Vapi launches Agent Loop in early access
Start here
Vapi has released Agent Loop in early access, with general availability planned for early next year. According to Vapi, the harness builds a voice agent from a plain prompt, scores each call against a business goal, drafts fixes for missed goals, tests them in simulations, and then sends them to a slice of live traffic before full rollout. Human approval is required before any change ships. Agent Loop runs on Vapi primitives. Simulations, in which AI callers with distinct personalities run hundreds of conversations against a change before a real caller hears it, and Traffic Splitting, which sends a slice of live calls to a new version before rollout, are available in the dashboard now. Goals, Call Health and Experiments are listed as coming soon, and Vapi says the features will reach existing builders' dashboards over the coming months. Every Agent Loop agent is a real Vapi assistant, so engineers keep full dashboard and API access.

Vapi launched Agent Loop in early access, with GA planned for early next year, as a self-improving harness that builds a voice agent from a plain prompt, scores every call against a business goal, drafts fixes for the misses, tests them in simulations and ships them to a slice of live traffic before full rollout. The loop runs on Vapi primitives including Simulations and Traffic Splitting, available in the dashboard now, plus Goals, Call Health and Experiments, coming soon. Every Agent Loop agent is a real Vapi assistant, so engineers keep full dashboard and API access, and human approval is required before any change ships.
