OpenAI Enterprise for developers

Quick answer

OpenAI Enterprise provides developers with dedicated API keys, enhanced security, and scalable infrastructure for production AI applications. Use the standard OpenAI SDK with your enterprise API key set in os.environ["OPENAI_API_KEY"] to access enterprise features seamlessly.

PREREQUISITES

Python 3.8+
OpenAI Enterprise API key
pip install openai>=1.0

Setup

Install the official openai Python package and set your OpenAI Enterprise API key as an environment variable for secure authentication.

bash

pip install openai>=1.0

output

Collecting openai
  Downloading openai-1.x.x-py3-none-any.whl (xx kB)
Installing collected packages: openai
Successfully installed openai-1.x.x

Step by step

Use the OpenAI SDK to call the API with your enterprise key. This example sends a chat completion request to gpt-4o, the recommended model for enterprise workloads.

python

import os
from openai import OpenAI

client = OpenAI(api_key=os.environ["OPENAI_API_KEY"])

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Hello from OpenAI Enterprise!"}]
)

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

output

Hello from OpenAI Enterprise! How can I assist you today?

Common variations

Use gpt-4o-mini for lower latency and cost.
Enable streaming by adding stream=True to chat.completions.create.
Use async calls with asyncio and await for concurrency.

python

import os
import asyncio
from openai import OpenAI

async def main():
    client = OpenAI(api_key=os.environ["OPENAI_API_KEY"])
    stream = await client.chat.completions.create(
        model="gpt-4o-mini",
        messages=[{"role": "user", "content": "Stream a response."}],
        stream=True
    )
    async for chunk in stream:
        print(chunk.choices[0].delta.content or "", end="", flush=True)

asyncio.run(main())

output

Streaming response text appears here in real time...

Troubleshooting

If you get 401 Unauthorized, verify your OPENAI_API_KEY is correct and has enterprise access.
For 429 Rate Limit errors, check your enterprise quota and request an increase if needed.
Ensure your network allows outbound HTTPS requests to api.openai.com.

✅

Key Takeaways

Use the official openai SDK with your enterprise API key for seamless integration.
Enterprise keys provide enhanced security, higher rate limits, and dedicated support.
Streaming and async calls improve responsiveness for production applications.
