Deterministic routing beats LLM quality gates in agent pipelines
A developer proposes replacing LLM-based quality gates with deterministic routing and sampling. Experiments show LLM judges misclassify 50% of outputs and reject 75% of valid work. The alternative uses task-type routing, diff reviews, and sampling strategies to reduce reliance on LLM judgment.
Meridian48 take
The approach challenges the industry's reflex to layer more LLMs on top of LLMs, but its real-world adoption depends on how well task classification can be automated without introducing new failure modes.
