Consistency and variation.
WHY IT HAPPENS
Responses are generated with deliberate variation. The same question produces different wording.
WHY THIS IS INTENTIONAL
Completely deterministic output is repetitive and generally worse for writing tasks.
WHAT IT MEANS FOR YOU
You cannot rely on identical output from identical input Regenerating is a legitimate technique when an answer is poor A good result may not be exactly reproducible
WHEN VARIATION IS A PROBLEM
Extracting structured data Anything another system will process Work several people must produce consistently
HOW TO REDUCE IT
Specify the format precisely Give an example of the exact output you want Use the identical prompt each time
HOW TO USE IT
Generate several versions and pick the best.
Regenerate when the first attempt misses. That costs nothing.
THE PRACTICAL HABIT
If an answer seems poor, try again before concluding it cannot do the task.
