The Elon Musk-backed AI startup unveiled its latest Grok-3 artificial intelligence chatbot claimed to outperform other U.S. or Chinese competitors.

Musk says the development of Grok is driven by a need to understand the universe and is a "maximally truth-seeking" artificial intelligence.

Just how open the open-source version of Grok 2 will be is unclear, though. Sometimes, companies say open source even when they retain or hold back at least a little of their proprietary work. Still, Grok 2 is likely to have a second life in the hands of an open-source community that can tweak and experiment with it.
