Vapi launches traffic splitting for voice agent rollouts

Vapi has launched traffic splitting, letting teams route 0.1%, 1% or 5% of inbound and outbound calls to a new agent version before committing. Previously, publishing a new assistant version sent 100% of traffic to it immediately. The feature includes "stickiness" to keep repeat callers on the same version, and Vapi recommends starting with two-way splits.
