Chat Completions Quickstart

Sign up for a Telnyx mission control portal account

If you haven't already, head to to sign up for your free Telnyx account. It’ll give you access to our Mission Control Portal where you can chat with language models running on Telnyx in the AI Playground.

You can use the system prompt to give context and instructions before asking a question to a model. For example, users can specify a role, how to personalize the response, or what tone to use.

You can also choose from a variety of open-source models or pass us your OpenAI API key to use their models. For the open source models:

Quickstart 0

Video Demonstration using System Prompts and AI Storage

You can also use AI-enabled Telnyx Storage buckets to provide context that won't fit in the system prompt. We will cover this in more detail in a future tutorial.

Using the API

You can also use our OpenAI-compatible chat completions API to interact programmatically with a language model.

Getting a v2 API Key

You can create a v2 API Key using these instructions.

Python Example

Here is some simple Python to stream a chat response using Telnyx.

import os
from openai import OpenAI

client = OpenAI(

chat_completion =
"role": "user",
"content": "Can you explain 10DLC to me?"

for chunk in chat_completion:
if chunk.choices[0].delta.content:
print(chunk.choices[0].delta.content, end="", flush=True)
