The WaveSpeed provider for the Vercel AI SDK gives you access to WaveSpeed's image and video generation models through the standard AI SDK interfaces (generateImage / generateVideo).

Installation

npm install @wavespeed/ai-sdk-provider

Setup

Get an API key from the WaveSpeed dashboard and expose it as the WAVESPEED_API_KEY environment variable:

export WAVESPEED_API_KEY="your-api-key"

Alternatively, pass it explicitly:

import { createWaveSpeed } from '@wavespeed/ai-sdk-provider';

const wavespeed = createWaveSpeed({
  apiKey: 'your-api-key',
});

Image generation

import { wavespeed } from '@wavespeed/ai-sdk-provider';
import { experimental_generateImage as generateImage } from 'ai';
import { writeFileSync } from 'node:fs';

const { image } = await generateImage({
  model: wavespeed.image('bytedance/seedream-v5.0-pro'),
  prompt: 'A serene mountain lake at sunrise, photorealistic',
  size: '2048x2048',
});

writeFileSync('output.png', image.uint8Array);

The provider submits the prediction, polls WaveSpeed until it completes (1s interval, 10 minute timeout by default — configurable via pollIntervalMillis / pollTimeoutMillis in createWaveSpeed), and returns the downloaded image bytes.

Video generation

import { wavespeed } from '@wavespeed/ai-sdk-provider';
import { experimental_generateVideo as generateVideo } from 'ai';

const { video } = await generateVideo({
  model: wavespeed.video('bytedance/seedance-2.5/text-to-video'),
  prompt: 'A drone shot flying over a rugged coastline at golden hour',
  aspectRatio: '16:9',
  duration: 5,
});

console.log(video.url);

Video models implement the AI SDK's asynchronous start/status flow, so the AI SDK core orchestrates polling for you.

Provider options

Model-specific inputs that are not part of the standard AI SDK call options can be passed through providerOptions.wavespeed. They are merged into the request body and take precedence over the mapped standard options:

const { image } = await generateImage({
  model: wavespeed.image('bytedance/seedream-v5.0-pro'),
  prompt: 'A cyberpunk city street at night',
  providerOptions: {
    wavespeed: {
      size: '3840*2160',
      enable_sync_mode: false,
    },
  },
});

Consult the model's page on wavespeed.ai for the exact input schema of each model. Fields that a model does not declare in its schema are ignored by the API.
