[cost\_intel] Using reasoning models for every turn in multi-turn conversations, recomputing reasoning from scratch

Use reasoning models only for the first turn \(problem decomposition\) or final synthesis; use standard models for intermediate clarification turns; cache reasoning steps via prompt engineering to avoid recomputation

Journey Context:
o1 models are stateless and re-compute their entire reasoning chain on every API call. In a 5-turn debugging conversation, using o1 for all turns costs 5x the reasoning tokens and 5x latency, even though turns 2-5 are just clarifications. Better architecture: Turn 1 uses o1 to generate a 'reasoning memo' \(architecture analysis, hypothesis list\). Turns 2-4 use GPT-4o with the memo in context for Q&A. Turn 5 uses o1 again only if a novel hard bug requires deep reasoning. This reduces cost by 70% and latency by 80% while preserving 95% of the reasoning quality. The anti-pattern is 'o1 for every turn' which creates O\(n\) cost scaling with conversation length.
