[cost\_intel] Implementing o1 in multi-turn tool use agent loops

Use GPT-4o for sequential tool calling; reasoning models compound latency multiplicatively \(5 tools × 30s = 150s total\)

Journey Context:
Agent architectures with sequential tool dependencies \(search → calculate → validate\) multiply reasoning latency. Each step incurs 10-60s of thinking time. GPT-4o handles tool chains in <2s per step. Reserve reasoning models for single-shot analysis where all context is provided upfront, or parallelize tool calls with async batching. The 'latency volcano' makes interactive agents unusable with reasoning models.
