[cost\_intel] Selecting between o1 and GPT-4o for software engineering tasks

Use o1 for competitive programming \(Codeforces Div 2\+\) and complex algorithmic design; use GPT-4o for API integration, CRUD generation, and refactoring existing codebases

Journey Context:
On Codeforces, o1 achieves ~1800 Elo equivalent while GPT-4o performs at ~800 Elo, making o1 essential for hard algorithmic problems. However, for typical production tasks like 'generate a React form component' or 'add OAuth to Flask app', GPT-4o achieves 80% accuracy with sub-2s latency vs o1's 30s\+ latency and only 85% accuracy. The cost differential \(30-50x\) makes o1 prohibitive for boilerplate where pattern matching suffices over deep reasoning.
