[cost\_intel] When does o1-mini beat o1-pro on code generation tasks?

Use o1-mini for well-structured algorithmic problems with deterministic test suites \(e.g., competitive programming\); reserve o1-pro for ambiguous architectural decisions or poorly specified requirements.

Journey Context:
Counter-intuitively, o1-mini often matches or beats o1-pro on LeetCode-style problems because the reasoning path is straightforward and the smaller model's lower latency allows more iterations in a fixed budget. However, o1-pro excels at 'fuzzy' coding tasks where the spec is incomplete. The mistake is assuming 'pro' is universally better—it's worse for deterministic algorithmic tasks due to overthinking and higher latency.
