Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

 ## Model discovery
 
-When `ANTHROPIC_BASE_URL` points at a gateway that exposes the Anthropic Messages format, Claude Code can query the gateway's `/v1/models` endpoint at startup and add the returned models to the `/model` picker.
+When `ANTHROPIC_BASE_URL` points at a gateway that exposes the Anthropic Messages format, Claude Code can query the gateway's `/v1/models` endpoint at startup and add the returned models to the `/model` picker. If you or your administrator set `replaceBuiltInOptions` in a [`modelPicker`](/docs/en/settings-reference#modelpicker) lineup, Claude Code hides the discovered models from the picker.
 
 Developers enable it by setting [`CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1`](/docs/en/env-vars), in their own environment or through managed settings. Discovery is off by default so that gateways backed by a shared API key don't surface every model the key can access to every user.
