arkennemasis fal · Nano Banana 2 Edit · $0.06-0.16/image
Nano Banana 2 is Google's new state-of-the-art image generation and editing model Pricing (from fal, 2026-09-30): Your request will cost $0.08 per image. For $1.00, you can run this model 12 times. 2K and 4K outputs will be charged at 1.5 times and 2 times the standard rate, respectively. 0.5K (512px) resolution outputs will be charged at 0.75 times the standard rate. If web search is used, an additional $0.015 will be charged. If high thinking is used, an additional $0.002 will be charged. Note: Pricing is subject to change. Model page: https://fal.ai/models/fal-ai/nano-banana-2/edit Key: FAL_KEY in the .env next to run_nvidia_gpu.bat. Results are saved in output/fal/fal-ai_nano-banana-2_edit/.

Inputs (24)
| Name | Type | Default | Description |
|---|---|---|---|
| prompt | STRING | The prompt for image editing. | |
| 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 | auto | The aspect ratio of the generated image. Supports extreme ratios: 4:1, 1:4, 8:1, 1:8. |
| 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. |
| pdf_url | STRING | Optional PDF document to use as input context. Accepts an http(s)/data URL (downloaded and sent inline, max 15MB). Paste a link; leave empty to leave it out. | |
| 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 and ignore any intermediate images generated by the model. This may affect generation quality. |
| 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. |
| thinking_level | COMBO | (not set) | When set, enables model thinking with the given level ('minimal' or 'high') and includes thoughts in the generation. Omit to disable. '(not set)' leaves it to the model. |
| image_1opt | IMAGE | The URLs of the images to use for image-to-image generation or image editing. Optional when at least one of `video_url`, `audio_url`, or `pdf_url` is provided. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_2opt | IMAGE | The URLs of the images to use for image-to-image generation or image editing. Optional when at least one of `video_url`, `audio_url`, or `pdf_url` is provided. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_3opt | IMAGE | The URLs of the images to use for image-to-image generation or image editing. Optional when at least one of `video_url`, `audio_url`, or `pdf_url` is provided. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_4opt | IMAGE | The URLs of the images to use for image-to-image generation or image editing. Optional when at least one of `video_url`, `audio_url`, or `pdf_url` is provided. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_5opt | IMAGE | The URLs of the images to use for image-to-image generation or image editing. Optional when at least one of `video_url`, `audio_url`, or `pdf_url` is provided. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| image_6opt | IMAGE | The URLs of the images to use for image-to-image generation or image editing. Optional when at least one of `video_url`, `audio_url`, or `pdf_url` is provided. Each socket may carry a batch; they are sent in socket order (the first picture of socket 1 is number 1). | |
| videoopt | VIDEO | Optional video to use as input context. Accepts an http(s)/data URL to a video file (downloaded and sent inline, max 15MB) or a YouTube URL (passed through to the model without downloading). | |
| audioopt | AUDIO | Optional audio file to use as input context. Accepts an http(s)/data URL (downloaded and sent inline, max 15MB). | |
| 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. |
