[cost\_intel] Which code generation tasks justify 10x cost of reasoning models over GPT-4o?

Use reasoning models only for algorithmic complexity >LeetCode Medium or cross-file dependencies >3 files; for boilerplate, CRUD, or single-function implementations, GPT-4o-family achieves 95% accuracy at 1/10th cost.

Journey Context:
Analysis of coding benchmarks shows reasoning models \(o1-preview\) achieve 85-90% on HumanEval\+ while GPT-4o achieves 75-80%, but at 10-30x cost per token. However, the gap widens on 'algorithmic complexity' \(graph algorithms, dynamic programming\) where o1 hits 80% vs GPT-4o 45%. Conversely, on 'boilerplate generation' \(React components, API routes\), the delta is <5% but cost remains 10x. Signature: If task requires >2 step reasoning chain or >100 line context window analysis, upgrade to reasoning.
