[cost\_intel] High cost of reasoning models for code generation not justified by accuracy gains

For standard code generation \(not complex algorithms\), use GPT-4o with temperature 0.3 and 3-attempt retry loop; it beats o1 on cost-per-correct-solution by 3-5x.

Journey Context:
Benchmarks show o1 excels at competition-level algorithms \(AIME, Codeforces\) but shows only 5-10% improvement on typical CRUD/API code versus GPT-4o. However, o1 costs 10-30x more and adds 10x latency. Common error: defaulting to o1 for all code tasks 'because it's smarter.' The cost-per-correct-answer curve flips at algorithmic complexity: use instruct models for boilerplate, reserve reasoning for complex debugging/architecture.
