Codex tip: Dynamically routing reasoning effort saves tokens
RileyRalmuto · x · 2026-08-13
Shares a cost optimization technique when using Codex to orchestrate large agent swarms.
It recommends dynamically coordinating reasoning effort and model selection based on task complexity rather than maxing out settings globally. For instance: use Medium for normal coordination; Low for mechanical UI and documentation; escalate to High or Ultra only for difficult integrations like schema migrations or key custody, and final app stages. This approach saves more tokens than working linearly without sacrificing quality.
