Why this limit matters

Google: Gemini 2.5 Pro concurrency limit decides whether a key can enter a production route. TestKey reads model ID google/gemini-2.5-pro, provider Google, catalog context, real-key headers, 429 errors, and region signals together.

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 google/gemini-2.5-pro; limits from another model at the same provider cannot be reused.

Operator action

Google: Gemini 2.5 Pro concurrency limit is not just a number. It should become route throttling, sale tags, headroom alerts, fallback model suggestions, and price protection.
