Reasoning mode performs internal chain-of-thought reasoning before the final answer, and the thinking tokens generated are billed; in complex programming tasks, thinking tokens may account for 60%–70% of total consumption, and costs may be 3–5 times that of normal mode.

UnverifiedThe reasoning tokens produced by reasoning models share the same max_tokens budget as the final output, and they are billed as usual even if the visible reply is an empty string.78% similarUnverifiedThinking tokens are the tokens a reasoning model consumes for internal reasoning before producing an answer; they are usually not shown directly to the user but are still billed as output tokens.77% similarVerifiedReasoning budget refers to the upper limit on the number of intermediate reasoning tokens a chain-of-thought model is allowed to consume before generating a final answer; the higher the budget, the deeper the self-reflection and multi-step verification the model can perform.77% similarUnverifiedLarge models are billed by the number of input plus output Tokens for each inference.77% similarUnverifiedReasoning tokens are the internal thinking content the model generates before giving its final answer, usually billed at the output rate, and can account for an extremely high share of total Agent output (77% of the bill in the example).77% similar
