xAI rebrands to SpaceXAI as it merges into SpaceX
xAI completed a rebrand to SpaceXAI with a new logo as it fully merges into SpaceX. Separately, Musk acquired gas-turbine operator APR Energy (~$1B) to power the training fleet.
Business Insider and TradingView (2026-07-06) reported that xAI has rebranded to SpaceXAI, completing its merger into SpaceX. Separately, coverage from 2026-07-14 onward reported Musk’s ~$1B acquisition of APR Energy, a mobile gas/diesel turbine operator, to supply power for xAI compute infrastructure.
The corporate identity change matters for this page’s framing (company name, ownership, entity). The API rate card was captured separately in this run and its packaging change is logged in its own entry — the merger itself produced no observed rate move.
xAI ships grok-4.5 — an intelligence-first flagship for code and general use with a 500k-token context and Feb 2026 knowledge cutoff — priced at $2.00 input / $0.50 cached / $6.00 output per 1M tokens, above the still-live grok-4.3 ($1.25 / $2.50). The consumer SuperGrok tier now runs Grok 4.5, and a new SuperGrok Lite rung appears in the plan ladder. New API billing mechanics are also published: a 20% Batch API discount, a 2x Priority Processing premium, files/collections storage ($0.025 / $0.10 per GiB/day) and a $0.05 usage-guideline violation fee.
