[cost\_intel] When do reasoning models justify 10x cost for coding tasks?

Use o3/o1 for competitive programming \(Codeforces 1800\+\) and novel algorithm design; use GPT-4o for boilerplate CRUD. Signature: if pass@1 with 4o < 40%, switch to reasoning. Below this threshold, 4o-turbo actually beats o1-mini because reasoning overhead introduces 'overthinking' bugs in simple I/O tasks.

Journey Context:
People assume reasoning helps all coding. Actually, for boilerplate generation, 4o-turbo beats o1-mini because reasoning overhead introduces 'overthinking' bugs in simple I/O tasks. The cliff is at algorithmic complexity O\(n²\) optimization problems where explicit step-by-step logic beats pattern completion.
