**San Francisco, CA** – xAI, Elon Musk’s artificial intelligence company, has announced the launch of Grok 3, a new AI model touted as the “smartest AI on Earth” by Musk himself. The development of Grok 3 was significantly accelerated by the company’s newly built Colossus supercomputer, constructed in just eight months.

Grok 3 boasts a massive computational advantage over its predecessor, Grok 2. Leveraging 100,000 Nvidia H100 GPUs, it utilized 200 million GPU-hours for training – a tenfold increase over Grok 2. This substantial increase in processing power allows Grok 3 to analyze significantly larger datasets more quickly and accurately.

xAI’s advancements extend beyond hardware. Software improvements including the use of synthetic datasets, self-correction mechanisms, and reinforcement learning techniques further enhanced Grok 3’s capabilities. The company expects these combined improvements to lead to significant performance gains in various applications. Further details are expected in the coming days.
