API call fees are priced separately for input tokens and output tokens, and the unit price of output tokens is typically higher than that of input tokens, because the output stage requires autoregressive inference.

UnverifiedCompared to lower reasoning levels, the difference in API costs between reasoning levels for high reasoning settings can reach several times the cost.77% similarUnverified大模型API计费通常按输入和输出token分别计价，不同模型单价差异可达百倍76% similarUnverifiedOutput token pricing is typically 2–4 times that of input tokens, because the generation process requires step-by-step decoding and computation of attention weights.75% similarVerifiedThe price of output tokens for large language models is typically 4–8 times that of input tokens, because output involves autoregressive generation requiring multiple forward passes, resulting in higher marginal costs.75% similarUnverifiedOutput tokens are typically more expensive than input tokens because outputs require autoregressive token-by-token generation, which has higher computational intensity and lower GPU utilization.73% similar
