Model Prompting Comparisons

How does prompting Claude differ from prompting GPT-4o? When does a Qwen prompt fall flat on Mistral? These pages walk through the subjective differences in how each model expects to be prompted — format, idioms, what to over-explain, what to leave out.

Subjective comparisons based on each model's official documentation — not a head-to-head benchmark. For empirical numbers see /research.

Claude Sonnet 4.6 vs GPT-4o
AnthropicvsOpenAI

Claude uses XML structuring for precise instruction following, while GPT-4o relies on grounding rules and reasoning hints for complex tasks.
