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]   NEW YORK (AP) — 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 market’s 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 Street’s profit and revenue forecasts. Winnebago Industries jumped 8.4% after turning in profits and revenue for its latest quarter that easily beat analysts’ 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. “Despite 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,” 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 they’d been delayed and likely distorted by the 43-day federal shutdown. “The 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,” said. Mark Hackett, chief market strategist at Nationwide, in a note to investors. Inflation is still above the Federal Reserve’s 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 Asia’s key markets. Markets in Europe also gained ground. —— 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。
