[cost\_intel] Deploying reasoning models for real-time customer support chat

Never use o1/o3 for real-time chat \(10-30s latency\). Use 4o for conversation flow, escalate to o1 only for 'hard' turns detected by uncertainty heuristics \(high token perplexity or user frustration signals\).

Journey Context:
A support chat with o1 takes 15 seconds per reply. Users think the bot is broken and abandon the session after 3 seconds of silence. The cost is also $0.50 per message vs $0.005. The solution is architectural: use GPT-4o or Claude 3.5 Sonnet for immediate replies \(<500ms\) with streaming. Implement an 'uncertainty detector' that monitors 4o's logprobs—if the top token probability is <0.7 or the user sends a 'you're wrong' message, trigger an o1 'advisor' call in the background to generate a corrected response for the next turn. This preserves the conversational 'illusion of speed' while leveraging deep reasoning only when necessary.
