Two themes collide today: scale and efficiency. One user burned 14M tokens in five hours via Opus orchestrating 451 Sonnet subagents, while a community tool claims to cut token waste by 70%. Both reactions are rational. When you have unlimited headroom, you optimize for throughput. When you are rate-limited on Pro, you optimize for frugality. The meta-pattern: Claude's capability ceiling is now so high that the bottleneck is purely your budget tier, not the model itself. Plan accordingly.
