How to get Together AI API key

Quick answer

To get a Together AI API key, sign up at the Together AI website and create an account. After logging in, navigate to the API keys section in your dashboard to generate and copy your API key for use in your Python projects.

PREREQUISITES

Python 3.8+
pip install openai>=1.0
Together AI account

Setup

First, create a Together AI account at their official website. Once registered, log in to access your dashboard where you can generate your API key. Install the openai Python package to interact with Together AI's OpenAI-compatible API.

bash

pip install openai

Step by step

Use your Together AI API key with the OpenAI-compatible openai Python SDK by setting the TOGETHER_API_KEY environment variable. Then create a client and call the chat completion endpoint with a Together AI model.

python

import os
from openai import OpenAI

# Set your Together AI API key in environment variable TOGETHER_API_KEY
client = OpenAI(api_key=os.environ["TOGETHER_API_KEY"], base_url="https://api.together.xyz/v1")

response = client.chat.completions.create(
    model="meta-llama/Llama-3.3-70B-Instruct-Turbo",
    messages=[{"role": "user", "content": "Hello from Together AI!"}]
)

print(response.choices[0].message.content)

output

Hello from Together AI! How can I assist you today?

Common variations

You can use different Together AI models by changing the model parameter. For asynchronous calls, use an async client pattern with asyncio. Streaming responses are supported by setting stream=True in the request.

python

import os
import asyncio
from openai import OpenAI

async def main():
    client = OpenAI(api_key=os.environ["TOGETHER_API_KEY"], base_url="https://api.together.xyz/v1")
    
    stream = client.chat.completions.create(
        model="meta-llama/Llama-3.3-70B-Instruct-Turbo",
        messages=[{"role": "user", "content": "Stream a response from Together AI."}],
        stream=True
    )

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

asyncio.run(main())

output

Streaming response text printed token-by-token...

Troubleshooting

If you get authentication errors, verify your TOGETHER_API_KEY environment variable is set correctly.
Check your account dashboard to ensure your API key is active and has usage quota.
Use the correct base URL https://api.together.xyz/v1 for the Together AI API.
