Flux 3 Image Edit
Flux 3 Image Edit is Black Forest Labs' newest image editing model. Make
precise, local edits (add, replace, remove or restyle one element) without
changing the rest of the image, or combine up to 10 reference images into one
well-composed result.
For generation from text alone, use
Flux 3 Image.
Highlights
- Precise local editing. Change one object, color or region and everything
else stays as it was: identity, pose, lighting, background and framing.
- Multi-reference generation and editing. Combine up to 10 references
while keeping characters, products and objects recognizable.
- Reference-based style transfer. Apply the look of one image to the
content and composition of another.
- Text editing. Change or add text inside an image.
- One flat price per image, whatever the number of references.
Parameters
| Parameter | Values | Notes |
|---|
prompt | text | Required. Describes the edit. |
image_urls | 1 to 10 image URLs | Required. Each image must be at least 256px per side and at most 4MP. Order matters: the first URL is image 1. |
resolution | 512sq, 768sq, 1k (default), 2k, 4k | Higher tiers take longer. |
aspect_ratio | auto (default) or a fixed ratio | auto matches image 1. |
enable_prompt_expansion | true / false (default) | Clarifies the prompt and makes each reference's role explicit. |
safety_tolerance | 0 (strictest) to 4, default 2 | |
output_format | jpeg (default), png | |
Prompting tips
- Name the one change. Short, direct instructions work best:
Turn the white heart into a red heart.
- Be specific about which element. Write
change the color of only one bird in the middle to #e01075, not
"change a bird's color".
- Refer to references by number. Write
Replace the sunglasses in image 1 with the round pink-tinted sunglasses from image 3.
Image 1 is the first URL in image_urls.
- For style transfer, say which image supplies what. Write
Turn image 1 in the style of image 2.
- Make one edit per request. Chain several small edits instead of one
large rewrite.
Example prompts
change the color of only one bird in the middle to #e01075
Replace the Background in Image 1 with the fabric pattern from image 2
