Inputs (18)

Name	Type	Default	Description
prompt	STRING		The prompt to generate an image from.
image_size	COMBO	auto	The size of the generated image. If `auto`, the size will be determined by the model. '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'.
seed	INT	-1-1–2147483647	The seed to use for the generation. -1 leaves it to the model.
safety_tolerance	COMBO	2	The safety tolerance level for the generated image. 1 being the most strict and 5 being the most permissive.
enable_safety_checker	BOOLEAN	true	Whether to enable the safety checker. Disabling it requires account authorization; unauthorized requests are always checked.
output_format	COMBO	jpeg	The format of the generated image.
image_1	IMAGE		List of URLs of input images for editing Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1).
image_2opt	IMAGE		List of URLs of input images for editing Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1).
image_3opt	IMAGE		List of URLs of input images for editing Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1).
image_4opt	IMAGE		List of URLs of input images for editing Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1).
image_5opt	IMAGE		List of URLs of input images for editing Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1).
image_6opt	IMAGE		List of URLs of input images for editing 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.
