Single-Hop Latency Flatters LLM Routers: Chained Calls Expose Cascading Model-Pick Errors
ScottShapiroUXD · x · 2026-09-19
Reacting to the 679ms Auto-LLM-Router demo, ScottShapiroUXD points out that single-hop latency flatters routers: the real test is chaining three or four routed calls, where one bad early model pick cascades downstream. A sharp reminder that LLM router evaluation should measure end-to-end quality in chained scenarios, not one-shot latency.
