The Sudo developer platform maintains parity with the OpenAI Chat Completions API, allowing you to use the OpenAI SDK to access Sudo’s AI routing. By changing just two parameters, you can use the OpenAI SDK to build with Sudo today.
This compatability is not suitable for future-proof and production use cases, and is better for testing and validation.
Recall that each model provider has different degrees of support for OpenAI features (e.g. Anthropic models do not support response_format parameter). You must refer to their documentation of OpenAI compatability when in doubt

​
Using the OpenAI SDK

Using an official SDK by OpenAI, do the following:
  1. Change the base URL to Sudo’s chat API URL: https://sudoapp.dev/api/v1/
  2. Change the API key to your Sudo API key, which you can get from the dev dashboard.
Now, you can call Sudo’s chat API with any supported AI model of your choice. 
import openai

# Replace with your Sudo API key
openai.api_key = "your-sudo-api-key"
# Set the custom base URL
openai.base_url = "https://sudoapp.dev/api/v1/"

# Make a test call to the chat endpoint
response = openai.chat.completions.create(
    model="claude-sonnet-4-20250514",  # or "gpt-4", "gemini-2.0-flash", etc.
    messages=[
        {"role": "user", "content": "Hello! What is the capital of France?"}
    ],
    temperature=0.7,
)

print("Response:")
print(response.choices[0].message.content)
