[cost\_intel] Over-paying for reasoning models on simple code generation

Use o1 only for >50 line algorithms, complex concurrency, or novel data structures. Use Claude 3.5 Sonnet or GPT-4o for CRUD APIs, React components, regex. Break-even is distributed systems complexity.

Journey Context:
Reasoning models excel at 'think twice' coding—edge cases, thread safety—but over-engineer simple scripts. Cost: $15/million tokens versus $0.50/million. Signature of waste: Using o1 to write a Python script wrapping an API call. Complex tasks $compilers, distributed systems$ show 40%\+ improvement; simple tasks show 0% improvement at 30x cost.
