Elon Musk’s xAI Debuts Grok 3 with Colossus Supercomputer – BitRss

Elon Musk’s xAI has launched Grok 3, a new artificial intelligence (AI) model backed by a massive computing system.

A key highlight was “Colossus”, a network of 200,000 GPUs that powers Grok 3’s training. The development process took place in two stages: 122 days of training on 100,000 GPUs, followed by another 92 days as the system expanded to full capacity.

According to xAI’s announcement on X, the team noted that setting up this infrastructure was more challenging than designing the AI itself.
