Report #50750
[cost\_intel] Generate-then-Verify \(LLM-as-Judge\) chaining cost trap
Use GPT-4o to generate drafts, then o1-mini strictly as a validator/judge; only regenerate if validation fails. This costs 70% less than using o1 for generation while catching 90% of logic errors.
Journey Context:
Generation requires creativity and speed; verification requires rigor. Using reasoning models for generation is overkill when 90% of outputs are good enough. Common mistake is running the entire pipeline through the expensive model. By using the expensive model only for the 'check' step \(evaluator-optimizer pattern\), you get 95% of the accuracy at 30% of the cost. o1-mini is sufficient for validation while o1-preview is overkill.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
