一位 Claude 用户为改善 token 用量，改用 Opus 做规划、按任务难度分配不同模型，结果收到提示：82% 的用量来自 subagent 密集的会话，因为每个 subagent 都会发起自己的请求。他感觉 subagent 比主对话更耗 token，但因使用更便宜的模型而认为影响不大，于是发帖询问自己的做法是否正确。

I'm trying to improve my token usage and the quality of my work with Claude. I stopped having long sessions with Opus and open new sessions for different topics, or passing info with md files.

Then I started asking Opus to do plans and divide the tasks, assigning different models according to difficulty.

Now when i check usage i have this warning:

82% of your usage came from subagent-heavy sessionsEach subagent runs its own requests. Be deliberate about spawning them — and consider configuring a cheaper model for simpler subagents.

Which is what I am doing already.

I haven't properly tested, but i also have the impression that these subagents use more tokens that what the main conversation would, but since it's cheaper models it shouldnt matter.

Am I doing this correctly? Whats your approach?
