Core Viewpoint - The article discusses the launch of Grok 4, an AI model developed by xAI, which is claimed to be the most powerful AI model globally, surpassing existing top models in various benchmarks [1][2]. Group 1: Grok 4 Performance - Grok 4 achieved a perfect score in the AIME25 mathematics competition and scored 26.9% in the "Human Last Exam" (HLE), which consists of 2,500 expert-level questions across multiple disciplines [1]. - The AI analysis index for Grok 4 reached 73, making it the top-ranked model, ahead of OpenAI's o3 and Google's Gemini 2.5 Pro, both at 70 [2]. - Grok 4 set a historical high score of 24% in the HLE, surpassing the previous record of 21% held by Google's Gemini 2.5 Pro [5]. Group 2: Development and Training - Grok 4's training volume is 100 times that of Grok 2, with over 10 times the computational power invested in the reinforcement learning phase compared to other models [5]. - The subscription fee for Grok 4 is set at $30 per month, while a more advanced version, Grok 4 Heavy, costs $300 per month [5]. Group 3: Financial Aspects and Funding - xAI has raised a total of $10 billion in its latest funding round, which includes $5 billion in debt and $5 billion in equity, bringing its total funding since 2024 to $22 billion [10]. - Despite the substantial funding, xAI faces high operational costs, reportedly spending $1 billion per month, with only $4 billion in cash remaining as of March 2025 [11]. - xAI's projected revenue for 2025 is $5 billion, significantly lower than OpenAI's expected $12.7 billion, indicating a lag in commercial progress [11]. Group 4: Future Outlook - xAI aims to leverage the vast data from X to train its models, potentially avoiding high data costs, with a goal to achieve profitability by 2027 [12]. - Upcoming releases include a programming model in August, a multi-agent model in September, and a video generation model in October, although previous delays raise questions about these timelines [12].
