一 |     CAPE TOWN, South Africa -- Angry protesters in Cape Town confronted the king and queen of the Netherlands on Friday as they visited a museum that traces part of their country’s 150-year involvement in slavery in South Africa.King Willem-Alexander and Queen Maxima were leaving the Slave Lodge building in central Cape Town when a small group of protesters representing South Africa's First Nations groups -- the earliest inhabitants of the region around Cape Town -- surrounded the royal couple and shouted slogans about Dutch colonizers stealing land from their ancestors.The king and queen were put into a car by security personnel and quickly driven away as some of the protesters, who were wearing traditional animal-skin dress, jostled with police.The Dutch colonized the southwestern part of South Africa in 1652 through the Dutch East India trading company. They controlled the Dutch Cape Colony for more than 150 years before British occupation. Modern-day South Africa still reflects that complicated Dutch history, most notably in the Afrikaans language, which is derived from Dutch and is widely spoken as an official language of the country, including by First Nations descendants.King Willem-Alexander and Queen Maxima made no speeches during their visit to the Slave Lodge but spent time walking through rooms where slaves were kept under Dutch colonial rule. The Slave Lodge was built in 1679, making it one of the oldest buildings in Cape Town. It was used to keep slaves -- men, women and children -- until 1811. Slavery in South Africa was abolished by the English colonizers in 1834.Garth Erasmus, a First Nations representative who accompanied the king and queen on their walk through the Slave Lodge, said their visit should serve to “exorcise some ghosts.”The Dutch East India Company established Cape Town as a settlement for trading ships to pick up supplies on their way to and from Asia. Slaves were brought to work at the colony from Asian and other African countries, but First Nations inhabitants of South Africa were also enslaved and forced off their land. Historians estimate there were nearly 40,000 slaves in the Cape Colony when slavery ended.First Nations groups have often lobbied the South African government to recognize their historic oppression. They say their story has largely been forgotten in South Africa, which instead is often defined by the apartheid era of brutal forced racial segregation that was in place between 1948 and 1994.First Nations people have a different ethnic background from South Africa's Black majority.___AP Africa news: https://apnews.com/hub/africa。

二 |      8 月 25 日消息，OpenAI 今天（25 日）晚间在 Hot Chips 大会上公布了全新推理系统 Jalapeño 的更多细节，并首次披露基准测试成绩。在 SemiAnalysis 的 InferenceX 测试中，Jalapeño 无论是单用户 token 处理量，还是每千瓦吞吐量，都超过了目前市面上的顶尖推理处理器。OpenAI 硬件负责人理查德 · 何在媒体电话会上表示：“测试结果最重要的一点，是 Jalapeño 相比目前最先进的产品实现了非常显著的性能提升。

三 | 它可以用相同的电力处理更多 AI 工作负载，同时更快给出响应。Jalapeño 既适合高效服务大量用户，也能保持很低的延迟。”Jalapeño 由 OpenAI 与博通共同开发，OpenAI 自有模型也参与了研发。OpenAI 希望把 Jalapeño 发展成一个能够延续多代的技术平台，使 AI 产品、模型、芯片和内存从一开始就协同设计。这款芯片主要负责 AI 推理，也就是让已经训练好的 AI 模型真正运行起来，完成任务或驱动 AI 智能体。OpenAI 使用 InferenceX 平台测试 Jalapeño 的推理性能，并与英伟达 GB200 和 GB300 超级芯片系统进行比较。OpenAI 称，在 GPT-OSS 120B、DeepSeek R1 和 Kimi K2.5 1T 三个模型上，Jalapeño 每瓦能够完成的 AI 工作量是对比系统的 1.5 至 1.9 倍，端到端延迟则约为对比系统的 28% 至 59%。全栈协同开发也让 OpenAI 能够直接优化推理过程中最容易拖慢速度的环节。Jalapeño 重点降低预填充和通信阶段的延迟，而这两个环节在 OpenAI 看来往往是推理性能的主要瓶颈。OpenAI 在公布测试结果的博客文章中提到，Jalapeño 从设计之初就尽量减少数据搬运和通信延迟。

四 | 生成响应时使用的 KV 缓存等模型状态可以明确存放并保留在本地，系统再根据不同推理阶段，调配合适的计算、内存和网络资源。据了解，OpenAI 计划在今年年底前先“小规模”部署 Jalapeño，2027 年再逐步扩大部署量，但没有公布明年具体会投入多少芯片。参考广告声明：文内含有的对外跳转链接（包括不限于超链接、二维码、口令等形式），用于传递更多信息，节省甄选时间，结果仅供参考，包含外链的文章均包含本声明。
