Recursive 8-layer sub-agents burn quotas fast; Opus 5 efficiency review
nptacek · x · 2026-08-21
Key Observations
- Compute Sink: Instructing Opus to spawn 8 sub-agents, each spawning 8 more, consumes quotas at "warp speed".
- Efficiency Comparison: Compared to Fable, which often drifts into tangential tasks and wastes time, Opus 5 executes tasks efficiently and actually fixes bugs as requested.
Takeaway
For direct debugging tasks, a higher-tier model's direct execution is more reliable than broad multi-agent swarming.
