SpaceXAI Supported Models ->An xAI key comes from the developer console, which bills separately from any consumer subscription at the same company. That console is also where the account's monthly cap lives.
A team account needs a payment method on file before the key does anything. Promotional credits, where granted, expire on a clock xAI sets. Rates and terms sit in the console's billing documentation.
Ctrl + Shift + M opens Models. Press More Services when the Setup AI Models wizard shows first, then Add -> xAI. Paste into API Key and press Models to fill the list (add and manage your keys).
There is no host field here: every request goes to xAI's own endpoint.
The console holds a monthly cap; above it, requests stop for the rest of the month. Usage alerts fire at 50, 75 and 90 percent of that cap. Set both there.
Direct Connection can be turned on once the key is in the browser. It starts off.
Direct Connection works only with your API key stored in the browser, and with an AI service that permits direct browser calls (CORS). Where it cannot be used, requests route through the Big-AGI fast edge servers instead - everything still works, within the standard upload size and time limits.
