Do I need an API key?

Yes. You need an OpenAI API key (with DALL-E access). Your key is stored only in your browser and never saved on our servers.

What image sizes are supported?

You can generate images in various sizes including square (1024×1024), wide (1792×1024), and tall (1024×1792).

How long does image generation take?

Image generation typically takes 10-30 seconds depending on the model and your internet connection.

AI Image Generator (API Key) Guide

Generate images from text descriptions using AI. Simply describe what you want to see and the AI creates it. Follow these steps: 1. Enter your OpenAI API key with DALL-E access. 2. Write a detailed description of the image you want to create. 3. Select image size: square (1024×1024), wide (1792×1024), or tall (1024×1792). 4. Choose how many images to generate (1-4). 5. Click generate and wait 10-30 seconds for your images. Tips: Include style keywords like "photorealistic", "oil painting", or "3D render". Specify lighting, composition, and mood for better results. Each generation uses API credits from your OpenAI account. Your prompt is tokenized and passed through a text encoder that maps words into a high-dimensional embedding space. A diffusion model starts from random noise and repeatedly denoises it, guided by that embedding, until a coherent image emerges. Style keywords steer the model toward photorealistic, painterly, or anime aesthetics, while negative prompts suppress unwanted elements. Each generation samples new random noise, which is why two runs of the same prompt produce different images.
