What you'll see in this lesson
- The map: which model for each job
No model is best at everything: each one shines at something, and choosing well saves hours of redoing images.
- Nano Banana 2.1: Google's all-rounder
It's the image model Google recommends by default: it generates in 1K, 2K or 4K, reasons before drawing and edits turn by turn.
- gpt-image-2 and OpenAI's new 2.5 family
Since September 2026 OpenAI offers gpt-image-2.5 in two versions: Flare, the fast one, and Sunburst, the most precise at editing.
- FLUX, Seedream and Qwen-Image: more options
For catalogs, for working locally or for text in other alphabets, these three complete the map.
- Readable text inside the image
Today's models write short headlines well if you give them the exact text, the position and the typeface.
- How to write an image prompt
Describe the image as you'd brief a photographer: shot type, subject, scene, lighting, camera and format.
- Editing photos and using reference images
The most useful thing for a business isn't inventing from scratch, but starting from your real photos and changing only what's needed.
- Usage rights: what you must check
Before publishing, check three things: who owns the references, whether a real person appears and what the model's license allows.
- Summary
Choose the model per job, write the prompt like a brief and check rights and text before publishing.
