Grok also carries the smallest run count of the five engines at 7, so its shares rest on fewer answers than the others.","window_to":"2026-09-05","review_status":"generated","generated_at":"2026-09-05T16:57:59.660Z"},{"id":"9f91edb1-4fd8-4693-9f3c-aa9b307f6cde","section":"what_moved","body_md":"This is the first measured window on record for the category.
