[pkg]: bing-create

Generate images using Bing Image Creator's internal API. Supports DALL-E 3, GPT-4o, and MAI-Image-1 models.

npm install bing-create

Basic usage

The package exports a single function that generates images from text prompts. You need the _U cookie from an authenticated Microsoft account to use the API. Sign in at bing.com/images/create, open DevTools (F12), go to Application ⇢ Cookies ⇢ https://www.bing.com, and copy the _U cookie value.

import { createImages } from "bing-create";

const images = await createImages("a cat wearing a space helmet", {
  cookie: process.env.BING_COOKIE ?? "",
});

for (const { url, suggestedFilename } of images) {
  console.log(url);
  console.log(suggestedFilename);
}

The function returns an array of results with URLs and suggested filenames. Authentication errors indicate the cookie expired. Cookies typically last several days.

Models and aspect ratios

Three models are available with different performance characteristics:

Model	Images	Speed	Aspect ratios
DALL-E 3	4	~5-15s	square, 7:4, 4:7
MAI-Image-1	1	~20-30s	square, 3:2, 2:3
GPT-4o	1	~30-70s	square, 3:2, 2:3

DALL-E 3 is the default model. All models support their listed aspect ratios. Actual pixel dimensions vary by model and are documented in CONTRIBUTING.md.

await createImages("mountain sunset", {
  cookie: process.env.BING_COOKIE ?? "",
  model: "gpt4o",
  aspectRatio: "landscape",
});

Configuration

The createImages function accepts a prompt string and an options object. The cookie field is required. All other fields are optional:

await createImages(prompt, {
  cookie: string,           // required: _U cookie value
  model: "dalle3",          // optional: dalle3 | gpt4o | mai
  aspectRatio: "square",    // optional: square | landscape | portrait
  timeouts: {
    generationMs: 300_000,   // optional: total generation timeout
    pollingMs: 1_000,        // optional: poll interval
    requestMs: 30_000,       // optional: per-request timeout
  },
});

Timeouts control generation behavior. The generation timeout sets the maximum wait time for image creation. Polling interval determines how often to check for completion. Request timeout applies to individual HTTP requests.

See CONTRIBUTING.md for error scenarios and implementation details.
