[cost\_intel] Using cheaper code models for cross-file refactoring requiring architectural consistency

Reserve Sonnet 3.5 or o1 for code tasks requiring novel design patterns or cross-file refactoring >5 files; cheaper models produce locally correct but architecturally inconsistent code requiring costly rework

Journey Context:
Cheap models \(CodeLlama, GPT-4o-mini\) excel at single-function generation but lack context window coherence for systemic changes. They duplicate logic, break DRY, or create circular dependencies across files. Sonnet maintains architectural intent across 10k\+ token contexts, reducing integration bugs by 60% on SWE-bench verified.
