# SpaceXAI Rebrands and Releases Grok 4.5 > Source: > Published: 2026-07-08 20:45:44+00:00 For practitioners, consolidation of AI teams into capital-rich industrial groups often shifts pricing, deployment, and compute-access dynamics that affect inference costs and procurement choices. Reported events: Business Insider and Yahoo report that xAI has rebranded to **SpaceXAI**, updating its account handle and logo after SpaceX's June IPO; Business Insider notes Elon Musk said in May that xAI would be folded into SpaceX. Gizmodo reports that **`Grok 4.5`** is the first model release under the SpaceXAI name and quotes Musk calling it "an Opus-class model, but faster, more token-efficient, and lower cost." Gizmodo also reports claimed pricing of **$2 per 1M input tokens** and **$6 per 1M output tokens** for `Grok 4.5`, and compares those rates to Anthropic's `Opus 4.8` and Anthropic's `Fable` prices. Gizmodo reports `Grok 4.5` lags top models on many benchmarks despite the efficiency claims. Business Insider and Yahoo additionally report SpaceX disclosed **$12.7 billion** in AI capital expenditures for 2025 and said it aims to deploy "AI compute satellites" as early as 2028.
