OpenAI 首款自研芯片 Jalapeño 性能首秀：DeepSeek R1 每瓦 AI 吞吐量是 GB300 的 1.7 倍_我的网站

A |     （ECNS） -- A 4,285-meter canal carved into a karst cliff in southwest China’s Chongqing has become a social media sensation, attracting photographers and hikers to Qianjin village in Wulong district.    Nearly 1,000 meters of the canal runs flush against a precipice hundreds of meters high, with spring water still trickling through its channels.    Villagers began hacking the waterway out of solid rock in 1999 using chisels and hammers, completing it three years later to bring water and electricity to mountain communities.        From lifeline to hiking destination    As modern irrigation improved, the canal’s role faded, but its dramatic setting has turned it into a magnet for outdoor enthusiasts.      "The trickling sound of spring water runs on one side and a green canyon on the other. It was well worth the trip," said Liu Zhengchun, a hiking enthusiast from Chongqing, who came with friends after watching videos shared by bloggers on social media.    He noted that the narrowest section of the canal is barely wide enough for one person to pass by bending forward, and that the chisel marks left by the builders remain clearly visible on the rock face.    A waterfall near a hydropower station along the route has also become a highlight.    Builder-turned-guardian    Builder Li Wufeng, now in his 60s, continues to maintain the canal and volunteers as a safety monitor as visitor numbers grow.     "In the past, I was basically the only person walking on the canal," Li said. "Now more and more young people come to explore, hike and take photos. On peak days, I can run into more than 200 visitors."    Local government eyes tourism development    As the site's popularity grows, authorities are paying increasing attention to outdoor safety and ecological protection. Local officials are planning a loop-shaped scenic area that integrates sightseeing, experiential activities and leisure, with supporting facilities including a parking structure, a visitor center, cliffside plank roads and a glass observation deck.    The goal is to give the cliffside canal, once a hard-won lifeline for a mountain village, a renewed purpose in the era of cultural tourism.                    。

B |      8 月 26 日消息，OpenAI 昨日（8 月 25 日）发布博文，展示其首款自研 Jalapeño 芯片，并表示无论是单用户 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。在官方博文中，OpenAI 使用半导体研究公司 SemiAnalysis 开发的公共基准测试工具 InferenceX，通过 GPT-OSS 120B、DeepSeek R1 670B 和 Kimi K2.5 1T 三款模型测试。

C | 测试显示对比市面上领先的 AI 系统（GB200 和 GB300），每瓦能够完成的 AI 吞吐量是对比系统的 1.5 至 1.9 倍，端到端延迟则约为对比系统的 28% 至 59%。混合 Token 吞吐量与现有 AI 加速器的最快解码速度对比3 款模型峰值单用户解码吞吐量各平台最佳运行点的混合 Token 峰值吞吐量OpenAI 表示，Jalapeno 在运行 GPT-OSS 120B 时，每千瓦的峰值吞吐量比 GB200 系统高出约 1.9 倍。在 DeepSeek R1 上，它的每瓦性能比 GB300 高出约 1.7 倍；在 Kimi K2.5 上，它的每瓦性能比 GB300 高出约 1.5 倍。Jalapeno 的额定功率为 700 瓦，但在测试工作负载期间，其持续功耗保持在 550 瓦或以下。附上相关图片如下：延伸阅读Jalapeño 是 OpenAI 首款自研 AI 推理芯片，由 OpenAI 与博通（Broadcom）合作开发，台积电采用 3nm 制程代工制造，于 2026 年 6 月 24 日首次对外展示。该芯片是一颗 ASIC（专用集成电路），采用 systolic array（脉动阵列）架构，配备 HBM 高带宽内存，专为大语言模型推理场景设计，不用于模型训练。芯片及配套服务器系统均不会对外销售，仅供 OpenAI 内部使用，旨在降低自身 GPU 采购和算力运营成本。OpenAI 硬件负责人 Richard Ho 领导了该芯片的研发，他此前在 Google 工作近九年，是 Cloud TPU 项目的核心工程师。Jalapeño 从架构设计到完成流片仅耗时约 9 个月，OpenAI 称这是高性能先进半导体领域有史以来最快的 ASIC 开发周期之一。OpenAI 自身的 AI 模型也深度参与了芯片设计流程，帮助加速设计优化。

D | 目前第二代 Jalapeño 芯片已进入后期开发阶段，预计未来数月内完成流片；第三代芯片也已启动概念设计。OpenAI 计划于 2026 年年底前小规模部署 Jalapeño，2027 年逐步扩大部署规模。需要注意的是，Jalapeño 此次测试对比的对象为英伟达 GB200 和 GB300 系统，尚未与英伟达最新一代 Vera Rubin 芯片进行对比测试。OpenAI 表示英伟达仍是其重要合作伙伴，未来将持续采用多供应商策略以满足庞大的算力需求。相关阅读：。
