Opus 5.5 每输入输出 token 降价 20%，缓存读取便宜 60%
Anthropic 给 Opus 5.5 降了价，有人算好了在 Claude Code 里到底省多少钱，还做了个计算器，你可以套自己的用量算一算。
Opus 5.5 的输入和输出 token 价格比 Opus 5 下降 20%，缓存读取价格下降 60%。
ClaudeDevs 团队实际测算了这些价格变化对 Claude Code 中任务成本的影响，并发布了一个成本计算器。用户可以从 /usage 获取数据，代入计算器算出自己的实际开销变化。
Opus 5.5 is 20% cheaper per input and output token than Opus 5, and 60% cheaper on cache reads. So what does that actually do to the cost of a task in Claude Code?
We ran the numbers, and built a calculator so you can run yours from /usage:
