How does prompt engineering differ across AI models?
Models vary in verbosity, safety behavior, and sensitivity to examples. Some need explicit structure to avoid rambling; others respond better to conversational framing. Small models may require tighter constraints and more examples; larger ones can infer more from fewer words but may need guardrails. Porting prompts is a starting point, not a drop-in replacement. Always test across a fixed dataset and calibrate style, refusals, and formatting.
In practice
Write a model-agnostic ‘spec prompt’ first, then tailor per model with the smallest changes possible.
Where to start
- [01]Run the same 20-case eval across 2–3 models.
- [02]Record where each model fails and why.
- [03]Create per-model overlays (extra rules/examples).
- [04]Re-test monthly; models evolve.
