Flux 2 Dev on AI Compare Hub
Flux 2 Dev is Black Forest Labs' most powerful open-weight text-to-image AI—a 32-billion parameter model with multi-image input and advanced editing. The frontier of open-source image generation delivering professional-quality results with unmatched creative flexibility.
What you can create
-
Character and style consistency across projects
Combine up to 10 reference images to maintain character consistency, visual style, and compositional elements across multiple generated images. Perfect for character design series and cohesive art projects.
-
Complex brand asset variations
Generate product variations, packaging designs, and marketing materials that maintain strict brand consistency while adapting to different contexts and sizes.
-
Advanced image editing and transformation
Edit existing images using natural text instructions—modify scenes, change elements, adjust lighting, and transform compositions without traditional photo editing software.
-
Structured data-driven creative work
Use JSON prompting for granular control over image generation, enabling systematic asset creation for design systems, templated content, and data-driven workflows.
Why creators choose Flux 2 Dev
-
32 billion parameters for frontier quality
Flux 2 Dev's 32-billion parameter scale, combined with a Mistral-3 24B vision-language model, delivers unmatched creative capability and scene understanding. This architecture brings real-world knowledge and spatial reasoning to image generation.
-
Multi-reference consistency up to 10 images
Flux 2 Dev can reference up to 10 input images simultaneously, extracting and combining visual concepts, styles, characters, and compositional elements into novel outputs. This enables unprecedented creative control and consistency workflows impossible with single-image models.
-
Up to 4 megapixel editing resolution
The model edits images at resolutions up to 4 megapixels while maintaining detail, coherence, and prompt adherence. High-resolution editing enables professional-grade output refinement and upscaling tasks.
-
Local deployment and research use
Flux 2 Dev weights are freely available on Hugging Face for research and personal use. The model runs locally using optimized FP8 implementations with NVIDIA and ComfyUI support on consumer-grade GPUs, giving researchers full control without API restrictions.
How to generate your first image
- Write your prompt. Describe your creative vision in detail. Flux 2 Dev excels at complex multi-part instructions, scene descriptions, and nuanced direction. Include reference styles, brand guidelines, and specific requirements.
- Configure your settings. Upload reference images (up to 10) if using multi-image input mode. Select your output resolution and editing parameters if refining existing images. Specify any JSON constraints for advanced control.
Common questions
What is Flux 2 Dev?
Flux 2 Dev is Black Forest Labs' second-generation open-weight AI image generator—a 32-billion parameter flow matching transformer capable of generating and editing images. It's the most powerful open-source model available, supporting multi-image inputs for consistency, up to 4MP editing, JSON prompting, and both text-to-image and image-to-image workflows.
How does Flux 2 Dev handle multiple reference images?
Flux 2 Dev can process up to 10 reference images simultaneously, intelligently extracting and combining their visual concepts, styles, character appearances, and compositional elements into a unified new image. This enables character consistency, style transfer, and complex creative control impossible with traditional single-reference models.
Can I edit existing images with Flux 2 Dev?
Yes. Flux 2 Dev performs advanced image editing through natural text instructions. You can modify scenes, replace elements, adjust lighting, change colors, and transform entire compositions at resolutions up to 4 megapixels while maintaining image quality and coherence.

For the Use of This Model
The FLUX.2 Dev model by Black Forest Labs is a developer-oriented image generation model built for experimentation, testing, and integration workflows.
It is ideal for prompt iteration, feature validation, and technical evaluation rather than final production output.
Before you use it on AI Compare Hub, please keep in mind:
- Use responsibly.
Do not create or share content that is harmful, misleading, or that violates the rights of others. You are fully responsible for the prompts you submit and how you use the generated images. - Outputs & responsibility.
You control the images you generate. Black Forest Labs does not claim ownership of your outputs, but their terms allow the use of inputs and outputs as necessary to operate and improve their services. You are responsible for ensuring compliance with copyright, privacy, and applicable laws. - Development-focused performance.
FLUX.2 Dev prioritizes flexibility and speed over maximum polish. Output quality and consistency may vary depending on prompts and parameters. - Pricing structure.
Pricing is usage-based and calculated according to the megapixel size of any input images and the megapixel size of the generated output images. Costs accrue based on actual generation usage rather than a fixed per-image fee. - No guarantees.
Images are generated probabilistically and may not always match your intent. The model and service are provided “as is,” without warranties or guarantees. - Terms of use.
Your use of this model is governed by Black Forest Labs’ API Service Terms. - Restrictions reminder.
The provider’s terms prohibit certain uses, including training or building competing AI models using the outputs, as well as any unlawful or restricted activities.
Your use of this feature is also subject to this site’s Terms of Service.
