Quick verdict

Free API: New-account Databricks trial credits can be used to test Mosaic AI model serving where available
Rate limits: Endpoint, region, model, and workspace quota dependent; check Serving endpoints and billing dashboard
Best model starting point: databricks-meta-llama-3-1-70b-instruct
Mainland China access: proxy/relay likely needed

Provider fit matrix

Best fit Fast provider evaluation, prototypes, and fallback routing

Watch out Free credits and rate limits can change without warning

Production fallback Keep at least one compatible backup provider before shipping

Production readiness checklist

Quota gate Start inside New-account Databricks trial credits can be used to test Mosaic AI model serving where available; 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: 2026-06-16; official quota and pricing can change without notice.

Python setup snapshot

Start with the smallest possible serving endpoint invocation, then move the key to your server-side secret manager before production.

import os
import requests

workspace_host = os.environ["DATABRICKS_HOST"].rstrip("/")
token = os.environ["DATABRICKS_TOKEN"]
endpoint = os.environ.get("DATABRICKS_SERVING_ENDPOINT", "databricks-meta-llama-3-1-70b-instruct")

response = requests.post(
    f"{workspace_host}/serving-endpoints/{endpoint}/invocations",
    headers={"Authorization": f"Bearer {token}", "Content-Type": "application/json"},
    json={"messages": [{"role": "user", "content": "Say hello from yangmao.ai"}]},
    timeout=60,
)
response.raise_for_status()
print(response.json())

Free API and pricing notes

New-account Databricks trial credits can be used to test Mosaic AI model serving where available

Mosaic AI is not a public no-card free API. It is best for teams with a Databricks/cloud workspace that want to use trial credits to validate serving endpoints, logging, permissions, and cost.

Access and production risk

Relay or proxy may be needed

Test Databricks console access, cloud region, enterprise network, billing, and serving endpoint latency from mainland China; keep a China-accessible fallback gateway for production.

How to set it up

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

Install the provider SDK or requests dependency shown in the example.

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

Run a small Databricks Mosaic AI serving endpoint invocation with databricks-meta-llama-3-1-70b-instruct.

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

Databricks Mosaic AI production validation table

Use this table before sending real users, scheduled agents, or paid traffic to Databricks Mosaic AI. The goal is to validate source freshness, quota behavior, regional access, and fallback needs instead of trusting a stale free-credit claim.

Check Pass condition If it fails

Signup and billing state Key creation works and the account can spend the recorded New-account Databricks trial credits can be used to test Mosaic AI model serving where available. Compare Databricks Mosaic AI alternatives or route through a gateway before inviting users.

First request from target region Proxy, relay, or non-mainland deployment path is documented before launch. Do not ship cron jobs or public demos until latency, DNS, TLS, and auth are repeatable.

Quota, retry, and error shape Rate-limit behavior matches the current Endpoint, region, model, and workspace quota dependent; check Serving endpoints and billing dashboard note or official dashboard values. Cap retries, add request logging, and keep a second route for 429/5xx bursts.

Cost per accepted task Real prompts stay within your target token, query, image-credit, or compute budget. Use cheaper primary routes, caching, shorter prompts, or fallback only after validation failure.

FAQ

Does Databricks Mosaic AI have a free API?

Yes. Current yangmao.ai record: New-account Databricks trial credits can be used to test Mosaic AI model serving where available. Rate limit note: Endpoint, region, model, and workspace quota dependent; check Serving endpoints and billing dashboard.

Is Databricks Mosaic AI OpenAI-compatible?

This snapshot uses a provider-specific Databricks Serving Endpoints example. If your app requires one stable OpenAI-compatible endpoint, use an aggregator or relay after checking Databricks Mosaic AI docs.

Can I use Databricks Mosaic AI from mainland China?

Databricks Mosaic AI may need a proxy or relay from mainland China. Test latency and signup before production.
