[cost\_intel] Real-time chat UI or live collaboration features requiring sub-3-second response times

Never use full reasoning \(o1/o3\) in the critical path of synchronous UX. Use GPT-4o-mini or Claude 3.5 Haiku for <1s responses. Offload heavy reasoning to async background jobs or pre-compute drafts.

Journey Context:
Teams deploy 'thinking' models for customer-facing chat, but the 10-30s latency causes user abandonment rates >50%. The cost isn't just tokens; it's user churn. The viable pattern is pre-computation \(generating drafts in background\) or async processing \(send notification when reasoning completes\). The latency cliff is absolute: above 5s, perceived intelligence drops to zero regardless of answer quality.
