# Native OpenAI model support in Telnyx model selector

### 19, Nov 2025

OpenAI models gpt-5.1, gpt-5, gpt-4.1, and gpt-4o are now available directly in the Telnyx model selector. This update reduces external setup steps and gives teams a faster way to deploy OpenAI models across Voice AI, messaging, and automation workflows.

## What’s new

* **Native OpenAI models:** gpt-5.1, gpt-5, gpt-4.1, and gpt-4o selectable in the model dropdown.
* **Unified billing:** Usage billed by Telnyx at OpenAI list prices with no markup.
* **BYO OpenAI keys:** Optional override to connect your own API keys.
* **Consistent interface:** Same configuration flow as other Telnyx-hosted models.

## Why it matters

* Reduces integration friction for teams already using OpenAI.
* Simplifies cost tracking by consolidating usage into Telnyx billing.
* Improves deployment speed for new assistants.
* Supports easy migration from external agent platforms like ElevenLabs and Vapi.

## Example use cases

* Importing Retell, Vapi, or ElevenLabs assistants directly into Telnyx.
* Migrating existing OpenAI-powered voice or chat flows without code changes.
* Running model comparisons alongside other providers in the same workspace.

## Getting started

1. Open Mission Control Portal → AI Assistance → Model selector.
2. Choose an OpenAI model (gpt-5.1, gpt-5, gpt-4.1, or gpt-4o).
3. Save the assistant and run a test message or call.

**Try out the integration in the [Mission Control Portal](https://portal.telnyx.com/#/ai/assistants)**
