[cost\_intel] Using reasoning models for deterministic algorithm implementation

Use Claude 3.5/4 Sonnet or GPT-4o for LeetCode-style problems; o3 shows no advantage on deterministic algorithms with known optimal solutions

Journey Context:
Benchmarks on HumanEval and LiveCodeBench show o3-mini and GPT-4o achieve near-identical pass@1 on standard algorithms \(sorting, graph traversal, DP\). Reasoning overhead adds 3-10x latency for zero quality gain. The delta appears only on 'ambiguous requirements' or 'novel problem decomposition'. For 'implement Dijkstra', instruct models are saturated; for 'design a cache eviction strategy given these conflicting constraints', reasoning earns the 10x premium.
