求职者用AI写简历,HR用AI筛简历,陷入「无人录用」死循环
量子位· 2025-09-09 11:03
Core Viewpoint - The use of AI in both resume writing and screening has not improved job search efficiency, leading to a cycle where applicants and HR are increasingly frustrated with the process [20][41]. Group 1: Job Market Dynamics - Many job seekers are using AI tools to create resumes, yet this has not translated into better job opportunities [20]. - Companies are also employing AI to filter resumes, resulting in a high volume of applications being screened out without human review [28][41]. - The job market has become a closed loop where both applicants and HR are caught in a cycle of dissatisfaction [29][30]. Group 2: Applicant Experiences - A case study of a recent graduate, Harris, illustrates the struggle; he applied for 200 positions and received no offers, with many applications going unanswered [13][14]. - Another example is Martine, a lawyer's assistant with 10 years of experience, who faced similar challenges despite multiple interviews [17][18]. - Applicants report various reasons for rejection, including lack of qualifications, keyword mismatches, and even being overqualified [4][38]. Group 3: HR Perspectives - HR professionals express frustration over the influx of similar AI-generated resumes, which they find unoriginal and lacking personal touch [33][35]. - There is a sentiment among HR that AI-generated applications do not reflect genuine effort, making them easier to dismiss [35]. - The use of AI in the hiring process has led to a disconnect between applicants and employers, complicating the recruitment landscape [41].
奥特曼:点名表扬两个波兰人,OpenAI还没遇到过他们解决不了的问题
量子位· 2025-09-09 08:06
梦晨 发自 凹非寺 量子位 | 公众号 QbitAI 奥特曼点名表扬了两个波兰人。 没有他们,OpenAI就不是今天的样子。 他们在OpenAI的贡献从Dota项目大规模扩展了强化学习,到领导了GPT-4的预训练,还与 Ilya和Lukasz共同推动了导致推理突破的最初想 法。 当然,奥特曼对他们如此高评价或许还有另一个原因: 在2023年OpenAI内乱事件中, 他俩也是带头站出来宣布辞职 ,要追随奥特曼离开的。 从高中同窗到OpenAI重聚 故事还要从波兰的一所学校说起, 格丁尼亚第三高中。 他们是OpenAI首席科学家 Jakub Pachocki 以及头衔为"Technical Fellow"的 Szymon Sidor 。 △ 左:Jakub Pachocki,右:Szymon Sidor 两人不仅是 波兰老乡 ,而且是 高中同学 ,读博时分别选择了计算机科学和机器人,后来又在OpenAI重聚。 在ChatGPT风靡全球、每天服务数亿用户的今天,奥特曼感慨大多数人永远不会想到背后那些付出心血的人,这两位波兰科学家,正是其中 的关键角色。 先说Pachocki(以下简称 帕哥 )这边。 15岁的时候, ...

OpenAI新幻觉论文惹争议!GPT-5拉胯是测试基准有问题??
量子位· 2025-09-08 09:00
Core Viewpoint - OpenAI's recent paper discusses the phenomenon of "hallucination" in language models, attributing it to the current training and evaluation processes that favor guessing over admitting uncertainty [2][14]. Group 1: Definition and Implications of Hallucination - OpenAI defines hallucination as the generation of seemingly reasonable but incorrect answers by language models [8]. - The paper highlights that even simple questions can lead to hallucinations, where models provide multiple incorrect answers confidently [10][11]. - The current evaluation methods incentivize models to guess rather than express uncertainty, leading to a culture of "confidently wrong" responses [15][17]. Group 2: Evaluation Metrics and Model Performance - The paper suggests that the evaluation metrics should be redesigned to penalize guessing more than abstaining from answering, and to reward appropriate expressions of uncertainty [22]. - GPT-5, according to the paper, has a higher abstention rate (52%) compared to previous models, indicating it is less likely to guess [6]. - The performance of GPT-5 is framed as a consequence of the flawed evaluation metrics rather than a failure of the model itself [6][19]. Group 3: Community Reactions and Philosophical Discussions - The paper has sparked discussions on whether all outputs from large language models are hallucinations and the implications of this for understanding model capabilities [26][27]. - Some argue that the nature of language and its relationship to truth complicates the notion of hallucination, as language does not equate to truth [34][35]. - The limitations of statistical models are also highlighted, suggesting that errors in predictions are expected outcomes rather than failures [39][40]. Group 4: Practical Applications and Concerns - There are concerns about the practical implications of models that might choose to say "I don't know" instead of providing a plausible answer, which could affect user experience [45]. - The discussion includes the potential utility of hallucinations in creative writing, where a degree of fictional output is acceptable [43][44]. - The balance between providing confident answers and admitting uncertainty remains a critical point of debate among users and developers [46].

量子位· 2025-09-08 07:00
Core Viewpoint - xAI, founded by Elon Musk, is developing its own inference chip, codenamed X1, using TSMC's 3nm process, with mass production expected in Q3 2026, starting with 300,000 units [1][2]. Group 1: xAI's Chip Development - xAI has been facing a "chip shortage" and plans to raise $12 billion to purchase NVIDIA chips [2]. - The goal is to achieve a computing power equivalent to 50 million H100 chips within five years, significantly more than the 100,000 H100 chips in the world's strongest AI cluster [3][5]. - The move to self-develop chips is seen as a necessary step to meet ambitious targets and reduce reliance on suppliers like NVIDIA and AMD [6][7]. Group 2: Competitive Landscape - Other major tech companies, including Google, Meta, and OpenAI, are also pursuing self-developed chips, indicating a trend in the industry [8][24]. - OpenAI is reportedly working with Broadcom on a custom AI inference chip, expected to be produced in 2026, which mirrors xAI's strategy [21][22]. - xAI's establishment of an office in Seattle is viewed as a strategic move to compete directly with other AI firms already present in the area [14][18]. Group 3: Tesla's Chip Initiatives - Tesla is also developing its own inference chips, with recent updates indicating a focus on the AI5 and AI6 chips, which will support Tesla's AI and autonomous driving efforts [26][34]. - The AI5 chip is positioned as a transitional chip, while the AI6 is intended to be the core of Tesla's future AI ecosystem, with production handled by TSMC and Samsung respectively [34][35]. - The shift from a dual-chip strategy to a single-chip focus reflects a commitment to enhancing chip performance and efficiency [31][33].
Meta超级智能实验室首篇论文:重新定义RAG
量子位· 2025-09-08 07:00
Core Insights - Meta's Superintelligence Lab has introduced a new decoding framework called REFRAG, which redefines Retrieval-Augmented Generation (RAG) and can accelerate Time-to-First-Token (TTFT) by up to 30 times [1][24]. Group 1: RAG Overview - RAG enhances large language models (LLMs) by retrieving relevant information from external knowledge bases to improve the accuracy and timeliness of responses [6]. - The current RAG model faces challenges in balancing reasoning efficiency and information volume, leading to increased computational complexity and delays in generating responses [7][8]. Group 2: REFRAG Framework - REFRAG optimizes the way LLMs process external knowledge through a three-step process: Compress, Sense, and Expand [14]. - The compression step involves using a lightweight encoder to convert long reference texts into compact vector representations, significantly reducing input sequence length and computational load [17]. - The sensing step employs a reinforcement learning-based strategy network to identify and retain key information from the compressed representations [20][21]. - The expansion step combines compressed representations with essential original text blocks to provide LLMs with optimized input for generating responses [23]. Group 3: Performance Improvements - REFRAG has demonstrated a maximum acceleration of 30.85 times in TTFT and a 3.75 times improvement compared to previous advanced methods [24]. - The framework maintains performance accuracy in perplexity and various downstream tasks, such as question answering and summarization, without any loss in performance [27]. - The compression technique allows the model to handle more information within the same computational budget, effectively expanding the context window by 16 times, which can enhance performance in certain tasks [28]. - REFRAG is applicable not only to RAG but also to multi-turn dialogues and long document summarization tasks, addressing core efficiency issues in processing long-context information [29].
