Quick verdict

Free API: Unlimited self-hosted
Rate limits: Local/self-hosted
Best model starting point: Diffusion Engine for Musical Orchestrated Noise
Mainland China access: proxy/relay likely needed

Provider fit matrix

Best fit Private deployments, offline testing, and hardware-controlled inference

Watch out Ops, model downloads, GPU sizing, and concurrency are your responsibility

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)

Free API and pricing notes

Unlimited self-hosted

Project provides a local Session API; README also links to hosted trial at music.daydream.live.

Access and production risk

Relay or proxy may be needed

DEMON is an MIT-licensed streaming music/audio diffusion engine built on ACE-Step, with local deployment, TensorRT acceleration, node graph, and hosted demo.

How to set it up

Create or locate your provider API key in the official dashboard.

Install the OpenAI-compatible Python SDK or the provider-supported SDK.

Set the API key in an environment variable instead of hard-coding secrets.

Run a small DEMON chat completion with Diffusion Engine for Musical Orchestrated Noise.

Watch free credits, RPM/TPM limits, response shape, and error messages before scaling.
