xAI – Frontier models: Memphis Colossus computing cluster scale-out and Grok assistant.
xAI can build massive gigawatt-scale clusters (like Colossus in Memphis) faster than standard hyperscalers by bypassing traditional utility grids and corporate bureaucracies.
Directs xAI's compute-first strategy, Memphis cluster scale-out, and engineering integration with Tesla and SpaceX.
xAI launches Grok 4, a major foundation upgrade incorporating advanced real-world visual logic and deep real-time tool execution, trained on the expanded Memphis 200k B200/H100 cluster.
Grok experiences a massive wave of downloads and press coverage. xAI leverages Elon Musk's distribution through the X platform to rapidly scale user adoption in the consumer space.
xAI officially launches Grok 3, demonstrating breakthrough mathematical logic and long-horizon planning performance, trained on the 100k liquid-cooled Colossus cluster in Memphis.
xAI shipped a standalone consumer app and deepened Grok's integration with the X platform.
