Report #59705

[cost\_intel] Latency timeout when using o1-mini for real-time code completion

For standard boilerplate, API client generation, and CRUD endpoints, use Claude 3.5 Sonnet or GPT-4o with <1s latency; reserve reasoning models for algorithmic optimization or debugging complex race conditions where the bug requires >10 reasoning steps.

Journey Context:
Developers try o1 for autocomplete due to hype. But reasoning models have 10-30s latency vs <1s for 4o. UX breaks. Also, for common patterns, reasoning adds no quality—both achieve >90% pass rate on HumanEval easy. The cost is 20x for zero gain. The latency cliff is absolute: if your UX requires <2s response, o1 is architecturally incompatible regardless of quality.
