FLUX 3 Image - Oxen.ai

Try FLUX 3 Image in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: flux-3-image FLUX 3 Image generates images from a text prompt, edits an existing image from a written instruction, and combines up to ten reference images into one output. Output ranges from 768 x 768 drafts to roughly 16 megapixels at 4K, across 15 aspect ratios from 21:9 to 9:21. Edits name what to change and leave the rest of the image untouched: recolor, replace, move or remove an element, or restyle the whole frame. With several references, each image is cited by its position (“image 1”, “image 2”) and can supply a subject, product, setting or style. For exact placement, a JSON list of bounding boxes appended to the prompt positions each element on a 0 to 1000 grid, both for new layouts and for targeted edits. Optional grounding lets the model search the web and images so real places, products and events are rendered accurately; without it, generation is faster and uses the prompt alone.

Request parameters

Required parameters

Field	Type	Default	Description
`prompt`	`string`	—	Prompt for the generated image. Use @Image1, @Image2, etc. to reference the input images.

Optional parameters

Field	Type	Default	Description
`input_image`	`array<string>`	—	Input images to edit or use as reference, up to 10. Reference them in the prompt as @Image1, @Image2, etc.
`aspect_ratio`	`string`	`"auto"`	Aspect Ratio One of: auto, 21:9, 2:1, 16:9, 3:2, 7:5, 4:3, 5:4, 1:1, 4:5, 3:4, 5:7, 2:3, 9:16, 1:2, 9:21.
`resolution`	`string`	`"1k"`	Resolution One of: 768sq, 1k, 2k, 4k.
`grounding`	`boolean`	`false`	Search the web and images before generating, so real places, products and events come out right. Slower than generating from the prompt alone.
`safety_tolerance`	`integer`	`2`	Safety filter strictness, 0 is strictest. One of: 0, 1, 2, 3, 4.
