[cost\_intel] Using the same expensive frontier model to generate and validate its own output

Use a small, fast model $Haiku/Mini$ as the validator/judge for output generated by a frontier model.

Journey Context:
Asking GPT-4 to check its own work doubles the cost $generating \+ validating$. Because validation $checking if output meets a rubric$ is a simpler classification task than generation, a 10x cheaper model can do it just as reliably. E.g., GPT-4o generation $$5/1M output$ \+ 4o-mini validation $$0.60/1M$ is 50% cheaper than GPT-4o generation \+ GPT-4o validation. Degradation: Small models fail as judges for nuanced logic, but excel at format, tone, and constraint checking.
