Built on a revolutionary hybrid architecture combining a 24B parameter vision-language model with advanced rectified flow transformers, Flux 2 solves the industry's most persistent challenges: absolute character consistency, complex spatial reasoning, and photorealistic typography. Whether you are using the open-weight Flux 2 Dev for research or the Flux 2 Pro API for commercial production, you are accessing the most capable visual synthesis engine available today.
🚀 New in Flux 2: Upload up to 10 reference images for unparalleled style and character identity retention.
About the Model
What Is Flux 2 AI?
Flux 2 AI represents a quantum leap in the field of generative artificial intelligence. Developed by Black Forest Labs (BFL), the team behind the original Stable Diffusion innovations, Flux 2 is not merely an upgrade—it is a complete architectural reimaging of how machines understand and synthesize visual data. At its core, Flux 2 integrates a massive Mistral-3 24B parameter vision-language model (VLM) with a highly optimized Rectified Flow Transformer. This hybrid approach allows the model to possess 'visual reasoning' capabilities that far surpass traditional diffusion models. While previous generations relied on keyword probability, Flux 2 understands the semantic physics of your scene—the 'Who, How, and Why' of every pixel. Available in multiple variants including Flux 2 Dev (for open-weight experimentation), Flux 2 Pro (for enterprise pipelines), and Flux 2 Flex (for granular control), this ecosystem is designed to serve the entire spectrum of digital creation. From generating 4-megapixel ultra-high-resolution marketing assets to rendering complex UI mockups with perfect spelling, Flux 2 is the definitive tool for the next era of AI art.
Hybrid VLM Architecture
By coupling a 24B parameter vision-language model with flow matching, Flux 2 AI achieves superior prompt adherence, understanding complex spatial relationships (e.g., 'A cat sitting *inside* a glass box *on top* of a book').
4MP Native Resolution
Flux 2 pushes the boundaries of fidelity with native generation support up to 4 megapixels, delivering print-ready sharpness without the need for external upscalers.
Multi-Reference Consistency
The new identity-lock mechanism allows users to input up to 10 reference images, ensuring that characters, products, and styles remain identical across different scenes and angles.
Use Cases & Benefits
Why Creators and Developers Choose Flux 2 Dev & Pro
In a market flooded with generative tools, Flux 2 stands out by prioritizing controllability and production readiness. It addresses the specific pain points of professional workflows: the need for editable text, the demand for consistent assets, and the requirement for efficient local inference on consumer hardware (thanks to new FP8 quantization).
Advanced Typography and UI Design
Flux 2 AI has cracked the code on text generation. Designers can now generate full website mockups, book covers, and infographic elements with legible, perfectly aligned text, eliminating the 'gibberish' common in older models.
Open-Weight Innovation with Flux 2 Dev
For developers and researchers, Flux 2 Dev offers an open-weight 32B parameter model that can be fine-tuned and deployed locally. Optimized in collaboration with NVIDIA, it runs efficiently on RTX GPUs using FP8 quantization.
Sequential Storytelling for Comics & Film
With the ability to hold up to 10 reference inputs, Flux 2 enables the creation of graphic novels and storyboards where the protagonist's features never drift, maintaining visual narrative integrity from frame 1 to frame 100.

Frequently Asked Questions About Flux 2 AI
What is the difference between Flux 2 Dev, Flux 2 Pro, and Flux 2 Schnell?
Flux 2 Pro is the closed-source, state-of-the-art API model offering the highest fidelity and 4MP resolution. Flux 2 Dev is an open-weight, non-commercial model distilled from Pro, allowing for local installation and fine-tuning. Flux 2 Schnell (if available) is the turbo-distilled variant optimized for extreme speed and low-latency applications.
Can I use Flux 2 Dev for commercial projects?
The standard license for Flux 2 Dev is generally non-commercial. For commercial applications, you should use the Flux 2 Pro API or contact Black Forest Labs for a commercial license to host the Dev weights yourself.
How does Flux 2 compare to Flux 1?
Flux 2 offers a massive upgrade in prompt adherence and resolution (up to 4MP). The most significant addition is the multi-reference capability (up to 10 images) and the integration of a larger Vision-Language Model (Mistral-3) for better understanding of complex scenes.
What hardware do I need to run Flux 2 Dev locally?
To run the full FP16 model, you need significant VRAM (often 64GB+). However, using the optimized FP8 version in ComfyUI, you can run Flux 2 Dev on high-end consumer GPUs like the NVIDIA RTX 3090 or 4090 (24GB VRAM) with acceptable performance.
