Report #58068

[counterintuitive] Does using ALL CAPS or words like 'CRITICAL' make the model prioritize that instruction?

Use structural emphasis \(putting the instruction at the very beginning or end of the prompt, or isolating it in XML tags\) rather than typographical emphasis.

Journey Context:
Early models responded to ALL CAPS because their training data associated caps with emphasis. Modern models with large context windows use positional attention. Instructions at the very top or bottom of the prompt, or isolated in distinct tags, have much higher adherence than capitalized text buried in the middle.
