UnverifiedReasoning models may consume several times or even more than ten times the output tokens, directly driving up API call costs.78% similarUnverifiedTwo models with similar intelligence scores may differ in inference cost by several times or even an order of magnitude.76% similarUnverifiedEvaluating the per-task cost of large models requires considering both the token unit price and the number of tokens consumed to complete the task; the output token consumption of chain-of-thought reasoning models may increase by several times or even dozens of times.76% similarVerifiedIndustry estimates suggest that the inference cost of mainstream frontier models is approximately several times to tens of times the training cost.75% similarUnverified在反向模式下，当模型参数数量高达数百万时，计算梯度的成本仅与一次前向计算相当75% similar
