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].

Core Insights - Musk announced the release of Grok 4, claiming it is the first AI capable of solving complex engineering problems that cannot be found in the internet or books [4] Group 1: Product Features - Grok 4 is a reasoning model that supports both text and image inputs, function calls, and structured outputs [2] - It has a context window of 256K tokens, which is lower than Gemini 2.5 Pro's 1M tokens but higher than Claude 4 Sonnet and Opus (200K tokens) and R1 0528 (128K tokens) [2] - The pricing for Grok 4 is similar to Grok 3, at $3/15 per million input/output tokens, with cache input tokens priced at $0.75 per million [2] Group 2: Performance Metrics - Grok 4 outputs 75 tokens per second, which is slower than o3 (188 tokens/s), Gemini 2.5 Pro (142 tokens/s), and Claude 4 Sonnet Thinking (85 tokens/s), but faster than Claude 4 Opus Thinking (66 tokens/s) [3] - It ranks first in various benchmarks such as Humanity's Last Exam, MMLU-Pro, AIME 2024, AIME 25, and GPQA, outperforming OpenAI's o3 and Google's Gemini 2.5 Pro [3] Group 3: Future Developments - xAI announced upcoming products, including an AI programming model set to launch in August, a multimodal agent in September, and a video generation model in October [5]

RT Artificial Analysis (@ArtificialAnlys)xAI gave us early access to Grok 4 - and the results are in. Grok 4 is now the leading AI model.We have run our full suite of benchmarks and Grok 4 achieves an Artificial Analysis Intelligence Index of 73, ahead of OpenAI o3 at 70, Google Gemini 2.5 Pro at 70, Anthropic Claude 4 Opus at 64 and DeepSeek R1 0528 at 68. Full results breakdown below.This is the first time that @elonmusk's @xai has the lead the AI frontier. Grok 3 scored competitively with the latest mode ...

金十数据5月29日讯，今天凌晨，全球著名开源大模型平台DeepSeek开源了R1最新0528版本。DeepSeek 目前没有对该版本进行任何说明，又只是"悄悄"地开放了模型。估计很快会放出模型卡介绍更多功能。 但已经有网友迫不及待的对新版R1进行测试，在著名代码测试平台Live CodeBench中显示，其性能可以 媲美OpenAI最新的o3模型高版本。也有网友对新版R1的风格进行了测试，几乎和OpenAI的o3差不多。 （AIGC开放社区） DeepSeek开源新版R1，媲美OpenAI最高o3模型 | Rank | Model | Pass@1 ↓ | Easy-Pass@1 | Medium-P | | --- | --- | --- | --- | --- | | 1 | 04-Mini (High) | 80.2 | 99.1 | 80 | | 2 | 03 (High) | 75.8 | 99.1 | | | 3 | 04-Mini (Medium) | 74.2 | 98.2 | 8 | | 4 | DeepSeek-R1-0528 | 73.1 | 98.7 | 8 | | 5 | 03-Mi ...
