Model limit probe

AI21: Jamba Large 1.7 | concurrency limit

AI21: Jamba Large 1.7 concurrency limit decides whether a key can enter a production route. TestKey reads model ID ai21/jamba-large-1.7, provider AI21, catalog context, real-key headers, 429 errors, and region signals together.

Why this limit matters

AI21: Jamba Large 1.7 concurrency limit decides whether a key can enter a production route. TestKey reads model ID ai21/jamba-large-1.7, provider AI21, catalog context, real-key headers, 429 errors, and region signals together.

Model: ai21/jamba-large-1.7
Provider: AI21
Limit dimension: concurrency limit

How to prove it

Read-only check. Detection data burns after 5 minutes.

Start with the visible signal: real key probe required, then read headers and error bodies with read-only requests.
concurrency limit must bind model ID ai21/jamba-large-1.7; limits from another model at the same provider cannot be reused.

Operator action

AI21: Jamba Large 1.7 concurrency limit is not just a number. It should become route throttling, sale tags, headroom alerts, fallback model suggestions, and price protection.
