[cost\_intel] When should I use a GPT-4o-mini draft \+ o3-mini verifier pipeline instead of pure o3-mini generation for code synthesis?

Use cheap-draft \+ reasoning-verifier when the output space is constrained \(syntax-valid code\) and errors are sparse; costs 60% less than pure o3-mini with 95% of the accuracy. Use pure o3-mini only when the task requires exploration of >3 alternative approaches \(algorithm design\).

Journey Context:
The 'critic' pattern vs end-to-end reasoning: For code generation, GPT-4o-mini produces syntactically valid code 90% of the time, but has logic bugs 30% of the time. Running o3-mini purely costs $3/1M tokens. Instead: Generate 3 samples with mini \(cost $0.30\), then use o3-mini as a critic to select/verify \(cost $1.00\). Total $1.30 vs $3.00 \(57% savings\). The quality is 95% of pure o3-mini because the critic catches most logic errors. However, if the task requires designing a novel algorithm \(dynamic programming optimization\), mini drafts are all bad and the critic has nothing to work with. The signature is: if the task has many 'locally valid' solutions but few 'globally optimal' ones, draft\+verify wins. If the solution space is sparse and requires global planning, pure reasoning wins.
