01 / Plain-language context

How Image Generation works.

Image generation models convert text prompts into images. The leading options: OpenAI's DALL-E 3 (integrated with GPT, good at following complex prompts), Google's Imagen 3 (high quality, cost-effective via Gemini API), Stability AI's Stable Diffusion (open source, self-hostable), and Midjourney (highest aesthetic quality, Discord-based). Pricing ranges from $0.02-0.08 per image depending on provider and resolution.

For builders, the key decision is which provider to use. Imagen via Gemini API offers the best cost-to-quality ratio for most applications. DALL-E 3 integrates seamlessly if you are already using OpenAI. Stable Diffusion is free to self-host but requires GPU infrastructure. Each has different content policies and style strengths.

Common integration patterns: (1) Direct generation from user prompts (art tools, design apps), (2) AI-enhanced prompts (user gives a simple description, your app expands it into a detailed prompt), (3) Programmatic generation (thumbnails, marketing images, product mockups generated in batch). Always implement content moderation for user-facing generation features.
