[cost\_intel] Using GPT-4o-mini for complex architectural refactoring across multiple files

Reserve GPT-4o/Claude 3.5 Sonnet for tasks requiring >3 file coordination, novel design patterns, or debugging race conditions. Cheaper models drop to 60% accuracy on multi-hop reasoning across context windows.

Journey Context:
Small models excel at isolated functions but fail on context window coherence across files. The hidden cost is debugging time from partial refactors. Threshold: >200 lines of context or >2 files with dependencies. Cost of GPT-4o is $5/1M vs mini at $0.60/1M, but failed refactors cost hours.
