Release notes

We now support state-of-the-art open source LLMs over our Chat Completions endpoint. All models were released in 2026 and are on the efficient frontier of cost per intelligence. Currently available in the US.

Telnyx Edge Compute lets developers run serverless functions directly on Telnyx's global edge infrastructure for low-latency communications and AI workloads.

Arcana V3 is here: the fastest, most natural multilingual TTS on the market, now live across Voice API, AI Agents, and Standalone TTS.

Testing AI assistants before deployment is critical but often tedious. The Telnyx Coval integration brings automated testing and QA directly into your AI assistant workflow, with one-click setup and multi-channel support.

Montreal is now available as the 9th anchorsite location, joining 8 existing sites across North America, Europe, Asia, and Australia. This addition provides lower latency for voice traffic in Eastern Canada and Northeastern US.

The new Telnyx LiveKit Plugin lets developers access multiple speech providers and carrier-grade infrastructure with a few lines of code.

Voice AI Assistants can now detect when a transferred call reaches voicemail and respond automatically. Configure your assistant to either stop the transfer and return to the caller, or leave a message and confirm delivery.

Configure adaptive jitter buffer settings on Credential, FQDN, and IP connections to reduce audio artifacts caused by network jitter — ideal for contact centers and VoIP deployments over variable networks.

Telnyx has added Full PSTN Replacement capabilities to seven new destinations across French overseas territories, bringing our international PSTN replacement coverage to 69 countries.

AI Missions is a task tracking and orchestration API designed for AI agents — not developers — to call directly. When your agent needs to coordinate multi-step outbound workflows, Missions provides the structure to plan, track, and persist that work.

Telnyx is introducing improvements to IP address assignment and session-level visibility within Private PGWs to support more granular traffic control and device management.

Voice quality can make or break your AI agent experience. Telnyx now offers ResembleAI voices, built on the Chatterbox model (ranked #1 open source Voice AI), delivering speech that preserves emotion, style, and accent.
