FLUX family of models

Which models are the fastest?

If you want rapid generation or real-time results, black-forest-labs/flux-schnell is built for speed. It’s great for prototypes, interactive tools, or local applications where quick iteration matters most.

For editing tasks, black-forest-labs/flux-redux-schnell provides fast image variation and restyling while keeping core visual elements intact.

Which models offer the best balance of cost and quality?

black-forest-labs/flux-1.1-pro delivers the best mix of image quality, versatility, and efficiency. It’s suitable for both creative and professional work and performs well across a variety of prompts.

If you need slightly higher fidelity or larger output sizes, black-forest-labs/flux-1.1-pro-ultra gives you 4-megapixel images and enhanced realism, especially in “raw” mode.

What works best for creating new images from text?

For pure text-to-image generation, black-forest-labs/flux-1.1-pro-ultra produces the most detailed, photorealistic images, while black-forest-labs/flux-1.1-pro is a more efficient alternative with similar style control.

If you’re experimenting or building lightweight apps, black-forest-labs/flux-schnell is ideal for quick generation with good visual coherence.

What works best for editing existing images?

If you’re editing or extending images, black-forest-labs/flux-fill-pro is the top choice for inpainting and outpainting—it blends additions naturally and can remove or replace objects seamlessly.

For structure-preserving edits (like retexturing or adjusting composition while maintaining depth or edges), black-forest-labs/flux-depth-pro and black-forest-labs/flux-canny-pro give you fine control over spatial relationships and outlines.

What’s the difference between key subtypes or approaches in this family?

The FLUX family has three main groups:

• Text-to-Image models (black-forest-labs/flux-1.1-pro, black-forest-labs/flux-1.1-pro-ultra, black-forest-labs/flux-schnell): Generate images from scratch using natural language prompts.
• Image Editing models (black-forest-labs/flux-fill-pro, black-forest-labs/flux-depth-pro, black-forest-labs/flux-canny-pro): Modify existing images with natural or structural guidance.
• Variation and Fine-tuning models (black-forest-labs/flux-redux, black-forest-labs/flux-pro-finetuned, black-forest-labs/flux-pro-trainer): Create new versions of an image or train your own custom model for consistent characters or branded aesthetics.

What kinds of outputs can I expect from these models?

Most FLUX models output high-resolution images up to 4 megapixels, depending on the variant.

Editing models (like black-forest-labs/flux-fill-pro or black-forest-labs/flux-depth-pro) produce updated versions of your original image, while text-to-image models generate entirely new images based on your prompt.

How can I self-host or push a model to Replicate?

You can run open-weight versions such as black-forest-labs/flux-dev, black-forest-labs/flux-fill-dev, or black-forest-labs/flux-depth-dev locally using Cog or Docker.
To publish your own fine-tuned model, train it using black-forest-labs/flux-pro-trainer with a set of images, then use the resulting finetune_id to run your customized version with black-forest-labs/flux-pro-finetuned.

Can I use these models for commercial work?

Yes—most FLUX models are licensed for commercial use, especially black-forest-labs/flux-1.1-pro and black-forest-labs/flux-1.1-pro-ultra.

Always check the License section on the model’s page for confirmation, particularly if you’re deploying outputs at scale or selling generated assets.

How do I use or run these models?

Go to a model’s page on Replicate, upload an input image (if editing) or type a text prompt (if generating from scratch).

Choose optional parameters like raw mode, creativity, or guidance strength to control realism and variation. Then run the model to preview and download the output.

What should I know before running a job in this collection?

• Use descriptive, natural prompts—FLUX models follow text closely.
• If realism is important, enable raw mode on Pro Ultra or lower the creativity setting on editing models.
• Large outputs (4MP) take more compute; for previews or experiments, start with smaller image sizes.
• For consistent characters or branded imagery, fine-tune using black-forest-labs/flux-pro-trainer.

Any other collection-specific tips or considerations?

• Use black-forest-labs/flux-kontext-pro or black-forest-labs/flux-kontext-max if you need text-based editing or typography integration.
• black-forest-labs/flux-redux is great for generating cohesive variations—perfect for creative teams iterating on a design.
• The Dev versions (e.g., black-forest-labs/flux-dev, black-forest-labs/flux-fill-dev) are open weights—ideal for research or custom deployments.
• You can chain FLUX models: for example, generate an image with black-forest-labs/flux-1.1-pro, then edit it using black-forest-labs/flux-fill-pro or retexture it with black-forest-labs/flux-depth-pro.
