Observe mode — measure savings without touching a request · WCO.ai
Run the WCO decision engine against live production traffic in a read-only path. LiteLLM callback and Node middleware that provably return the same object they were given, plus OpenTelemetry attributes that carry counts and verdicts but never payload content.
The interactive playground and tools require JavaScript because they run the optimization engine locally in your browser rather than sending your data to a server.
