[cost\_intel] When does o1/o3 beat GPT-4o by >20% on coding tasks?

Use o1/o3 for competitive programming, geometry algorithms, and constraint satisfaction problems; use GPT-4o for standard business logic CRUD.

Journey Context:
Benchmarks show o1 achieves 62% on LiveCodeBench vs GPT-4o's 35%, but on HumanEval \(simple functions\) the gap closes to <5%. The 20% threshold is crossed when problems require >3-step logical deduction or mathematical proofs. GPT-4o 'greedily' generates plausible-looking code that fails edge cases in geometric algorithms. Cost is 30-50x higher for o1, so the breakpoint is task complexity, not code volume.
