AI Models

Frontier reasoning models vs Fast utility models

The wrong default model usually fails in one of two ways: slow expensive answers everywhere, or cheap answers where the mistake costs more than the tokens. The useful pattern is a routed stack that escalates only when the task needs deeper judgment.

Quality escalation vs throughputFrontier reasoning for review gates, fast utility models for routine production flow.
Option A

Frontier reasoning models

Code review, architecture decisions, agent planning, research synthesis, and high-risk support escalations.

Option B

Fast utility models

Bulk extraction, summaries, first drafts, customer macros, tagging, and low-risk automation.
