xAI Confirms Open-Source Release Of Grok 3

Elon Musk confirmed on X that xAI will open-source its Grok 3 model, fulfilling an August 2025 pledge and following a late-January GitHub release of its Grok-powered recommendation algorithm. Grok 3, launched in February 2025 and trained on roughly 200,000 GPUs in xAI’s Memphis data center, is described as an order-of-magnitude improvement and underpins features across X. The move aligns with a transparency strategy amid regulatory scrutiny and a $3.4 billion chip-financing deal.
