xAI is the artificial intelligence company founded by Elon Musk in 2023. Its about page states a mission to understand the universe, and the company is the maker of the Grok family of AI assistant models.
As of June 2026, xAI develops and distributes Grok through its own apps and API and via integration with the X platform. The company is associated with large-scale compute investment and a fast model-release cadence, with the Grok 4 generation current on its site at the verification date.
Why business readers should care: xAI is a well-funded frontier-AI entrant tied to a major social platform and a high-profile founder, so its trajectory affects competitive dynamics even for organizations that do not yet use Grok directly.
