Inputs (20)
| Name | Type | Default | Description |
|---|---|---|---|
| prompt | STRING | Text prompt describing the desired edit. Supports Chinese and English. Max 5000 characters. | |
| negative_prompt | STRING | Content to avoid in the generated image. Max 500 characters. Empty leaves it out. | |
| image_size | COMBO | square_hd | The size of the generated image. If not provided, the model determines the resolution automatically. Total number of pixels must be between 512x512 and 2048x2048. 'custom' uses the width and height below. |
| image_size_width | INT | 102416–14142 | Width in pixels when image_size is 'custom'. |
| image_size_height | INT | 102416–14142 | Height in pixels when image_size is 'custom'. |
| enable_prompt_expansion | BOOLEAN | true | Enable automatic LLM prompt rewriting for better results. |
| seed | INT | -1-1–2147483647 | Random seed for reproducibility (0-2147483647). -1 leaves it to the model. |
| enable_safety_checker | BOOLEAN | true | Enable content moderation for input and output. Disabling it requires account authorization; unauthorized requests are always checked. |
| num_images | INT | 11–6 | The number of images to generate. |
| output_format | COMBO | png | The format of the generated image. |
| image_1 | IMAGE | Reference images for editing (1-3 images required). Order matters: reference as 'image 1', 'image 2', 'image 3' in prompt. Resolution: 384-2048px each dimension. Max size: 10MB each. Formats: JPEG, JPG, PNG (no alpha), WEBP. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_2opt | IMAGE | Reference images for editing (1-3 images required). Order matters: reference as 'image 1', 'image 2', 'image 3' in prompt. Resolution: 384-2048px each dimension. Max size: 10MB each. Formats: JPEG, JPG, PNG (no alpha), WEBP. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_3opt | IMAGE | Reference images for editing (1-3 images required). Order matters: reference as 'image 1', 'image 2', 'image 3' in prompt. Resolution: 384-2048px each dimension. Max size: 10MB each. Formats: JPEG, JPG, PNG (no alpha), WEBP. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_4opt | IMAGE | Reference images for editing (1-3 images required). Order matters: reference as 'image 1', 'image 2', 'image 3' in prompt. Resolution: 384-2048px each dimension. Max size: 10MB each. Formats: JPEG, JPG, PNG (no alpha), WEBP. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_5opt | IMAGE | Reference images for editing (1-3 images required). Order matters: reference as 'image 1', 'image 2', 'image 3' in prompt. Resolution: 384-2048px each dimension. Max size: 10MB each. Formats: JPEG, JPG, PNG (no alpha), WEBP. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_6opt | IMAGE | Reference images for editing (1-3 images required). Order matters: reference as 'image 1', 'image 2', 'image 3' in prompt. Resolution: 384-2048px each dimension. Max size: 10MB each. Formats: JPEG, JPG, PNG (no alpha), WEBP. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| max_cost_usdopt | FLOAT | 20.00–100000 | Safety cap. If the estimated cost of this run is above this many US dollars the node stops BEFORE sending anything to fal. 0 = no cap. |
| reuse_identical_runopt | BOOLEAN | true | If these exact inputs (the settings AND the same pictures/clips/audio) were already paid for and the files are still in output/fal, return them instead of paying again - also after a ComfyUI restart. Turn off for a fresh take with the same settings. |
| extra_jsonopt | STRING | Advanced: a JSON object merged into the request last, for any fal field this node has no box for. Example: {"seed": 7}. Leave empty normally. | |
| max_concurrentopt | INT | 11–32 | How many paid fal calls may run at the same time in one run, across every fal node. 1 (default) = one after another. This node starts its paid part only while fewer than this many fal calls are running. Once any fal node fails, the ones still waiting are not started, so nothing more is billed. |
