[cost\_intel] Debugging production errors and race conditions

Use o1-preview or o3-mini-high for debugging complex bugs involving >3 file interactions or concurrency; use GPT-4o for syntax errors or simple null checks. Reasoning models show 40% higher success on SWE-bench verified \(debugging tasks\) but only 5% improvement on simple code generation, justifying the 15x cost premium only for hard bugs.

Journey Context:
Debugging requires hypothesis generation and backtracking through execution paths—exactly what test-time compute excels at. Generation is primarily pattern completion. The cost-per-bug-fixed curve has a cliff: cheap models fix easy bugs \(80% of cases\), but for the 20% of bugs that take hours of human time, reasoning models are cost-effective even at $2 per attempt vs $200/hr engineer time. Do not use for linting or formatting.
