[cost\_intel] Deploying reasoning models in synchronous user-facing chat

Never use o1/o3 in sync UX requiring <2s responses; use them asynchronously \(pre-generation, background review\) or use GPT-4o with chain-of-thought prompting for live interactions.

Journey Context:
o1-preview has 10-60s latency due to chain-of-thought generation. This violates the Doherty Threshold \(400ms for flow\). Users abandon chat after 2s. Common anti-pattern: 'Ask AI' button calling o1 directly. Architectural fix: Use o1 to pre-generate draft answers stored in cache, or use it for async code review comments, never blocking the main thread.
