Vapi CLI

Vapi CLI is a powerful tool designed to help developers and businesses build and deploy voice agents with ease. It is part of the Vapi platform, which is used by innovative startups and large corporations alike. The platform is known for its high level of configurability, making it a top choice for creating advanced voice AI products and scaling phone operations.

Vapi CLI supports multilingual communication, allowing users to interact with voice agents in a wide range of languages, including English, Spanish, Mandarin, and over 100 others. This makes it a versatile tool for businesses operating in diverse markets. The platform is API-native, meaning everything is exposed as an API, offering thousands of configurations and integrations. This flexibility allows users to tailor the platform to their specific needs.

One of the standout features of Vapi CLI is its automated testing capabilities. Users can design test suites of simulated voice agents to identify and mitigate hallucination risks before deploying their agents to production. This ensures a high level of accuracy and reliability in the voice agents' responses.

Vapi CLI also allows users to bring their own models. This can be done by integrating API keys for transcription, LLM, or text-to-speech models, or by plugging in their own self-hosted models. This feature provides users with the flexibility to use their preferred models and customize the platform to their specific requirements.

The platform supports tool calling, enabling users to plug in their APIs as tools. This allows the voice agents to intelligently fetch data and perform actions on the user's server. This feature enhances the functionality of the voice agents and makes them more useful in real-world applications.

Additionally, Vapi CLI offers A/B experiments. This feature allows users to test different variations of prompts, voices, and flows. By continuously optimizing these elements, users can improve the performance of their voice agents and provide a better user experience.

In summary, Vapi CLI is a versatile and powerful tool for building and deploying voice agents. Its multilingual support, API-native platform, automated testing, and customization options make it a top choice for businesses looking to enhance their voice AI capabilities.
