00:04 Welcome to today's Tech Briefing, your daily source for the latest in technology and innovation. Today, we bring you three fascinating stories. First, we will look at SpaceX's turbulent stock market debut as its share price drops below the initial public offering price. Next, we will meet GPT-Red, an LLM super-hacker built by OpenAI to find vulnerabilities and secure its latest models. Finally, we will visit Times Square, which has transformed into a massive fan zone for the soccer World Cup. Let's get started.
欢迎收听今天的科技简报，为您带来科技与创新领域的最新动态。今天我们有三个引人入胜的故事。首先，我们将探讨 SpaceX 在股市上的动荡表现，其股价已跌破首次公开募股发行价。接着，我们将认识由 OpenAI 打造的 AI 超级黑客 GPT-Red，它专门用于寻找漏洞并保护最新模型。最后，我们将走进纽约时报广场，这里在世界杯期间已变身为巨大的球迷区。让我们开始吧。

00:34 SpaceX Stock Price Falls Below IPO Debut Level. SpaceX's share price has dropped below its initial stock market listing. The stock price fell to one hundred and thirty-two dollars on Wednesday, which is below the debut price of one hundred and thirty-five dollars. Just over a month ago, SpaceX's public debut made Elon Musk the world's first trillionaire. Since then, the stock has experienced significant volatility (波动性，易变性). At first, investors were excited to buy SpaceX shares. They saw it as an opportunity to invest in artificial intelligence. This excitement followed SpaceX's acquisition of Musk's AI startup, xAI. However, this initial market frenzy has ended. The stock price has drifted downward as the market awaits SpaceX's first public earnings report in August. While analysts say this drop is not a disaster, it shows how heavily SpaceX affects investor sentiment (情绪，态度).
SpaceX 股价跌破首次公开募股发行价。SpaceX 的股价已跌破其首次上市价格。周三股价跌至 132 美元，低于 135 美元的首发价。就在一个多月前，SpaceX 的公开亮相使埃隆·马斯克成为全球首位万亿富翁。自那以后，该股经历了剧烈的波动。起初，投资者对购买 SpaceX 股票感到非常兴奋。在 SpaceX 收购马斯克的 AI 初创公司 xAI 之后，他们将其视为投资人工智能的一个难得机会。然而，最初的市场狂热已经结束。随着市场等待 SpaceX 将在八月份公布的首次公开财报，股价逐渐走低。虽然分析师表示这一跌幅并非灾难，但它表明了 SpaceX 对投资者情绪的巨大影响。（来源：BBC Technology）

01:23 OpenAI Creates GPT-Red Super-Hacker to Secure AI Models. OpenAI has built an artificial intelligence super-hacker called GPT-Red. The company uses this model to improve its defenses against cyberattacks. The goal of GPT-Red is to automate safety evaluations known as red-teaming. In the past, human testers searched for ways to break software. However, modern AI models are very complex and act as autonomous (自主的，自治的) agents. This makes it hard for humans to find every vulnerability (弱点，易受攻击性，漏洞) (漏洞，易受攻击性). To train GPT-Red, researchers set up a self-play loop. The model attacked other AI systems, while those systems tried to defend themselves. Through this process, GPT-Red discovered new attack methods. One method is called a fake chain of thought, which tricks an LLM into accepting false data. OpenAI used GPT-Red to secure its new GPT-five point six model. The company will not release GPT-Red publicly to prevent misuse.
OpenAI 打造 AI 超级黑客 GPT-Red 以提升模型安全。OpenAI 打造了一个名为 GPT-Red 的人工智能超级黑客。该公司利用该模型来提高抵御网络攻击的防御能力。GPT-Red 的目标是使被称为“红队测试”的安全评估过程实现自动化。在过去，人类测试人员会寻找破坏软件的方法。然而，现代 AI 模型非常复杂，且可以作为自主智能体运行。这使得人类很难找到每一个漏洞。为了训练 GPT-Red，研究人员设置了一个自博弈循环。该模型攻击其他 AI 系统，而那些系统则试图进行防御。通过这一过程，GPT-Red 发现了新的攻击方法。其中一种方法被称为“伪造思维链”，它能诱骗大语言模型接受虚假数据。OpenAI 使用 GPT-Red 来保护其新的 GPT-5.6 模型。为了防止滥用，该公司不会公开释放 GPT-Red。（来源：MIT Tech Review Society）

02:25 Times Square Becomes Major World Cup Fan Zone. Times Square has become a massive unofficial fan zone for the World Cup. Hundreds of soccer fans are gathering in the plaza. They wear colorful jerseys to support teams like Brazil, Norway, and Colombia. This celebration brings a vibrant energy to the center of New York. The phenomenon is the result of a radical idea from ten years ago. In two thousand and sixteen, the city completed its project to remove cars from the plaza. This marked the tenth anniversary of the pedestrianization (步行街化，人行道化) of Times Square. When cities create space for public life, communities thrive. Local artists and tourists agree that the plaza feels alive. The area shows how prioritizing (优先考虑，确定优先顺序) people can transform a busy street into a place for celebration.
纽约时报广场成为世界杯主要球迷区。时报广场已成为世界杯的一个巨大的非官方球迷区。成百上千的足球迷聚集在广场上。他们穿着五颜六色的球衣来支持巴西、挪威和哥伦比亚等球队。这场庆祝活动为纽约中心带去了充满活力的能量。这一现象是十年前一个激进想法的结果。在 2016 年，该市完成了从广场上清除车辆的项目。这标志着时报广场步行街化改造十周年。当城市为公共生活创造空间时，社区就会蓬勃发展。当地艺术家和游客都认为广场显得充满活力。该地区展示了优先考虑行人如何将一条繁忙的街道变成一个庆祝的场所。（来源：Fast Company Co.Design）
