Scoop: SpaceXAI launches new model, Grok 4.5

SpaceXAI has launched Grok 4.5, its most intelligent model to date and the first release since acquiring the AI coding startup Cursor. Positioned as a tool for engineering and agentic-work rather than a standard chatbot, Elon Musk describes it as maximally truth-seeking. Trained alongside Cursor, Grok 4.5 reportedly outperforms comparable models in knowledge work. Musk claims it is an Opus-class model that is faster, more token-efficient, and offers lower costs than its competitors.
