Report #75920

[cost\_intel] Calling o1 in synchronous user-facing chat endpoints

Never use o1 in p99 latency-sensitive paths \(>2s\); use GPT-4o with retrieval or pre-computed reasoning templates for sync UX.

Journey Context:
o1-mini takes 10-30s. The HCI Doherty Threshold shows productivity collapses when response >400ms, and abandonment spikes >2s. Reasoning models are for async batch jobs \(nightly reports, code review\), not live chat. The 'latency cliff' is absolute.
