This article is generated from RelayRank monitoring samples and common relay selection questions to provide a practical decision framework.
What to watch
This week's monitored samples include YunDou, infai, toproutercn, lingxicode, SudoCode, Aiide. They help turn metrics into operational judgement.
Do not judge a relay by one metric. Availability, latency, status changes, model coverage, billing rules, and transparency should be read together.
Practical advice
A weekly report should track trends instead of chasing noise. Reliability needs repeated observation.
Before long-term use, run small real-task tests and keep at least one backup endpoint.
