Just hours after Elon Musk's xAI unveiled its latest AI model, Grok 3, X almost doubled the price of its Premium+ subscription plan from $22/month to $50/month. This marks the second price hike in recent months, following a previous increase in December 2023. Grok 3 is expected to be powered by xAI’s Colossus supercomputer which reportedly houses over 1,00,000 Nvidia GPU hours for the purpose of training AI models. It was built in just over eight months. The more efficient successor to Grok 2 was reportedly trained on synthetic datasets using machine learning techniques such as reinforcement learning, according to a report by Forbes.
