Flux 3 Image generates an image with FLUX 3 from a prompt, or edits and combines reference images. Write what you want as an instruction, then connect up to 10 reference images and refer to them in the prompt as image 1, image 2, and so on. The prompt is interpreted and expanded before generation, and the result is rendered at the aspect ratio and resolution you choose. ## Inputs | Parameter | Description | Data Type | Required | Range | | - | - | - | - | - | | `prompt` | What to generate, or the edit to make. The prompt is interpreted and expanded before generation. Refer to connected reference images as image 1, image 2, and so on. (default: "") | STRING | Yes | 1 to 15000 characters | | `images` | Growable slot for reference images; connect up to 10 in total. Each image must be at least 256x256 pixels, and its aspect ratio cannot be more extreme than 64:1. | IMAGE | No | 0 to 10 images | | `bounding_boxes` | Optional boxes from the Create Bounding Boxes node that place objects or text in the output. Positions are relative to the canvas, so give the node the output's aspect ratio. | ARRAY | No | - | | `aspect_ratio` | Aspect ratio of the generated image. "auto" follows the first reference image, or picks a ratio from the prompt. (default: "auto") | COMBO | Yes | `"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` | Output size at the chosen aspect ratio: 0.75K is about 0.6 megapixels, 1K 1 MP, 1.5K 2.4 MP, 2K 4.2 MP, 4K 16.8 MP. (default: "2K") | COMBO | Yes | `"0.75K"`
`"1K"`
`"1.5K"`
`"2K"`
`"4K"` | | `grounding` | Let the model research the prompt with web and image search before generating. (default: True) | BOOLEAN | Yes | True
False | | `safety_tolerance` | Moderation tolerance, 0 is the strictest. (default: 4) | INT | Yes | 0 to 4 | | `seed` | Seed to determine if node should re-run; FLUX 3 picks its own seed, so actual results are nondeterministic regardless of this value. (default: 42) | INT | Yes | 0 to 4294967295 | `safety_tolerance` is an advanced input, and `seed` includes Control After Generate controls in the UI. Reference images are uploaded before the request is sent. A single slot can carry a batch, and every frame of every batch counts towards the limit of 10 images. `bounding_boxes` rows are appended to the prompt, so the prompt and the box descriptions must be 15000 characters or fewer together. The displayed price depends on `resolution`: $0.05863 at 0.75K, $0.06864 at 1K, $0.1001 at 1.5K, $0.143 at 2K and \$0.86801 at 4K. ## Outputs | Output Name | Description | Data Type | | - | - | - | | `IMAGE` | The generated image, downloaded from the FLUX 3 result. | IMAGE | > This documentation was AI-generated.
