Python setup snapshot
Start with the smallest possible chat completion, then move the key to your server-side secret manager before production.
from openai import OpenAI
client = OpenAI(
api_key="vllm-local",
base_url="http://localhost:8000/v1",
)
response = client.chat.completions.create(
model="Qwen/Qwen2.5-7B-Instruct",
messages=[{"role": "user", "content": "Hello from yangmao.ai"}],
)
print(response.choices[0].message.content)cURL smoke test

-H "Content-Type: application/json" \
-d '{
"model": "OpenAI-compatible server",
