A note on image generation: Nano Banana vs DALL-E
The image tools deserve their own note, because this is where the two feel most different. Google's image model, nicknamed Nano Banana, got popular because it edits an existing photo cleanly and keeps the same character looking consistent across many images. ChatGPT makes images with its own built-in model (and DALL-E), and it is especially good at rendering readable text inside a picture and following a long, exact brief. Neither is strictly better. For touching up a real photo or holding a character steady, try Gemini. For a poster with clean text or a very specific instruction, try ChatGPT. We keep free prompt libraries for both so you start from something that already works instead of a blank box.
