153When `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.
