For transformation tasks (extraction, standardization, format conversion, grammar fixes) prefer a temperature of 0 or up to 0.3. For writing tasks, you should juice the temperature higher, closer to 0.5. If you want GPT to be highly creative (for marketing or advertising copy for instance), consider values between 0.7 and 1.
