    • HN 上 250 分,308 条评论,评论数比分数还多。 这条帖子讲的是 OpenTPU:一个开源 AI 加速器,标题写明是"由 AI 开发的"。AI 写软件大家已经见惯了,这回换成芯片,分量不一样。软件写错了,改一行重新跑就行;硬件错了,代价要大得多。 我是计算机工程 PhD 出身,看到这类项目,先想的是验证:AI…

    • AI 开始自己设计芯片了。 openTPU,开源 AI 加速器,13 天 290 星:架构到电路由 AI 打磨,装进 FPGA 卡真权重跑通 Qwen3 等 10 个模型,输出和模拟器逐 token 一致。 0.6B 每秒 21.6 token。机器没有缓存没有隐藏调度,每条数据搬运都是一条指令,笔记本跑模拟器就行。

    • 该来的还是来了,openTPU 整个计算机史,都在反复发明一种轮子:让工具制造自己,C 编译器用 C 写,rustc 用 Rust 写;PyPy 用 Python 写。 现在轮到 AI 了,用 AI 设计 AI 芯片。人类似乎对这种 self-hosting 有一种奇怪的执念,企图左脚踩右脚,试图把自己拽上天。 折腾了几十年,人类追求的始终是把自己从迭代循环里优化掉
