Question 1

What is thru.ai?

Accepted Answer

thru.ai is a meta-infrastructure voice agent platform that replaces Twilio, Deepgram, ElevenLabs, and OpenAI with a single API. Developers and AI agents can deploy production voice agents in minutes with one API key, one bill, and 5+ provider integrations.

Question 2

How does thru.ai work?

Accepted Answer

thru.ai abstracts the entire voice stack behind a single REST API. It orchestrates speech-to-text (Deepgram, Google), large language models (Groq, OpenAI, Anthropic), text-to-speech (Cartesia, ElevenLabs), and telephony (Twilio) into a unified pipeline with sub-200ms latency. Create an agent, assign a phone number, and start taking calls in under 5 minutes.

Question 3

What providers does thru.ai support?

Accepted Answer

thru.ai supports 5+ providers across the voice stack: Deepgram and Google Cloud for speech-to-text, Groq (Llama) and OpenAI for LLM processing, Cartesia, ElevenLabs, Google Cloud TTS, and OpenAI Realtime for text-to-speech, and Twilio for telephony. Swap providers with a single PATCH request.

Question 4

How much does thru.ai cost?

Accepted Answer

thru.ai offers flexible pricing: Pay As You Go at $0/month with usage-based billing, Starter at $99/month with 500 minutes included, and Pro at $249/month with 2,000 minutes included. One API key replaces four vendor contracts and four separate bills.

Question 5

Can AI agents use thru.ai?

Accepted Answer

Yes. thru.ai is designed for both human developers and AI agents. The platform exposes machine-readable discovery via /.well-known/ai-plugin.json, agents.json, and llms.txt. AI agents like LangChain, CrewAI, and custom GPTs can discover, provision accounts, and deploy voice agents autonomously through the REST API.
