[cost\_intel] Using o1-preview for simple CRUD API endpoints or boilerplate generation

Use GPT-4o-mini for CRUD and boilerplate \(20x cheaper\); reserve reasoning models for concurrency, distributed systems, or security-critical code with >3 interacting state variables

Journey Context:
The cost-per-line is 20x higher with reasoning models, but for race conditions and deadlock prevention, instruct models hallucinate fixes that create deadlocks or use incorrect locking primitives. The quality cliff appears when state transitions involve more than three variables or cross-process boundaries. For simple CRUD, reasoning models over-optimize and generate unnecessary abstractions.
