[cost\_intel] When is chaining cheap generation \+ reasoning verification better than full reasoning?
For code review/debugging: Generate 3 candidates with GPT-4o-mini \($0.003\), then use o1 to select/merge \($0.05\) = 60% cost of o1-generation with 90% accuracy; pure o1 generation costs $0.08.
Journey Context:
The cost-accuracy curve exhibits diminishing returns for generation versus discrimination. Reasoning models excel at verification \(spotting errors in proposed solutions\) due to their ability to simulate execution traces and edge cases. However, using them for generation is computationally wasteful because sample diversity matters more than per-sample reasoning depth. The optimal architecture is a cascade: a cheap instruct model generates diverse candidates \(exploiting high temperature\), then a reasoning model acts as a judge \(discriminator\). This exploits the 10x cost difference between generation tokens and reasoning tokens while preserving 90%\+ of accuracy.
