FLUX.1 Pro

FLUX.1 Pro - Professional AI Image Generation

FLUX.1 Pro is the most advanced text-to-image generation model developed by Black Forest Labs, representing the pinnacle of AI image generation technology. Based on a hybrid architecture of multimodal and parallel diffusion transformer blocks scaled to 12 billion parameters, the model sets a new standard in the image generation field.

Core Features

Outstanding prompt understanding
FLUX.1 Pro excels at interpreting and accurately representing complex text prompts, precisely understanding user intent and generating the corresponding visual content. The model matches DALL-E 3 in prompt fidelity and approaches Midjourney 6's level of realism.

Top-tier visual quality
The model generates images with stunning detail, realism, and aesthetics across a wide range of styles and subjects. It supports multiple aspect ratios and resolutions between 0.1 and 2.0 megapixels, giving users flexible creative space from standard formats to panoramic or portrait orientations.

Diverse output capability
It offers rich creative interpretations for each prompt, enabling varied visual exploration. The model renders human hands more consistently than earlier models like Stable Diffusion XL.

Model Variants

FLUX.1 Pro 1.1
The improved flagship model released on October 2, 2024, adding an Ultra mode (supporting 4x higher resolution and generation up to 4 megapixels) and a Raw mode (generating ultra-realistic candid photography-style images).

FLUX.1 Kontext
The context-aware image generation and editing suite released on May 29, 2025, allowing users to prompt with both text and images for seamless visual concept extraction and modification.

Professional Use Cases

Graphic design and branding
Designers can prototype quickly, explore new creative directions, and streamline workflows. FLUX.1's clear text rendering and precise color control are a perfect fit for logo design and marketing materials.

Concept art and game development
It excels at rapidly creating and iterating on characters, environments, and objects, making it a vital tool for world-building in film, games, and graphic novels.

Publishing and the music industry
Independent artists can easily create impressive album covers; the model performs excellently on professional-grade album artwork with proper typography integration and visual themes.

Technical Advantages

Flow matching architecture
Trained with an innovative flow matching approach—a general and conceptually simple method for training generative models that includes diffusion as a special case.

High-performance benchmarks
FLUX 1.1 Pro outperforms all other models on the Artificial Analysis image arena benchmark, earning the highest overall Elo score.

Fast generation
Each image takes only 10 seconds to generate, ideal for fast-paced professional workflows. FLUX Kontext's sub-10-second generation times keep creative momentum flowing.

Access

FLUX.1 Pro is provided through Black Forest Labs' API and is also accessible via partners Replicate and fal.ai. The model offers a simple, easy-to-integrate API to access the latest and most powerful FLUX models, built to handle production workloads of any scale.

Developers can experiment with FLUX's most advanced models in the browser playground to test ideas and iterate on prompts. For commercial use, licensing is available at https://bfl.ai/pricing/licensing, with fees based on monthly usage automatically tracked through the BFL API.
