  }
}

WebP Output — Generate an image in WebP format for smaller file size

const response = await env.AI.run(
  'openai/gpt-image-2',
  {
    prompt:
      'A neon-lit cyberpunk cityscape at night with rain-slicked streets and holographic billboards',
    quality: 'high',
    output_format: 'webp',

  {
    gateway: { id: 'default' },
  }
)
console.log(response)

Output

  }
}

Image Edit — Edit an existing image by providing it in the images array as base64 (a raw string or a data:image/{png|jpeg|webp};base64,... URI). This routes the call to OpenAI's /v1/images/edits endpoint. The example uses a tiny 32x32 smiley-face PNG - real inputs are the full base64 encoding of your source image.

const response = await env.AI.run(
  'openai/gpt-image-2',
  {
    prompt:
      'Transform this cartoon smiley into a photorealistic 3D clay sculpture sitting on a marble pedestal, studio lighting',
    images: [
      'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAYAAABzenr0AAAAnklEQVR42u2XQRLAIAgD8/839i/26qFCACm0ozPe1KwcQsAoXvgcAABxpwFowl4QWITHxW0LCBhxVngF4gKIirMQyBRnIJAtrkE8AuwWnyFEgKzfS1UA+3sWTju3BGAu7gKYIfBW+Q/AAQgBeMCkt1wVsLZjcwUYG2Z9wGLHZitWk1DEisubUYt2XB5IWkSyFqG0RSxvMZi0Gc1+Ox3fm00ZJ5mGVtkAAAAASUVORK5CYII=',
    ],
  },
  {
    gateway: { id: 'default' },
  }
)
console.log(response)

Output
Raw response

  },
  "gatewayMetadata": {
    "keySource": "Unified"
  }
}

Multi-Image Edit — Compose multiple input images by passing up to 16 base64 strings in the images array. The model blends the references; useful for combining subjects, styles, or reference shots. The example pairs a smiley-face PNG with a red ball PNG.

const response = await env.AI.run(
  'openai/gpt-image-2',
  {
    prompt:
      'Combine these into a single photorealistic scene: a ceramic smiley-face mug next to a red rubber ball on a sunlit wooden table',
    images: [
      'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAYAAABzenr0AAAAnklEQVR42u2XQRLAIAgD8/839i/26qFCACm0ozPe1KwcQsAoXvgcAABxpwFowl4QWITHxW0LCBhxVngF4gKIirMQyBRnIJAtrkE8AuwWnyFEgKzfS1UA+3sWTju3BGAu7gKYIfBW+Q/AAQgBeMCkt1wVsLZjcwUYG2Z9wGLHZitWk1DEisubUYt2XB5IWkSyFqG0RSxvMZi0Gc1+Ox3fm00ZJ5mGVtkAAAAASUVORK5CYII=',
