About Telnyx
Telnyx pulls the whole agent stack onto its own platform — and cuts voice AI loose from the phone line
Telnyx is shipping on two tracks at once. The steady one is model plumbing: GPT-5.4-mini, Kimi K3 on Inference, then GLM-5.2 and two GPT-5.6 variants, each slotted into Voice AI Assistants at a different cost-versus-reasoning point. The consequential one is structural — Edge Compute launched an Agent Runtime with Functions, KV, Cloud Storage, and Inference all GA, and Voice AI conversations now run over a direct WebSocket with no telephony involved. An Email API also entered beta, adding another channel to the same bill.
