Does it support streaming?

Yes. Pass stream=True and iterate over the chunks as the SDK documents.

How do I handle errors?

The SDK raises exceptions carrying the HTTP status and error code; see common errors. 429 and 503 can be retried with backoff.

Connect OpenAI Python SDK

Updated 2026-09-23

The official Python SDK; two arguments point it at our endpoint.

Use cases

Good for calling models from your own Python services. The official SDK needs only base_url and api_key changed, and existing code mostly stays the same.

Tips

Read the key from a server-side environment variable; never commit it or ship it in frontend bundles.

If it cannot connect

Use https://omnimodel.me/v1 as the API host, without /chat/completions.
The key starts with key_ and is not paused or revoked; auth.invalid_key means the key cannot be used.
The model ID matches the catalog and is in the key's allowed models.
billing.insufficient_credit means the balance is too low; see common errors for more.

Setup

Install the dependency: pip install openai.
Point base_url at the API host below and pass your own key.
Everything else matches the official SDK.

Settings

API host：https://omnimodel.me/v1
API key：YOUR_API_KEY
Model：MODEL_ID

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://omnimodel.me/v1",
)
resp = client.chat.completions.create(
    model="MODEL_ID",
    messages=[{"role": "user", "content": "你好"}],
)
print(resp.choices[0].message.content)
