Model limit probe

xAI: Grok Code Fast 1 | region and IP limit

xAI: Grok Code Fast 1 region and IP limit decides whether a key can enter a production route. TestKey reads model ID x-ai/grok-code-fast-1, provider xAI, catalog context, real-key headers, 429 errors, and region signals together.

Why this limit matters

xAI: Grok Code Fast 1 region and IP limit decides whether a key can enter a production route. TestKey reads model ID x-ai/grok-code-fast-1, provider xAI, catalog context, real-key headers, 429 errors, and region signals together.

How to prove it

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

Start with the visible signal: catalog plus runtime, then read headers and error bodies with read-only requests.
region and IP limit must bind model ID x-ai/grok-code-fast-1; limits from another model at the same provider cannot be reused.

Operator action

xAI: Grok Code Fast 1 region and IP limit is not just a number. It should become route throttling, sale tags, headroom alerts, fallback model suggestions, and price protection.
