## AI 摘要

OpenAI 将 GPT-5.5 的官方定价较 GPT-5.4 提高了一倍，声称更短的响应能抵消成本上涨。但 OpenRouter 对实际使用数据的分析显示，真实成本涨幅在 49% 到 92% 之间，具体取决于输入长度。与此同时，Anthropic 也提高了其 Opus 4.7 模型的价格。由于两家公司都在考虑首次公开募股，这一涨价趋势可能将持续。

GPT-5.5 costs 49 to 92 percent more than its predecessor, depending on the input length

GPT-5.5's list price has doubled compared to GPT-5.4. Input tokens now cost $5 and output tokens $30 per million, up from $2.50 and $15. OpenAI says shorter responses should partially offset this, but a study by OpenRouter shows real-world costs still rose 49 to 92 percent.

For inputs over 10,000 tokens, responses are 19 to 34 percent shorter, easing costs somewhat. In the 2,000 to 10,000 token range, however, responses run 52 percent longer. For short inputs under 2,000 tokens, response length barely changes, nearly doubling effective costs. The data comes from OpenRouter's usage logs from April 2026.

Input length Avg $/M tokens (5.4) Avg $/M tokens (5.5) Change < 2K tokens $4.89 $9.37 +92% 2K - 10K $2.25 $3.81 +69% 10K - 25K $1.42 $2.15 +51% 25K - 50K $1.02 $1.65 +62% 50K - 128K $0.74 $1.10 +49% 128K+ $0.71 $1.31 +85%

Artificial Analysis previously found only a 20 percent increase, though that study tested benchmarks, not real tasks. Anthropic followed a similar path, raising Opus 4.7 prices 30 to 40 percent due to higher token consumption. With both companies heading toward IPOs, prices are likely to keep climbing.
