Prompt sensitivity persists even with larger models, more few-shot examples, or instruction tuning — it is not solved by scaling alone

Summary

Even when you upgrade to a bigger model, add more example prompts, or fine-tune with explicit instructions, the output can still shift unpredictably based on how you word the request. This means system designers can't count on "just use a larger model" to make behavior stable; they need to build their own safeguards like prompt normalization, output validation, or redundancy at the system layer.

Dependents

These beliefs depend on this one:

IN prompt-sensitivity-is-fundamental-not-solvable-by-scale — LLM performance sensitivity to prompt formatting (40%+ accuracy shifts from reordering, 76-point swings from format changes) persists across model sizes, few-shot counts, and instruction tuning — it is an intrinsic property, not a fixable deficiency.
