Agent Loop is here: Better voice agents, every call

Vapi has launched Agent Loop in early access, a self-improving harness on top of its voice agent platform that builds an agent from a plain prompt, scores every call against a business goal, clusters misses into issues, drafts and tests fixes, then ships them as experiments on a slice of live traffic with automatic rollback. It relies on primitives including Simulations and Traffic Splitting (available in the dashboard now) and Goals, Call Health and Experiments (coming soon), with human approval required before any change ships. GA is planned for early next year, and Vapi is taking waitlist signups ahead of VapiCon on November 11.
