Web Search
AI with live web access.
Built-in web search can provide current results with source citations when an approved search or model provider is available in the selected zone.
Current web sources
Approved search features can find current webpages for a request and make them available for the answer.
Approval per data zone
Managed web search is enabled only after separate approval; required search terms and explicitly requested URLs may be sent to the search provider.
Trace the sources
Where the feature supplies sources, links are displayed. Content and conclusions should be reviewed independently before consequential use.
Support research
Search results can be collected and summarised; availability and scope depend on the model, search provider and approval.
