What is AI Image Generation?

An AI image generator uses artificial intelligence to create new images from text descriptions. This generative AI technology, also called text-to-image generation, allows anyone to produce photorealistic photos, anime illustrations, watercolor paintings, and countless other artistic styles simply by writing a text prompt. Whether you need quality images for social media, product mockups for commercial use, or eye-catching art for creative projects, AI-powered image tools have revolutionized how we create visual content.

Modern AI models like Nano Banana Pro, GPT from OpenAI, and Seedream have made it possible to generate high-resolution images that rival professional photography. These text-to-image generators understand natural language, so you can describe exactly what you want and fine-tune the output until it matches your vision. The best part? You don't need any design skills to create masterpieces.

This guide will teach you how to use AI image generators effectively. We'll cover text-to-image basics, explore different artistic styles, show you how to edit images with AI, and walk through practical use cases. For a detailed comparison of all available AI models, check our best AI image generators guide.

Text to Image: Creating Pictures from Prompts

The foundation of AI image generation is the text prompt. A well-written text description tells the AI exactly what to create. The more specific your image prompts, the better your results. Include details about subject, style, lighting, colors, and composition to get higher quality output.

Here are examples of AI-generated images created with different prompts. Click any image to see the full prompt and tweak it for your own creations:

Writing Better Prompts for Better Results

  • Be specific: Instead of "a dog," try "golden retriever puppy playing in autumn leaves, soft morning light"
  • Include art style: Add "watercolor," "oil painting," "anime," or "photorealistic" to guide the aesthetic
  • Specify quality: Terms like "high-resolution," "4K," "professional" help produce quality images
  • Set the aspect ratio: Choose portrait (2:3), landscape (16:9), or square (1:1) based on your needs

Exploring Artistic Styles

One of the most powerful features of AI art generators is their ability to create images in any art style imaginable. From classical oil paintings to modern anime, from watercolor illustrations to photorealistic renders, you can specify exactly the aesthetic you want. This makes AI tools perfect for creating everything from book covers to character designs. For more on creating AI art, see our best AI art generator guide.

Pro Tips for Creating Quality Images

1. Start with a Template, Then Fine-Tune

Don't try to perfect your image in one generation. Start with a basic prompt, see what the AI produces, then tweak your text description based on the output. This iterative approach leads to better results than trying to write the perfect prompt upfront.

2. Use Reference Images When Possible

Many AI image generators accept reference images. Upload an image you like and ask the AI to create something similar, or use it as a starting point for style transfer. This gives you much more control over the final output.

3. Specify Aspect Ratio for Your Use Case

Always set the correct aspect ratio before generating. Instagram posts work best at 1:1, Pinterest pins at 2:3, YouTube thumbnails at 16:9. Generating at the target dimensions produces higher quality than cropping later.

4. Combine AI Tools for Complete Workflows

Use a logo generator for branding, then create matching social media templates. Generate product photos, then animate them into video with AI video tools. The most powerful workflows combine multiple AI capabilities.

5. Understand Pricing and Credits

Different models have different credit costs. Flux Schnell is cheapest for quick iterations, while Nano Banana Pro costs more but produces higher quality. Use fast models for brainstorming, then switch to premium models for final output.
