Python
import openai

client = openai.OpenAI(
    api_key="YOUR_LLM_GATEWAY_API_KEY",
    base_url="https://api.llmgateway.io/v1"
)

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Hello, how are you?"}]
)
print(response.choices[0].message.content)
RELIABILITY

Never go down. Even when your providers do.

LLM Gateway automatically routes requests to healthy providers in real-time. When one goes down, your traffic seamlessly fails over—your users never notice.
