Regarding 2.5 Pro Preview API Pricing: 1. to calculate my total charge, please confirm: candidates\_token\_count INCLUDES thoughts\_token\_count and I multiply it by the OUTPUT token rate. Then, I add prompt\_token\_count multiplied by the INPUT token rate. 2. how to configure the amount of thinking via the (Python) API? Many thanks, Elias ---

Hi @Ilias_Efstathiou Apologies for late response You’re mostly correct. Total Charge Calculation: ( candidates\_token\_count ) \* OUTPUT token rate (both the final output and the thinking tokens)+ (prompt\_token\_count ) \* INPUT token rate (initial input to the model). it’s important to note that thinkingBudget is currently only fully supported for Gemini 2.5 Flash, not Gemini 2.5 Pro.
