[cost\_intel] Using GPT-4o as the planner in a ReAct agent with >5 tools

Use o1 for the planning step \(selecting tool sequence\), 4o for tool execution; reduces hallucinated tool calls by ~60% when tool count exceeds 5

Journey Context:
4o plans often contain impossible sequences \('use calculator then search then calculator' when context changed\). o1 simulates consequences of tool calls via internal reasoning. Pattern: o1 generates plan/DSL once per task, 4o executes individual steps. Cost is optimized because o1 runs once, 4o runs per step \(cheap\).
