AI image generation has evolved rapidly. Today's models can produce photorealistic images, digital art, and creative illustrations from simple text descriptions. This guide covers everything you need to know to get started.
What is AI Image Generation?
AI image generation (text-to-image) uses deep learning models to create images from text prompts. You describe what you want, and the AI produces a matching image in seconds.

How to Write Effective Prompts
Good prompts are the key to great AI images. Here are some tips:
- Be specific — Instead of "a cat", try "a fluffy orange tabby cat sitting on a windowsill at sunset"
- Include style keywords — "oil painting style", "photorealistic", "anime style", "watercolor"
- Describe lighting — "soft golden hour light", "dramatic studio lighting", "neon glow"
- Mention composition — "close-up portrait", "wide angle landscape", "bird's eye view"
- Add quality modifiers — "highly detailed", "8K resolution", "professional photography"
