[cost\_intel] How to set reasoning\_effort/o1-mini thinking budget to avoid paying for overthinking on medium-complexity coding tasks?

Set reasoning\_effort='low' \(or thinking budget ~2k tokens\) for o1-mini on debugging tasks with <200 lines of code or single-file refactors; use 'medium' \(5k tokens\) only when debugging requires reasoning across >3 files or involves algorithmic optimization. 'High' is almost never cost-effective for coding versus using o1-preview.

Journey Context:
o1-mini charges for reasoning/thinking tokens \(hidden chain-of-thought\) which can balloon to 10k\+ tokens even on simple tasks if unconstrained. At $3/$12 per 1M tokens for o1-mini, a 10k thinking token burn costs $0.12 just in hidden reasoning—often exceeding the value of the output. 'Low' effort caps this at ~2k tokens, sufficient for most single-file debugging. People default to 'medium' assuming 'more thinking = better code,' but o1-mini hits diminishing returns quickly on localized tasks; extra tokens go into irrelevant theoretical exploration. Quality signature of too much budget: outputs contain philosophical asides about code beauty or over-engineered abstractions for simple scripts.
