Claude Code 后台子智能体改用 Haiku 5.5 写状态行
Background subagents in Claude Code now use less of your usage limit.
AI 导读
Claude Code 的后台子智能体每 30 秒更新一次状态行，过去每次更新都要重读整段对话。现在改由 Haiku 5.5 根据简短笔记生成状态行，每次更新成本降低约 99%，子智能体本身仍使用自己的模型。含后台子智能体的会话用量减少约 5%，同一额度约可多跑 6% 的提示词；该功能已向多数 Pro、Max、Ultra 用户及全部 Team、Enterprise 用户开放，需升级到 v2.1.316+。

Background subagents in Claude Code now use less of your usage limit.
A running subagent updates its status line every 30 seconds, and each update used to re-read its whole conversation. Now Haiku 5.5 writes it from short notes instead, so each update costs about 99% less. https://t.co/u4maCuWq6A
