| Notes | Official Jamba API ref confirms endpoint https://api.ai21.com/studio/v1/chat/completions with OpenAI-style messages/model/max_tokens request shape, model aliases jamba-large and jamba-mini, SSE streaming, and function-type tool calling. Constraint per docs: streaming must be false when using tools; max output for Jamba models is 4096 tokens. Rate limits not published on the fetched page. OPERATOR MANUAL CHECK 2026-07-25 (Peter): AI21's free/trial signup path is CLOSED — trial credits no longer obtainable. Treat as unavailable for the free catalog; the Jamba API endpoint facts above remain doc-accurate but there is no current free access. REVISIT if AI21 reopens a free tier. |
