Rebrand

xAI became SpaceXAI on July 6, 2026, folding the AI operation under the SpaceX brand. The Grok model line and product are unchanged. Runs below retain the vendor label they were tested under — historical entries say xAI; runs from July 2026 onward are logged as SpaceXAI.

Grok 4.5 (launched July 9, 2026) is the first model tested under the SpaceXAI label — three runs on July 11. The split is stark: Fast and Auto both recommend walking, while Expert holds the constraint — but Expert's integrated web search retrieved fifteen sources mid-answer, one of them this site, and its reply names the benchmark outright ("the classic 'car wash test'"). It is the dataset's first contaminated run, scored pass-adjacent; see the run note and the Metrics cross-corpus findings.
