Nvidia-backed Upscale AI launches Token Fabric to link chips from rival vendors
Upscale AI, a Santa Clara networking startup backed by Nvidia, launched Token Fabric, a platform built on open standards such as UALink and Ethernet for Scale-Up Networking that can put GPUs, custom AI chips and network cards from different suppliers on the same network. Reuters reported the platform combines Upscale's own scale-up switch chip, SkyFabriX, with scale-out switches based on Nvidia's Spectrum-X Ethernet chips, plus SkyOS and SkyCMD software that runs and monitors the network and can flag bottlenecks and hardware needing replacement. Upscale said the first part ships in the fourth quarter with the rest rolling out through 2027, and general availability in early 2027; CEO Barun Kar told Reuters he expects revenue in the tens of millions of dollars next year, possibly reaching the low hundreds of millions.
Chip-to-chip networking is a growing bottleneck as AI systems scale, so a vendor-neutral alternative to proprietary links is worth watching.
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.
