Upscale AI发布Token Fabric跨厂商芯片互联平台
英伟达投资的圣克拉拉网络初创公司 Upscale AI 发布 Token Fabric 平台，基于 UALink、ESUN 等开放标准，可将不同厂商的 GPU、自研 AI 芯片和网卡接入同一网络。据路透社报道，该平台把其自研 scale-up 交换芯片 SkyFabriX 与基于英伟达 Spectrum-X 以太网芯片的 scale-out 交换机结合，并由 SkyOS、SkyCMD 两层软件负责运行与监控，可识别瓶颈并标记可能需要更换的硬件。Upscale 称平台首批功能于第四季度推出，全面可用要到 2027 年初；CEO Barun Kar 向路透社预计明年相关收入在数千万美元级别，并可能达到低数亿美元。
随着 AI 系统规模扩大，芯片间互联速度越来越影响昂贵加速器的利用率，Upscale 想用开放标准切入这一环节。
Upscale AI, a Santa Clara networking startup backed by Nvidia, launched a platform on Thursday that lets data centres link AI chips made by different suppliers, Reuters reported.
The product, called Token Fabric, was revealed in a company announcement today. Upscale said it is built on open standards and works with graphics chips, custom AI chips, and network cards from any vendor.
Large AI systems distribute work across thousands of chips that must constantly exchange data. Networking gear links chips within a single server rack, known as scale-up. It also links racks across a building, known as scale-out. When data moves too slowly, costly chips sit idle.
