Effective prompting strategies are model-specific — a technique that works on one model may degrade performance on another, and techniques do not reliably transfer across models or even across minor prompt reformulations

Summary

You can't treat prompt engineering as a universal recipe: a phrasing tweak that improves output on one model can quietly make another model worse, and even small rewordings of the same prompt can shift results unpredictably. This means any system relying on prompts needs to validate them per-model and per-variant rather than assuming a winning strategy transfers cleanly.

Dependents

These beliefs depend on this one:

IN prompt-optimization-is-paradoxically-automatable-yet-fragile — Prompt engineering is paradoxically both automatable (LLMs generate prompts at human-level quality) and deeply fragile (model-specific, with 40%+ accuracy shifts from minor formatting changes), implying that prompt optimization must be continuous, model-specific, and potentially self-maintaining rather than a one-time engineering effort.
