Biden, in high-stakes visit, shows support for Israel but urges restraint_我的网站

A |     　　英伟达硬件演进正加速驶向下一站，为智能体（Agent）打造新一代算力平台。    President Joe Biden left Israel on Wednesday after a high-stakes diplomatic mission to show solidarity with the U.S. ally, but also securing Israel's commitment to allow humanitarian aid into Gaza and delivering an in-person warning to show restraint."I come to Israel with a simple message: You are not alone," Biden said as he spoke in Tel Aviv.The president compared the atrocities unleashed by Hamas to 9/11, stating Americans understand Israel's demands for justice.But he urged the nation not to be consumed by their outrage, asking officials to be deliberate with their objectives and ask the hard questions as they continue to respond to the terror attacks with airstrikes and a possible ground offensive."After 9/11, we were enraged in the United States. While we sought justice and got justice, we also made mistakes," Biden said.The remarks came off the heels of meetings with Israeli Prime Minister Benjamin Netanyahu and his war cabinet as well as first responders and other Israelis affected by the violence that's unfolded since Oct. 7.Biden achieved one key objective of the trip, as Israel agreed to allow limited quantities of aid to begin to flow into Gaza from Egypt after blocking the Rafah border crossing for more than a week, leaving virtually no options in or out of Gaza."The people of Gaza need food, water, medicine, shelter," Biden said, as he stressed Hamas "does not represent the Palestinian people" and that civilians are suffering under their rule.Biden said the understanding is that the aid will be subject to inspections to ensure it is going to civilians, not Hamas."Let me be clear: If Hamas diverts or steals the assistance, they will have demonstrated once again that they have no concern for the welfare of the Palestinian people and it will end as a practical matter, it will stop the international community from being able to provide this aid," Biden said.In addition, Biden announced $100 million in new U.S. funding for humanitarian assistance in both Gaza and the West Bank to support the more than million people displaced by the conflict.Biden stepped off Air Force One at Ben Gurion Airport in Tel Aviv at about 10:50 a.m. local time. Netanyahu was waiting for Biden and the two leaders, whose relationship spans decades, shared words before exiting in convoys.Amid Biden's words of caution and restraint -- telling Israel they, as a democracy, live by the "rule of law" not the rule of terrorists -- Netanyahu only went so far as to say Israel will continue working with the U.S. to "assure that the minimum requirements are met" as well as efforts to get hostages out of Hamas control."As we proceed in this war, Israel will do everything it can to keep civilians out of harm's way," Netanyahu said. "We've asked them and we will continue to ask them to move to safer areas."Biden's visit, a physically and politically perilous one, comes one day after a deadly blast at a Gaza hospital rocked the area.Hamas blamed the incident on the Israeli Defense Forces while Israel presented materials they say prove it was a failed rocket launch by Palestinian Islamic Jihad.Biden supported Israel's claim that militants in Gaza were responsible for the blast. He told Netanyahu that it "appears it was done by the other team, not you."Later, when asked by a reporter what made him confident the Israelis weren't behind the hospital attack, Biden said it was "the data I was shown by my Defense Department."Biden was set to visit Jordan and meet with Arab leaders there but that summit was canceled after the hospital blast.

After his meetings with Israeli officials, Biden took time to speak with first responders, families of victims and hostages and others affected by the Hamas attacks.The meetings were emotional, as one first responder recounted the atrocities inflicted on women and children.One pediatric physician who moved from New York to Israel years ago told Biden "never could have prepared" in her life for the mass casualty event she experienced following the attacks. Biden shared with her the personal story of when his wife and daughter were killed in a car accident and told her he understands physicians and nurses "make a gigantic difference."。　　当地时间8月24日，英伟达宣布，推理加速器Groq 3 LPX机架已进入全面量产阶段。英伟达高级总监Dion Harris表示，Groq机架将与Vera中央处理器和Rubin图形处理器一同部署在新型云服务商Nebius的数据中心，并将于今年晚些时候上线。　　Groq 3 LPX机架是英伟达专为Vera Rubin平台设计的推理加速扩展组件，需与 Vera Rubin NVL72 GPU主机架搭配部署——NVL72负责更广泛的训练、推理以及上下文处理，LPX专门加速输出AI生成结果（Token），主打超低延迟Token生成，两者异构协同，可大幅提升万亿参数、超长上下文智能体推理的每瓦吞吐与交互响应速度。　　英伟达此前将Vera Rubin平台定义为专为智能体AI与科学计算时代设计的机架级超级计算平台。英伟达此次将Groq 3 LPX正式推向全面生产，核心目的并不是用专用推理芯片取代GPU，而是为Vera Rubin补充传统GPU架构在低延迟Token生成方面的能力。　　相比Blackwell，Vera Rubin在智能体工作上的效率得到了极大的提升，英伟达释出多个最新测试数据（本次测试使用的基准为SemiAnalysis AgentX，该基准针对Kimi K3、MiniMax M3、GLM5.3、Qwen3.5、DeepSeek V4 Pro等各类模型）—— 　　英伟达称，在Artificial Analysis测试中，搭载Gemma 4 31B模型、100K Token上下文时，Groq 3 LPX实现每秒3400个输出Token，为该模型创下最高纪录；针对智能体编程等低延迟工作负载，其响应速度最高达到最近竞争平台的4倍。英伟达称，这种速度可以让智能体更快完成代码编写、测试、工具调用和结果验证等连续任务。　　与此同时，英伟达公布Vera Rubin NVL72在真实智能体工作负载下的新测试结果：基于SemiAnalysis的AgentX工作负载、采用DeepSeek V4 Pro模型，Vera Rubin每兆瓦（MW）吞吐量最高达到上一代GB300 NVL72的30倍，每Token成本最高降低35倍。对于运营商而言，这意味着在固定的电力和基础设施预算下，可以支持更高的交互式代理容量，或者以更低的运营成本提供相同的容量。　　英伟达强调，智能体任务不同于传统聊天对话，任务上下文会随着数百个步骤不断累积，甚至达到数十万Token。英伟达援引OpenRouter数据称，智能体AI工作负载消耗的Token数量可以达到简单聊天请求的15倍。原因在于，一个智能体可能先查询数据库，再搜索新闻和文件，调用子智能体进行分析，运行代码并反复验证，整个过程中上下文不断累积。　　近期腾讯、阿里、DeepSeek等头部厂商相继推进AI智能体产品迭代与生态布局，AI应用端发展聚焦终端场景落地与生态壁垒搭建。天风国际证券最新研报称，当前Harness加速开放迭代，前沿AI竞争正向Agent执行框架与商业化兑现深化。　　英伟达正紧随这一趋势调整硬件优化方向，当AI迈入智能体时代，AI基础设施的评价体系或将随之变化，基础设施服务商的硬件迭代重心将从追求训练更大模型，转向单位能耗有效Token产出、单位成本任务处理能力，以及智能体复杂任务的执行时延。（文章来源：财联社）。
