CAVEATS
What the source record does not assume.
01
xAI does not publish a separate text output cap on the cited model page.
02
Knowledge cutoff is left unknown because no verified value is stored in the cited official model documentation.
03
The stored Standard pricing start is anchored to xAI's May 15, 2026 migration/pricing-impact date.
