Vapi logo

Vapi

Orchestration layer that stitches together third-party LLM, STT, and TTS providers (OpenAI, Deepgram, ElevenLabs and others) with telephony routed through Twilio or a carrier you supply.

One per-minute rate on an owned stack

Vapi's headline rate sits on top of separately metered LLM, STT, TTS, and telephony bills from each underlying vendor. Telnyx bundles STT, standard TTS, and orchestration into one rate on one contract, with LLM and telephony priced transparently on the same platform.
