Running all agent calls including subagents on the most capable (and expensive) model

✅ What Claude Opus (monolithic routing) does well

  • Consistent capability
  • Simpler architecture
  • No routing logic needed

❌ Limitations for Agents

  • High token costs
  • Inefficient for narrow-scope tasks
  • Wastes capability on simple operations
  • Busts cache on every call

Why AI Agents are replacing Claude Opus (monolithic routing)

Intelligent routing gateways like Rayline route subagent calls to cheaper models (Sonnet, Haiku, open models) based on task scope, reducing costs 60-90% while preserving main agent capability
