[cost\_intel] Reasoning model latency breaking synchronous user interfaces

Never use o1/o3 for chat streaming requiring <3s first token. Chain: fast instruct model \(GPT-4o-mini\) for initial response \+ async reasoning check for correction. Speculative execution: 4o answers immediately, o1 validates in background, streams correction only if delta > threshold \(cosine sim < 0.9\).

Journey Context:
Teams try o1 for 'better answers' in chatbots. Result: 15-30s latency kills engagement. The fix is speculative execution: 4o answers immediately, o1 validates in background, streams correction only if delta > threshold \(cosine sim < 0.9\). This preserves 'conversation' feel while gaining accuracy only where needed.
