Frequently asked
What is an AI image generator?
An AI image generator creates a new image from a description. Tell it what you want to see, including the subject, setting, lighting, and visual style. You can also upload a reference image to guide the result.
Which model does this tool use?
This tool uses FLUX 3 Klein by Black Forest Labs. Text prompts use its text-to-image model. Adding a reference automatically switches to its image-editing model. The model is always shown above the prompt.
Can I generate an image without uploading anything?
Yes. The reference image is optional. Enter a prompt and select Generate to create an image from text alone.
How do I use a reference image?
Upload one JPEG, PNG, or WebP image up to 20 MB, then describe the image you want to create. Mention what should stay and what should change: for example, keep the product and place it on a sunlit kitchen counter.
Is the AI image generator free?
Free runs are available when this page has an active program and you have runs remaining. The generator shows your availability before you run. Otherwise, sign in and use your fal credits.
What size and format will I get?
Each run creates one PNG image. Choose square at 1024 × 1024, landscape at 1152 × 864, or portrait at 864 × 1152. Signed-in users can download the full image; guests can download a preview and sign up for the full image.
Can I use this model through an API?
Yes. Both FLUX 3 Klein text-to-image and image editing are available through the fal API. Open the model playground for API documentation, reproducible seeds, and more output settings.
Finish the job with the other tools.
