Prompt instructions

ProductAudience

Give me a filled-in prompt that follows this guide, plus the one thing to check in the result, for a short video about [your product], for [your audience]. The technique is which model for stills: picks the image model by the job instead of by the hype of the week. How it works: nano Banana Pro by default; Nano Banana 2 for cheap test rounds; GPT Image 2.5 when the image carries text or a layout. It is right for: before writing any image prompt. A tutorial's model advice is an argument, not a rule: tutorials three weeks apart named different best models for skin. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing.

The same prompt works in Claude, ChatGPT and Gemini.

Watch out

A tutorial's model advice is an argument, not a rule: tutorials three weeks apart named different best models for skin. Compare with one image before switching.measured: Director Chair field notes on image prompting

Test rounds before the final	Nano Banana 2	close to Pro for a fraction of the cost
Text, interface, typography on the image	GPT Image 2.5	positioned for design and text
Character sheets, a second opinion	Seedream 5	one tutorial's pick, not measured by us
