Telnyx AI Agent Platform

What it does

The Telnyx Agent Platform is a service for building and running voice AI agents that answer calls on real phone numbers. Telnyx describes it as a platform that owns the entire stack, from the GPUs that host speech and AI models to phone numbers and telephony, delivered through one API and one bill.

An agent can be defined with a single prompt in the portal's no-code builder, or scaffolded from the Telnyx GitHub repo with a coding agent. After picking a voice and attaching a number, the agent can be tested with simulated calls in the in-browser tester, then published to a real number and monitored end to end with AI Insights. Agents from Vapi, Retell or ElevenLabs can be imported, with prompts, voices and tool configs carried over.

It suits developers and voice teams who want speech recognition, inference, voice and telephony from a single vendor. A Telnyx account is required, and the platform can also be reached through the API, SDK or CLI. Plan details and the agent runtime options should be confirmed with Telnyx before budgeting.
