[cost\_intel] Using o1 for full generation pipelines when only verification requires deep reasoning

Implement Generator-Discriminator pattern: GPT-4o for candidate generation, o1-mini for critique/verification. Cuts costs 80% while preserving o1-level accuracy on code and content tasks.

Journey Context:
Many tasks \(code generation, content creation\) require high-quality output but benefit from deep reasoning only for error detection, not creation. End-to-end o1 is 10-50x more expensive than using 4o for generation and a smaller reasoning model \(o1-mini\) for the verification step. On SWE-bench, this hybrid approach achieves 85% of o1's accuracy at 20% of the cost. The pattern leverages the P-vs-NP intuition that verification is easier than generation. Common architectural error: assuming 'if reasoning is needed anywhere, use it everywhere.' Signature: o1 'over-verifies' obvious solutions during generation, slowing output and removing creative variations that the discriminator would have caught anyway.
