The default model is `xai-grok/grok-4.6` with a 500,000-token context window.
The provider reads xAI's model catalog and includes the server-hosted `x_search`
tool only when the selected model advertises `supportsBackendSearch`. Models
without that capability continue normally without hosted X Search. When enabled,
searches run inside xAI's Responses API and citations arrive as inline links.
The provider reads and caches xAI's online model catalog for both WebUI model
selection and runtime capabilities. Newly available models appear automatically;
when discovery fails, the last successful catalog or built-in fallback remains
available. The server-hosted `x_search` tool is included only when the selected
model advertises support. Models without that capability continue normally
without hosted X Search. When enabled, searches run inside xAI's Responses API
and citations arrive as inline links.
Hosted X Search is on by default to preserve this behavior. It can be turned off in the
WebUI provider settings or with `providers.xaiGrok.extraBody.tools: []`.

This selects `xai-grok/grok-4.6`. The WebUI model selector reads xAI's online
model catalog, so newly available subscription models appear without a nanobot
release. Online metadata is cached and enriched with nanobot's curated labels;
if xAI is temporarily unavailable, nanobot uses the last successful catalog or
a small built-in fallback instead of emptying the selector. The same catalog
controls whether the provider exposes the hosted `x_search` tool; models that do
not advertise support continue without hosted X Search.
When enabled, Grok can search current X posts and return inline source links
without invoking a local nanobot tool. Credentials are stored under the
active instance's `auth/xai.json` (normally `~/.nanobot/auth/xai.json`), not in
