Access and production risk

Relay or proxy may be needed

Mainland China access is unconfirmed. For China-facing users, test the website, Studio, API domain, DNS/TLS, payment, and first request, and keep OpenLLMAPI, Qwen, DeepSeek, or SiliconFlow as fallbacks.

Decision checklist

Check AI21 Labs free credits and rate limits.

Compare same-category providers and Mainland China access needs.

Pick the provider with the clearest no-card/free API path for testing.

AI21 Labs production validation table

Use this table before sending real users, scheduled agents, or paid traffic to AI21 Labs. 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 Trial API access or promotional credits may be available by account; confirm current AI21 Studio balance. Compare AI21 Labs 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 Account, model, and plan dependent 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.
