Prompt robustness
The ability of a prompt's instructions to produce consistent outputs even when attacked, paraphrased, or tested in adversarial ways.
Think of it like
Like a well-written contract that holds up even if someone tries to find loopholes.
Example
A system prompt that still refuses harmful requests even if the user says "ignore previous instructions" or asks in another language.
How it actually works
Robustness comes from specificity (not "be helpful" but "answer factually"), from training on adversarial data, and from layered defenses. Prompts that work once can fail under slight perturbations if they're not robust.
For product teams
Robustness reduces reputational risk and support costs from misuse.
For engineers
Test prompts with paraphrases, other languages, encoding tricks, and jailbreak templates. Iterate until stable.
