Engineers debate when to abandon AI agentic loops for simpler deterministic systems

An Ask HN thread asks engineers about moving away from complex autonomous agentic loops and feedback chains toward more deterministic approaches.

Agentic systems are characterized by significant latency, non-determinism, low accuracy, and cost challenges that prompted the switch.

Engineers are asked to identify specific failure modes—reliability, cost, latency, or maintainability—that drove their decision to replace agentic approaches with deterministic pipelines.
