Elon Musk and Microsoft CEO Satya Nadella discussed the upcoming launch of Grok 3.5 during a conversation at the Microsoft Build conference. Musk announced that Grok 3.5 will be launching soon and will be available to developers through Microsoft Azure. Musk described Grok 3.5 as an artificial intelligence model designed to reason from first principles, focusing on applying the fundamentals of physics across all lines of reasoning. The model aims to break down complex problems into core truths, build reasoning upward, and test conclusions against these fundamentals. According to Musk, Grok 3.5 aspires to achieve maximum truth with minimal error by using physics-based methods to guide its thinking. He emphasized the importance of real-world grounding, such as through cars and robots, for the development of safe AI systems. Developers have been encouraged to identify and report errors in Grok 3.5, with Musk stating, "Tell us where we’re wrong. We’ll fix it."
