}'Free API and pricing notes
Trial API access or promotional credits may be available by account; confirm current AI21 Studio balance
AI21 Labs / AI21 Studio provides Jamba model APIs. It is useful for writing, knowledge-work, long-context, and OpenAI-compatible migration tests, but credits, model catalog, pricing, and regional availability must be verified in the current Studio dashboard.
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.
