⚡ 3-Minute Quickstart

Almost every modern LLM API is OpenAI-compatible. Just swap the base_url and api_key:

from openai import OpenAI

# Any OpenAI-compatible provider works this way
client = OpenAI(
    api_key="YOUR_API_KEY",                   # From the provider console
    base_url="https://api.deepseek.com/v1"   # Swap per provider
)

response = client.chat.completions.create(
    model="deepseek-chat",
    messages=[{"role": "user", "content": "Hello"}]
)
print(response.choices[0].message.content)

Common base_url cheat-sheet:
