Rivian 的人工智能重心不仅仅是追逐特斯拉
Rivian 首席执行官 RJ Scaringe 在帕洛阿尔托举行的一次活动中宣布，将转向开发自己的自动驾驶人工智能芯片。此举旨在比 Waymo 和特斯拉等竞争对手在更短的时间内实现 4 级自动驾驶。Rivian 正在大力投资集成方法，包括专有硅芯片、先进传感器技术和现实世界数据收集，以增强其自主能力。该公司的免提驾驶功能现已在美国和加拿大 350 万英里的道路上使用，作为名为 Autonomy Plus 的付费套餐的一部分。尽管分析师和影响者在活动中做出了积极反应，但 Rivian 仍面临法律责任问题和投资者怀疑等挑战。
如果读者喜欢人工智能生成的小说怎么办？
Chakrabarty 使用包括 Tony Tulathimutte 在内的 30 位作者的著作对 GPT-4o 进行了微调，发现人工智能生成的文本可以有效地模仿人类的写作风格，常常愚弄读者。研究显示，在将原创作品与人工智能模仿作品进行比较时，大约三分之二的情况下，研究生更喜欢人工智能输出的质量。这引起了人们对文学和版权问题上潜在滥用的担忧。莉迪亚·戴维斯 (Lydia Davis) 等一些作者承认人工智能有能力生成令人信服的文本，而朱诺·迪亚兹 (Junot Díaz) 和西格丽德·努涅斯 (Sigrid Nunez) 等其他作者则批评人工智能生成的文本在地理和文体上的不准确性。
人工智能带来的新工作：到 2027 年，印度的人工智能劳动力将增加一倍
人工智能正在通过消除数据科学、分析和管理领域的旧角色并产生新角色来改变就业市场。印度政府报告称，约有 865,000 人注册或接受了与人工智能和大数据分析等新兴技术相关的课程培训。电子和信息技术部启动了 FutureSkills PRIME 计划，旨在对 IT 专业人员进行先进技术的再培训。超过 185 万名考生在该平台注册，超过 33 万人完成了课程。行业预测预计，到 2027 年，印度的人工智能劳动力数量将增加一倍。政府通过各种人工智能计划和国家职业服务门户网站的职业机会来支持初创企业和年轻人。
专家警告人工智能正在减少你的大脑工作
麻省理工学院的研究人员使用脑电图记录大脑活动，而参与者则使用 ChatGPT 等生成式人工智能工具来完成撰写论文等任务。研究发现，依赖人工智能的人大脑认知处理能力下降，难以回忆文章内容，这引发了人们对批判性思维和解决问题技能可能受到损害的担忧。卡内基梅隆大学和微软的另一项研究强调，过度依赖人工智能可能会降低员工解决问题的能力。对学童的调查还表明，人工智能的使用对他们的学术技能产生了负面影响。然而，一些研究人员认为，如果使用得当，人工智能可以增强学习和技能发展。人们呼吁在广泛采用人工智能工具之前，对人工智能工具对教育的长期影响进行更多研究。

消息人士称，独家人工智能芯片公司 Cerebras 将在推迟后申请美国 IPO
人工智能芯片制造商 Cerebras Systems 正准备最快下周在美国申请 IPO，目标是在 2026 年第二季度上市。该公司此前于 10 月份撤回了 IPO 申请，此前该公司筹集了超过 10 亿美元资金，估值达到 80 亿美元。此后，Cerebras 获得了美国外国投资委员会 (CFIUS) 的许可，而之前的投资者和客户阿布扎比科技集团 G42 不再被列为投资者。尽管市场波动，2025 年美国 IPO 活动依然强劲。
Stocks rise on Wall Street as AI stocks turn higher again Stocks on Wall Street rose for a second consecutive day, with technology stocks driving gains, particularly those focused on artificial intelligence. The S&P 500 and Nasdaq closed higher despite early-week setbacks. Nvidia led the market upward, gaining 3.9%. Oracle saw a significant increase after signing agreements to form a new TikTok U.S. joint venture. Consumer sentiment showed slight improvement but remains below levels from December 2024. Inflation数据显示意外降温，但市场仍保持在自九月以来的交易区间内。美联储维持谨慎立场，预计将在一月份继续保持利率不变。日经225指数因日本央行提高基准利率而上涨1%。 Updated [hour]:[minute] [AMPM] [timezone], [monthFull] [day], [year] Â NEW YORK (AP) â Stocks gained ground on Wall Street Friday for a second straight day, wiping away losses from earlier in the week. Technology stocks were once again the main force behind the marketâs broader moves, especially companies with a focus on artificial intelligence. Both the S&P 500 and the Nasdaq closed out the week with gains, despite several stumbles early this week. The S&P 500 rose 59.74 points, or 0.9%, to 6,834.50. It notched a 0.1% gain for the week. The Dow Jones Industrial Average rose 183.04 points, or 0.4%, to 48,134.89. The technology-heavy Nasdaq made the biggest move. It rose 301.26 points, or 1.3%, to 23,307.62 and notched a 0.5% gain for the week. Nvidia was the biggest force driving the market higher, with a 3.9% gain. Broadcom jumped 3.2%. The technology sector has been fueling Wall Street throughout the year as companies with outsized values like Nvidia exert more pressure on markets. But, those pricey stock values have come under more scrutiny from investors wondering whether they are justifiable. Oracle rose 6.6% on news that it, along with two other investors, had signed agreements to form a new TikTok U.S. joint ventur e. Oracle, Silver Lake and MGX each get a 15% share in the popular social video platform, ensuring that it can continue operating in the U.S. Company earnings and how companies are performing amid tariffs and inflation were a key focus for Wall Street. Nike slumped 10.5%, as the impact from tariffs overshadowed an otherwise strong quarterly profit report. Frozen potato maker Lamb Weston fell 25.9%, despite also beating Wall Streetâs profit and revenue forecasts. Winnebago Industries jumped 8.4% after turning in profits and revenue for its latest quarter that easily beat analystsâ estimates. Homebuilders fell following a report showing that home sales slowed from a year earlier for the first time since May. KB Home fell 8.5%. A survey from the University of Michigan showed that consumer sentiment in December improved slightly from November, but is deeply diminished from a year ago. âDespite some signs of improvement to close out the year, sentiment remains nearly 30% below December 2024, as pocketbook issues continue to dominate consumer views of the economy,â wrote Surveys of Consumers Director, Joanne Hsu. Consumer confidence has been weakening throughout the year as persistent inflation squeezes consumers. The job market is also slowing while retail sales weaken. Businesses and consumers are also worrying about the continued impact of a wide-ranging U.S.-led trade war that has targeted key partners including China and Canada. The latest inflation update on Thursday revealed a surprise cooling of prices in November. The Labor Department reported that its consumer price index rose 2.7%. But economists quickly warned that those numbers were suspect because theyâd been delayed and likely distorted by the 43-day federal shutdown. âThe wave of economic data did little to provide clarity for investors this week, keeping the market in the trading range it has been in since September,â said. Mark Hackett, chief market strategist at Nationwide, in a note to investors. Inflation is still above the Federal Reserveâs 2% target. The central bank cut its benchmark interest rate at its most recent meeting. It has been concerned about the slowing job market hurting the economy. But cutting interest rates could add more fuel to inflation, which could also stunt economic growth. The Fed has maintained a cautious stance about interest rate policy heading into 2026 and Wall Street is mostly betting that it will hold steady on rates at its next meeting in January. Treasury yields rose in the bond market. The yield on the 10-year Treasury rose to 4.15% from 4.11% late Thursday. Japanese stocks rose after the Bank of Japan raised its benchmark interest rate to its highest level in 30 years. In Tokyo, the Nikkei 225 gained 1%, leading the rise across Asiaâs key markets. Markets in Europe also gained ground. ââ AP Business Writer Matt Ott contributed.
我们请了四位人工智能编码代理来重建扫雷——结果是爆炸性的
ArsTechnica 测试了四种主要的 AI 编码模型（OpenAI 的 Codex、Anthropic 的 Claude Code、Google 的 Gemini CLI 和 Mistral Vibe），看看它们是否能够重新创建经典游戏扫雷，并添加音效、移动支持和独特的游戏元素等功能。每个模型都是根据实现、演示、有趣的功能、编码效率和整体性能来评判的。OpenAI 的 Codex 由于包含先进的和弦功能和精美的界面而成为表现最好的，其次是 Anthropic 的 Claude Code 因其简洁的美观和快速的生成时间。Mistral Vibe 表现出了希望，但缺乏关键功能和速度，而 Google 的 Gemini CLI 未能生成可玩的游戏。这些测试凸显了人工智能在编码任务中的潜力，而交互式人工协助对于获得最佳结果仍然至关重要。
Known 使用语音 AI 帮助您进行更多面对面约会 |TechCrunch
Celeste Amadon 和 Asher Allen 创建了一款名为 Known 的人工智能驱动的约会应用程序，该应用程序使用语音驱动的入门来收集详细的用户信息，以提高匹配质量。该初创公司在旧金山的测试阶段发现，将介绍转化为实际日期的成功率高达 80%，明显高于典型的基于滑动的应用程序。Known 已从投资者那里筹集了 970 万美元，这是 Forerunner 的首笔约会应用投资。人工智能系统可以动态跟进，并根据用户喜好提供量身定制的餐厅推荐。已知计划在进一步测试后于明年初推出。
特斯拉的专利申请显示创新速度放缓并转向人工智能/自动驾驶
对特斯拉过去十年专利申请的分析显示，特斯拉的专利申请出现了向人工智能硬件和软件的重大转变，表明汽车相关创新有所下降。虽然汽车销售仍占大部分收入，但特斯拉对自动驾驶和机器人技术的关注度大幅提高，目前只有不到 10% 的专利被归类为“汽车”。这一转变引发了人们对特斯拉作为一家汽车制造商的未来增长潜力和作为一家专注于人工智能的科技公司的前景的质疑。
