| Parameter name | Type | Default value | Value range | Description |
|---|---|---|---|---|
| model | string | "flux-dev" | Fixed to "flux-dev" | The model name used, currently only "flux-dev" is supported |
| prompt | string | - | - | Text prompt used to generate images, required. The content of the prompt will directly affect the content and style of the generated image. You need to describe the image you want to generate as detailed and specific as possible |
| image | string | - | - | Input image for image to image mode. The output image will have the same aspect ratio as this image. Images need to be provided in the form of URI, supporting http/https URL or data URL (base64 encoded image data) |
| prompt_strength | number | 0.8 | 0~1 | In image-to-image mode, the strength of the text prompt relative to the input image. When the value is 1, the information in the input image will be completely replaced, that is, the generated image has nothing to do with the input image. When the value is 0, the input image will be completely retained and the text prompt will have no effect. The recommended value is between 0.6~0.9 |
| num_outputs | integer | 1 | 1~4 | Number of images to generate |
| aspect_ratio | string | "1:1" | "1:1", "16:9", "21:9", "2:3", "3:2", "4:5", "5:4", "9:16", "9:21" | Generate the aspect ratio of the image, providing some common aspect ratio options, please choose according to your needs |
| num_inference_steps | integer | 50 | 1~50 | The number of inference steps for sampling. The larger the number of inference steps, the higher the image quality, but the longer the generation time. The recommended setting is between 28~50 |
| guidance | number | 3.5 | 0~10 | Controls the balance between the relevance of generated images to text hints and image quality/diversity. Valid in flux-dev model, ignored in flux-schnell model. A higher value (such as 7) will cause the output to more closely match the prompt, but may reduce the overall quality and diversity of the image. Lower values (such as 2) allow more creative freedom, but the resulting image may be less relevant to the prompt. It is recommended to take a value between 3 and 5 |
| seed | integer | - | 0~2^32-1 | Random seed. If seed is set, the image generated is certain each time. If seed is not set, the images generated each time will be random. Setting the seed allows you to get reproducible generation results |
| output_format | string | "webp" | "webp", "jpg", "png" | The format of the output image. Three common web-friendly formats are provided. If there are no special needs, it is recommended to use the default webp format |
| output_quality | integer | 80 | 0~100 | The quality of the output image, only valid for jpg and webp formats. 100 represents the best quality, 0 represents the lowest quality. If you want to strike a balance between image quality and file size, it is recommended to set it to around 80 |
| disable_safety_checker | boolean | true | true, false | Whether to disable the content safety checker. The default is true, which means no content security check is performed to minimize the impact of the filter on user use. |
| response_format | string | "url" | "url", "b64_json" | The returned image data format, the image address is returned in the form of url by default. If set to "b64_json", the image data will be returned directly in base64 encoding in json, saving additional network requests, but the amount of response data will increase |
