[cost\_intel] Reasoning models cause request timeouts in interactive applications

Cap reasoning models to asynchronous pipelines \(CI, batch processing\); for sync UX \(>3s latency unacceptable\), use instruct models with speculative execution or chain-of-thought prompting

Journey Context:
o1-mini takes 5-15s; o1 takes 30-120s. Human perception threshold for 'flow state' in coding assistants is ~1-2s. Using reasoning in live chatbots creates UX friction and timeouts. Alternative: Use GPT-4o/Claude 3.5 Sonnet with 'think step by step' prompt for medium complexity, or use cascade pattern: fast model streams response, slow model validates in background. Production systems should implement adaptive routing: classify query complexity \(via embeddings or lightweight classifier\) and route to reasoning only if complexity score > threshold.
