+Fast preset updatedThe Agent API fast preset now uses openai/gpt-5.6-luna with minimal reasoning effort and priority processing. Dynamic fast preset requests pick up the change automatically. If you use a frozen configuration, update the model and reasoning effort and set service_tier to priority. Priority processing uses 2× the model’s standard token prices.
