Image generation

The Image generation controller lets you create images based on text descriptions. This empowers developers to dynamically produce visuals for various applications.

Supported Providers

Intellinode supports image generation with the following providers: openai, stability.

Parameters

Specify the following parameters when initiating an image generation controller:

• provider: Identifier for the chosen AI service provider ('openai' for gpt-image-2, 'stability' for Stable Diffusion).
• apiKey: Your API key for accessing the selected provider's services.
• prompt: The text description based on which the image will be generated.
• model: The specific model variant to use.
• numberOfImages: How many different images to generate.
• width and height: Dimensions of the generated images.

Example

Import

const { RemoteImageModel, ImageModelInput } = require('intellinode');

Generate an image using stable diffusion.

const stabilityKey = 'your_stability_api_key';

async function generateImageWithStability() {
    const prompt = "A landscape of a futuristic city at sunset";

    try {
        const imageGenerator = new RemoteImageModel(stabilityKey, "stability");
        const images = await imageGenerator.generateImages(new ImageModelInput({
          prompt: prompt,
          numberOfImages: 1,
          width: 512,
          height: 512
        }));

        console.log("Generated Images:", images);
    } catch (error) {
        console.error("Image generation failed:", error);
    }
}

generateImageWithStability();

Generate an image using OpenAI gpt-image-2, the default OpenAI image model.

const openaiKey = 'your_openai_api_key';

async function generateImageWithOpenAI() {
    const prompt = "A photorealistic painting of an astronaut riding a horse in space";

    try {
        const imageGenerator = new RemoteImageModel(openaiKey, "openai");
        const images = await imageGenerator.generateImages(new ImageModelInput({
          prompt,
          model: 'gpt-image-2',
          numberOfImages: 1
        }));

        console.log("Generated Images:", images);
    } catch (error) {
        console.error("Image generation failed:", error);
    }
}

generateImageWithOpenAI();

The gpt-image models return base64 images; save one with fs.writeFileSync('image.png', Buffer.from(images[0], 'base64')).
