Free API credits

Yes

Trial API access or promotional credits may be available by account; confirm current AI21 Studio balance · Account, model, and plan dependent

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 notes

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.

If multiple provider keys become painful, compare official providers, API gateways, and alternatives.

Recommended path

Start from the main AI21 Labs profile and confirm whether it fits your task.

Create an API key after signup and use the Trial API access or promotional credits may be available by account; confirm current AI21 Studio balance first.

Run one or two real tasks before paying or switching providers.

If access is unstable, compare relay options or local alternatives.

Production decision checks

Production budget

AI21 Labs free credits are for validation. Before launch, record cost per 1K requests, retry-adjusted cost, and a monthly spend cap.

Compatibility check

If you already use the OpenAI SDK, verify AI21 Labs base URL, model names, streaming, tool calling, and JSON mode before migration.

Fallback rule

Keep one similar provider or OpenLLMAPI route ready so credit exhaustion, regional access issues, or model deprecations do not break users.
