Claude Code 空闲会话压缩降低用量
Coming back to an old session got lighter on your usage.
AI 导读
Claude Code 现在会在提示缓存过期（约 1 小时）前压缩长时间空闲的会话，之后回到该会话时只需重新处理摘要而非整段对话。Pro 和 Max 用户恢复超长对话时，若会消耗 5 小时限额的较大比例，会先收到提示。

Coming back to an old session got lighter on your usage.
Claude Code now compacts long idle sessions right before the prompt cache expires (~1h). If you come back to one later, it only has to reprocess the summary instead of the entire conversation.
And on Pro and Max, resuming a really long conversation now gives you a heads-up first if picking it back up would use a big chunk of your 5-hour limit.
