X
XAI
An artificial intelligence company founded by Elon Musk in March 2023 with the stated mission of “understanding the true nature of the universe.” Its flagship product is **Grok**, a conversational AI integrated into Musk’s social platform X (formerly Twitter) and offered via API for developers. In March 2025, Musk merged X into xAI in an all‑stock deal valued at roughly $113 billion, giving the company direct access to X’s user base, data, and engineering resources. xAI is also building **Colossus**, a massive supercomputer cluster in Memphis designed to train next‑generation AI models using over 100,000 GPUs. While it has attracted billions in funding from Musk‑linked ventures and major investors, the company has also faced leadership turnover and public debate over Grok’s sometimes controversial outputs.
