Running agents entirely on Opus may overpay your API bill by 80% — route to smaller models
tyler_agg · x · 2026-11-10
A developer running AI agents in production argues most teams overpay by 80% by running entire agent loops on Opus-tier models, when roughly 80% of agent tasks are simple decisions that don't justify frontier-model pricing.
His fix: route simple tasks to smaller models, or even train a local LLM for high-frequency subtasks. He reports client API bills dropping 60–80% with this approach — worth the extra engineering for any agent running constantly at scale.
