Introducing FLUX.1 Fill [dev]: State-of-the-Art Text-Guided Image Inpainting Now on WaveSpeedAI

The future of image editing is here. We’re thrilled to announce that FLUX.1 Fill [dev], Black Forest Labs’ groundbreaking 12-billion parameter inpainting model, is now available on WaveSpeedAI. This powerful tool brings professional-grade image editing capabilities to developers, artists, and businesses—all through a simple, lightning-fast API.

Whether you need to seamlessly replace objects, extend image boundaries, or transform visual content with natural language prompts, FLUX.1 Fill [dev] delivers results that were previously impossible without expensive proprietary solutions.

What is FLUX.1 Fill [dev]?

FLUX.1 Fill [dev] is a cutting-edge rectified flow transformer developed by Black Forest Labs, the team founded by the original creators of Stable Diffusion. Released in November 2024 as part of the FLUX.1 Tools suite, this model represents a significant leap forward in text-guided image inpainting technology.

At its core, FLUX.1 Fill [dev] enables you to modify specific areas of an image based on simple text descriptions. Provide a mask indicating what you want to change, describe your desired outcome in natural language, and watch as the model seamlessly blends new content into your existing image—maintaining lighting, style, and context with remarkable precision.

The model achieves this through guidance distillation training, making it significantly more efficient than comparable solutions while delivering output quality second only to the professional-tier FLUX.1 Fill [pro].

Key Features

• 12 Billion Parameters: A massive neural network architecture that understands complex visual relationships and generates highly detailed, coherent results

• Text-Guided Editing: Simply describe what you want in plain language—no complex technical knowledge required

• Seamless Blending: Edited regions integrate naturally with surrounding content, making changes virtually undetectable

• Inpainting Excellence: Fill in missing areas, replace objects, or modify specific elements while preserving the integrity of the original image

• Powerful Outpainting: Extend images beyond their original boundaries with contextually aware content generation

• Maximum Denoising Flexibility: Unlike traditional inpainting solutions, FLUX.1 Fill [dev] can use full denoising strength while maintaining consistency, allowing for dramatic color and content changes

• Superior Prompt Following: The model excels at understanding and executing complex prompts, translating your creative vision into precise visual results

How FLUX.1 Fill [dev] Outperforms the Competition

Benchmark comparisons consistently show FLUX.1 Fill [dev] outperforming popular alternatives. While SDXL inpainting models offer reasonable quality at lower resource costs, they often struggle with color tone consistency and seamless integration. FLUX.1 Fill [dev] eliminates these issues, delivering flawless results that blend naturally with your original imagery.

The model particularly excels in outpainting scenarios—extending images beyond their original borders with quality that remains unmatched by other solutions, including paid services. When it comes to preserving structure and maintaining visual coherence, FLUX.1 Fill [dev] sets the standard.
