xAI

xAI is the AI company Elon Musk founded in 2023 and the team behind Grok. Its large investment in the Colossus supercomputer in Memphis, fast training cycles, and aggressive release cadence have all drawn attention. Tight integration with the X platform gives it a distinctive edge on real-time data. Outside the OpenAI / Anthropic / Google DeepMind triad it is the most recent major addition to the frontier stage.
