Report #65713

[cost\_intel] When is it cheaper to use GPT-4o to generate and o1-mini to verify versus using o1 throughout?

Use GPT-4o for generation \+ o1-mini for binary pass/fail verification when the output is <500 tokens and the error mode is subtle logic \(not syntax\); use o1 for generation only when the output must be correct on first try \(e.g., single-shot SQL migrations\).

Journey Context:
o1 is optimized for 'finding the right answer' not 'generating fluent text'. In coding tasks, GPT-4o generates syntactically correct but logically buggy code 30% of the time on complex functions. Verifying with o1-mini \(which is good at logic checking\) costs $0.60 per 1M tokens vs generating with o1 at $60 per 1M tokens. The break-even is verification of ~100 GPT-4o generations vs 1 o1 generation. However, for migrations where you can't iterate, o1's first-shot correctness pays for itself.
