xAI provides direct, usage-billed API access to Grok models. This connection is separate from xAI Grok Subscription, which uses included SuperGrok or eligible X Premium+ plan capacity.

​
Get an API key

Create an API key in the xAI Console and enable billing for the account or team that should pay for Roomote usage.

​
Configuration

Add xAI in Settings > Models and paste the key, or configure:
Roomote exposes Grok models with the xai/ prefix. Connecting xAI seeds Grok 4.6 as the default coding model, and Grok chat models released after the connection appear automatically, without a Roomote update. Models you disable or remove stay that way. Deployments configured only through the XAI_API_KEY environment variable start picking up new models once model settings are first saved in Settings > Models. If both xAI API and a Grok subscription are connected, Roomote prefers the subscription for xai/ models.

​
Cost behavior

API-key requests are billed by xAI according to model usage. Roomote records tokens and estimates cost from model metadata; the xAI Console and API pricing are authoritative. When a subscription is also connected, requests may consume the subscription allowance instead of API credits because it takes precedence.

​
Verify setup

  1. save XAI_API_KEY
  2. confirm xAI models appear in Settings > Models
  3. pick a Grok chat model and assign it to a role
  4. run a small task and confirm usage in the xAI Console

​
Common issues

  • The API key is not used. Disconnect the Grok subscription if you want xai/ requests to use separately billed API capacity.
  • Authentication or credit errors occur. Check key status, team selection, billing, and spend limits in the xAI Console.
  • A model is unavailable. Refresh model metadata and confirm the API account can access the selected Grok model.
