Claude Tip: I’ve heard several people report that Fable 5.1 has been burning through their usage fast. Happened to me as well. Here’s what I’m doing now: /effort medium for everyday work/coding (equivalent perf to Fable 5 on high) and CLAUDE_CODE_SUBAGENT_MODEL=opus so subagents run on Opus. I save xhigh, max and Ultracode for the complex work jobs.
