Vapi Voice AI

Vapi is a developer-oriented, cloud-native platform for building, testing, and deploying lifelike voice agents (such as IVR/phone support and voice assistants), designed to greatly simplify development complexity.

It is suitable for developers building voice-enabled applications such as customer support, outbound sales, and appointment management, as well as startup teams and enterprise technical departments, especially those seeking rapid prototyping and production-grade deployment of voice AI.

No. The platform already integrates and supports multiple mainstream AI models such as OpenAI, Anthropic, and Google. It also supports 'bring-your-own-model', allowing developers to connect custom or self-hosted models for maximum flexibility.

Leveraging WebRTC and other technologies, Vapi delivers end-to-end response latency under 500 milliseconds for smooth bidirectional voice interaction, supports natural interruptions and multi-turn conversations, and provides a near-human dialogue experience.

The platform adheres to enterprise-grade security and compliance standards such as SOC 2, HIPAA, and PCI, suitable for regulated industries like finance and healthcare, and includes built-in PII (personal identifiable information) redaction features to protect call data.

Primarily a pay-as-you-go model based on minutes of usage. For large-scale applications like contact centers, reserved capacity plans are available. Large enterprises can negotiate annual contracts, and startups may receive free credit.
