Billionaire Elon Musk on Tuesday rolled out xAI's latest flagship AI model called Grok 3 with improved capabilities. On Saturday, Musk said that his rival to ChatGPT will arrive on February 18. Grok 3 has been developed with '10x' more computing power than its predecessor. The company also launched a smaller version named Grok 3-mini which is capable of faster responses to questions. Earlier this week, Musk said Grok 3 was in the final stages of development and would be released in about a week or two. However, in a recent post on X, the tech billionaire announced that the AI chatbot's scheduled launch. Touted as the “smartest AI on Earth” by Musk, 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. Reinforcement learning is said to be an effective method to reduce incorrect or imaginary responses provided by AI models, otherwise known as hallucinations. It also significantly reduces the training times of large language models (LLMs). “This might be the last time that an AI is better than Grok,” Musk had said at The World Governments Summit in Dubai recently, in praise of the upcoming LLM’s advanced capabilities. xAI’s live demo of Grok 3 comes more than a month after the disruption caused by Chinese AI startup DeepSeek. The latter’s cost-efficient reasoning model R1 is said to be on par with OpenAI’s o1 model in terms of performance, even though it was developed at just a fraction of the cost of its US competitors. Grok 2 was launched in August last year. The Grok AI chatbot can be accessed by anyone for free by signing up on X, Elon Musk’s social media platform. According to Bloomberg, xAI is expected to raise $10 billion in funding in a new round with participation from global VCs such as Sequoia Capital, Andreessen Horowitz, and Valor Equity Partners. The AI company’s valuation is likely to rise to $75 billion.
