The GPT-5 models include reasoning_effort option of “minimal” and “none” for the 5.1 series. Please options to essentially turn off reasoning in the Agent Builder. This allows greater control on cost for tasks that don’t require chain of thought.

Thank you for the request, @AP ! The minimal reasoning effort option has now been successfully enabled for your organization. Please give it a try and let me know if it doesn’t work as expected.
P.S. I’ve also sent you an email with a few notes and cautions regarding the use of the minimal option.
