- Cursor says a frontier model can act as the planner and orchestrator, while a cheaper model does the bulk of the execution.
- In its SQLite rebuild experiment, the team reported a 15x cost difference depending on model mix.
- The takeaway: most tokens in complex agentic work do not need frontier intelligence; reserve it for decomposition, design decisions, and tricky trade-offs.
