Inputs (16)
| Name | Type | Default | Description |
|---|---|---|---|
| prompt | STRING | The prompt to generate a realistic image with natural lighting and authentic details. | |
| image_size | COMBO | landscape_4_3 | The size of the generated image. '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'. |
| guidance_scale | FLOAT | 2.500–20 | The CFG (Classifier Free Guidance) scale. Controls how closely the model follows the prompt. |
| num_inference_steps | INT | 404–50 | The number of inference steps to perform. |
| acceleration | COMBO | regular | Acceleration level for image generation. 'regular' balances speed and quality. |
| seed | INT | -1-1–2147483647 | Random seed for reproducibility. Same seed with same prompt will produce same result. -1 leaves it to the model. |
| enable_safety_checker | BOOLEAN | true | Whether to enable the safety checker for the generated image. Disabling it requires account authorization; unauthorized requests are always checked. |
| output_format | COMBO | png | The format of the output image |
| num_images | INT | 11–4 | Number of images to generate |
| lora_scale | FLOAT | 1.000–2 | The strength of the realism effect. |
| 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. |
