Subagent-heavy workflows burn roughly 7x the tokens of a single thread because each agent re-reads context in a fresh window. Keep the planner and reviewer on Opus, run worker subagents on Haiku (5x cheaper) or Sonnet, and push heavy context-reading down into the workers. Practitioners report 40-70% savings on focused tasks, with the biggest wins when a context-mode subagent absorbs heavy MCP tool use (source).
