Nano Banana Pro is Google's new state-of-the-art image generation and editing model Pricing (from fal, 2026-09-30): Your request will cost $0.15 per image. For $1.00, you can run this model 7 times. 4K outputs will be charged at double the standard rate. If web search is used, an additional $0.015 will be charged. Note: Pricing may change in the future. Model page: https://fal.ai/models/fal-ai/nano-banana-pro Key: FAL_KEY in the .env next to run_nvidia_gpu.bat. Results are saved in output/fal/fal-ai_nano-banana-pro/.

Inputs (14)
| Name | Type | Default | Description |
|---|---|---|---|
| prompt | STRING | The text prompt to generate an image from. | |
| num_images | INT | 11–4 | The number of images to generate. |
| seed | INT | -1-1–2147483647 | The seed for the random number generator. -1 leaves it to the model. |
| aspect_ratio | COMBO | 1:1 | The aspect ratio of the generated image. |
| output_format | COMBO | png | The format of the generated image. |
| safety_tolerance | COMBO | 4 | The safety tolerance level for content moderation. 1 is the most strict (blocks most content), 6 is the least strict. |
| system_prompt | STRING | Optional system instruction that steers the model's persona and output style across the request. Leave blank to omit; when provided, it is sent as the system instruction to Gemini (or as a system message on OpenAI-compatible providers). Empty leaves it out. | |
| resolution | COMBO | 1K | The resolution of the image to generate. |
| limit_generations | BOOLEAN | true | Experimental parameter to limit the number of generations from each round of prompting to 1. Set to `True` to to disregard any instructions in the prompt regarding the number of images to generate. |
| enable_web_search | BOOLEAN | false | Enable web search for the image generation task. This will allow the model to use the latest information from the web to generate the image. |
| 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. |
