[cost\_intel] Assuming reasoning models always improve code generation accuracy

Use o1/o3 for algorithmic logic, complex debugging, and architectural planning; use gpt-4o for boilerplate generation, CRUD APIs, and standard framework patterns \(React, FastAPI\).

Journey Context:
On HumanEval and SWE-bench, reasoning models show 20-30% improvement on hard algorithmic problems \(dynamic programming, concurrency bugs\) but only 0-5% gains on standard boilerplate generation. Reasoning models sometimes over-engineer simple tasks, adding unnecessary abstractions due to 'planning overkill.' Latency constraints also prevent iterative coding flows \(autocomplete, lint-fix cycles\). The cost-per-correct-line is 50x higher for simple CRUD endpoints. Sweet spot: Use o1 for 'debug why this race condition happens' or 'design this distributed transaction flow' but not 'generate a FastAPI endpoint from this SQL schema.' Validate with internal benchmarks on your specific codebase.
