Integrations
Regions
Global endpoint; enterprise mTLS option is documented separately.
Governance / privacy
Realtime information requires search tools; the base model itself does not automatically have live-event data.
xAI documents model aliases and version-pinned IDs for consistency.
Benchmarks
Pending methodology-aware benchmark audit unless separately documented. Vendor and independent benchmark results are kept distinct.
