Production fallback Keep a hosted OpenAI-compatible fallback for spikes and outages

Production readiness checklist

Quota gate Start inside Unlimited self-hosted; log usage before adding retries or batch jobs.
No-card check Try the free path first, then confirm whether billing is required for API keys, higher RPM, or production endpoints.
Regional smoke test Run signup, dashboard, DNS, TLS, and first API call checks from mainland China before launch.
Source freshness Snapshot date: 2026-05-28; official quota and pricing can change without notice.

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="your-demon-key",
    # Check DEMON docs for its OpenAI-compatible base URL
)

response = client.chat.completions.create(
    model="Diffusion Engine for Musical Orchestrated Noise",
    messages=[{"role": "user", "content": "Hello from yangmao.ai"}],
)
print(response.choices[0].message.content)

cURL smoke test

Use this to verify endpoint, auth header, model name, response shape, and quota before adding SDK abstractions.

curl https://api.provider.example/v1/chat/completions \
  -H "Authorization: Bearer $DEMON_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "Diffusion Engine for Musical Orchestrated Noise",
    "messages": [{"role": "user", "content": "Hello from yangmao.ai"}]
  }'
