Report #83259

[cost\_intel] Debug latency for production incidents in microservices with >10k line codebases

Deploy o1 for root-cause analysis of distributed system failures; restrict GPT-4o to syntax errors or single-file refactoring

Journey Context:
Instruct models debug by pattern-matching against common errors in their training data. In large, idiosyncratic codebases with custom abstractions, this produces 'symptom fixing' \(masking null pointers\) rather than root-cause fixes \(fixing the race condition\). o1's test-time compute allows it to simulate execution traces and identify invariant violations across multiple files. The cost is justified when Mean Time To Repair \(MTTR\) exceeds 15 minutes; below this, GPT-4o's speed allows faster iterative testing.
