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…

Data: FactSet ; Chart: Matt Phillips/Axios SpaceX jumped another 4.8% Tuesday, enabling Elon Musk's space launch/satellite services/AI/social media conglomerate to leapfrog Amazon.com in market value. - In just its first two full days of trading, SpaceX has added roughly $537 billion to push its market value to $2.659 trillion, according to FactSet data. - That puts it ahead of Amazon.com, which was valued at $2.646 trillion at Tuesday's close. Why it matters: The gain underscores the extraordinary power Musk's mastery of the stock market gives him. - Essentially, the surge in market value provides SpaceX with hundreds of billions of dollars out of thin air, which it can then use to remarkable operational advantage. Case in point:…
