- SpaceXAI released Grok 4.5, its first model built with AI coding startup Cursor, designed to "handle difficult, long-running" legal, finance, and coding tasks.
- Grok 4.5 is priced at roughly half the cost of competing Anthropic and OpenAI models, per SiliconANGLE and VentureBeat headlines in the coverage cluster.
- Elon Musk described Grok 4.5 as an "Opus-class model" in remarks covered by TechCrunch.
- Cursor co-developed the frontier model rather than simply routing to it, a shift from its prior role as an AI coding IDE.
- Artificial Analysis (benchmarking group) posted Grok 4.5 rankings on X the same day, per links threaded through the coverage.
- The "SpaceXAI" rebrand formally attaches SpaceX's corporate brand to the Grok chatbot, which Gizmodo flagged given Grok's prior history of generating MechaHitler imagery and deepfake porn.
Why it matters: The pricing — at roughly half the cost of Anthropic and OpenAI rivals per SiliconANGLE — reframes the frontier AI race from pure capability to price-performance. Cursor co-developed rather than routed to the model, though Forrester's headline ("Will enterprises ever choose SpaceX's Grok and Cursor?") flags the reputational hurdle Grok's history poses for enterprise adoption.
