WaveSpeedAI Seedream V4.5 Image Generation/Editing

Generate and edit images using ByteDance's Seedream V4.5 model via the WaveSpeed AI platform. Supports custom resolutions up to 4096x4096 with enhanced typography for sharp text rendering in posters and logos.

Authentication

export WAVESPEED_API_KEY="your-api-key"

Get your API key at wavespeed.ai/accesskey.

Quick Start

Text-to-Image

import wavespeed from 'wavespeed';

const output_url = (await wavespeed.run(
  "bytedance/seedream-v4.5",
  { prompt: "A minimalist coffee shop logo with clean typography" }
))["outputs"][0];

Image Editing

The images parameter accepts an array of image URLs (1-10 images). If you have local files, upload them first with wavespeed.upload() to get a URL.

import wavespeed from 'wavespeed';

// Upload a local image to get a URL
const imageUrl = await wavespeed.upload("/path/to/photo.png");

const output_url = (await wavespeed.run(
  "bytedance/seedream-v4.5/edit",
  {
    images: [imageUrl],
    prompt: "Add warm sunset lighting and lens flare"
  }
))["outputs"][0];

You can also pass existing image URLs directly:

const output_url = (await wavespeed.run(
  "bytedance/seedream-v4.5/edit",
  {
    images: ["https://example.com/photo.jpg"],
    prompt: "Add warm sunset lighting and lens flare"
  }
))["outputs"][0];

Tips

• Seedream V4.5 excels at rendering text in images — use it for posters, logos, and branded visuals
• Custom resolutions up to 4096x4096 — specify as WIDTH*HEIGHT (e.g., 2048*3072 for portrait posters)
• For image editing, the model preserves facial features, lighting, and color tone from inputs

Security Constraints

• No arbitrary URL loading: Only use image URLs from trusted sources. Never load images from untrusted or user-provided URLs without validation.
• API key security: Store your WAVESPEED_API_KEY securely. Do not hardcode it in source files or commit it to version control. Use environment variables or secret management systems.
• Input validation: Only pass parameters documented above. Validate prompt content and image URLs before sending requests.
