fill and AI-powered image editing.

What is FLUX.1 Fill?
FLUX.1 Fill is a 12-billion parameter AI model from Black Forest Labs designed for inpainting (editing specific regions) and outpainting (extending images beyond their borders). It uses text prompts and masks to precisely control what to edit or generate.
What's the difference between inpainting and outpainting?
Inpainting modifies specific regions within an image—like removing objects or replacing elements. Outpainting extends the image beyond its original borders, generating new content that continues the scene naturally.
What kind of images can FLUX.1 Fill edit?
FLUX.1 Fill works with both real photographs and AI-generated images. It's effective for landscapes, portraits, product photos, artwork, and virtually any image where you need to edit or expand specific areas.
How do masks work in FLUX.1 Fill?
Masks define which areas to edit. White areas in the mask indicate regions to fill/regenerate, while black areas are preserved. You can use binary black/white masks or alpha channels for more precise control.
Is FLUX.1 Fill free to use?
Yes! On Red Panda AI, you can use FLUX.1 Fill completely free with no sign-up required. Generate unlimited edits without any hidden costs or watermarks.
How does FLUX.1 Fill compare to other inpainting tools?
FLUX.1 Fill outperforms competing tools in benchmarks, including Ideogram 2.0 and many open-source alternatives. Its 12B parameter architecture and flow transformer technology deliver superior quality and more natural-looking results.
