This is an n8n community node for WaveSpeed AI - generate images and videos with hundreds of hosted AI models (Seedream, Nano Banana, GPT Image, Seedance, Wan, and more) directly from your n8n workflows.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation:

In n8n, go to Settings > Community Nodes.
Select Install.
Enter @wavespeed/n8n-nodes-wavespeed and confirm.

Credentials

Create a WaveSpeed account at wavespeed.ai.
Create an API key under Access Keys in your dashboard.
In n8n, create a new WaveSpeed API credential and paste the key.

The credential test calls GET /api/v3/balance, so a green check also confirms the key has API access.

Operations

All operations submit a prediction to POST https://api.wavespeed.ai/api/v3/{model} and poll GET /api/v3/predictions/{id}/result until it finishes. The output for each item is:

{
	"urls": ["https://..."],
	"outputs": ["https://..."],
	"id": "<prediction id>",
	"model": "<model id>",
	"timings": { "executionTime": 1234 }
}

Generate Image

Generate an image from a text prompt.

Model - WaveSpeed model ID (default bytedance/seedream-v5.0-pro).
Prompt - text description of the image.
Image Options - optional Resolution (1k / 1.5k / 2k), Aspect Ratio, and Additional Inputs (JSON) merged into the request body. Anything else the model accepts (for example output_format) goes in Additional Inputs.

Generate Video

Generate a video from a text prompt.

Model - WaveSpeed model ID (default bytedance/seedance-2.5/text-to-video).
Prompt - text description of the video.
Video Options - optional Duration (Seconds) and Additional Inputs (JSON).

Run Model

The power operation: run any of the models on wavespeed.ai/models by passing the model ID and the full request body as JSON. Use this for image-to-image, image-to-video, LoRA, upscaling, lipsync - anything the platform hosts.

Shared options

Download Output - download the generated files and attach them as n8n binary data (data, data_1, ...), ready for the next node (upload to S3, send via Slack, etc.).
Poll Interval (Seconds) - how often to check progress (default 2).
Timeout (Seconds) - how long to wait before the node fails (default 600). The prediction keeps running server-side even if the node times out; the error message includes the task ID.

Transient poll failures (network errors, HTTP 429 and 5xx) are retried automatically up to 5 times per poll, so one unlucky request never kills a running generation. Client errors (4xx) fail fast.

Do not enable "Retry On Fail"

Leave n8n's node-level Settings > Retry On Fail switched off for generation operations. n8n retries by re-running the whole node, which submits a new, separately billed prediction instead of resuming the existing one. The node already retries the parts that are safe to retry (result polling) internally. If you need the task ID of a failed item, enable Continue On Fail instead - the error row carries id and the message names the task.

Example workflow

A minimal prompt-to-image workflow you can paste into n8n (Workflow > Import from Clipboard):

{
	"nodes": [
		{
			"parameters": {},
			"name": "When clicking \"Execute Workflow\"",
			"type": "n8n-nodes-base.manualTrigger",
			"typeVersion": 1,
			"position": [0, 0]
		},
		{
			"parameters": {
				"operation": "generateImage",
				"model": "bytedance/seedream-v5.0-pro",
				"prompt": "A lighthouse on a cliff at dawn, cinematic lighting",
				"imageOptions": {
					"size": "2048*2048"
				},
				"options": {
					"downloadOutput": true

			},
			"name": "WaveSpeed",

	],
	"connections": {
