ChatGPT vs Claude vs Gemini: do prompts need to be different?

By LLM Prompt Gen · Jul 28, 2026 · 1 min read

Short answer: mostly the same, with tweaks

A well-structured prompt works across ChatGPT, Claude and Gemini. But each model has preferences.

  • Claude likes clear XML-style tags and step-by-step reasoning.
  • ChatGPT works well with a system/role framing and markdown.
  • Gemini is strong with concise, explicit instructions.

One prompt, any model

Rather than rewriting for each, keep a solid structure (Role · Objective · Context · Format) and add a short model-specific note. Our engine can optimise the same brief for whichever model you target.
