Elon Musk's SpaceXAI is launching Grok 4.5, its smartest model yet, and its first release since going public and acquiring the AI coding startup Cursor. Why it matters: The new model is being pitched as a coding and agentic-work tool, more than a consumer-facing chatbot — one that Musk says is "maximally truth-seeking" compared to its competitors. Zoom in: The company says Grok 4.5, trained alongside Cursor, outperforms comparable models on engineering and knowledge work. - "It is an Opus-class model, but faster, more token-efficient and lower cost," wrote Musk in a post on X , referencing what was until recently Anthropic's top model family. - A chart accompanying the announcement says the model outperforms Opus 4.8 on several key…
