Upscale AI has launched Token Fabric, a platform designed to connect AI chips from different suppliers in data-centre networks. Its pitch is to give operators more choice over chip suppliers without leaving those chips waiting on data to move.

What happened
Token Fabric combines Upscale’s SkyFabriX scale-up switch chip with scale-out switches based on Nvidia’s Spectrum-X Ethernet chips. The platform also includes SkyOS and SkyCMD software to run and monitor the network. The Next Web, reporting Reuters’ account of the launch, says the system is designed to identify bottlenecks and flag hardware that may need replacing.
Upscale says the platform uses open standards including UALink and Ethernet for Scale-Up Networking, or ESUN, to connect accelerators from different vendors. The first part is due in the fourth quarter, with general availability expected in early 2027 and other components rolling out in stages.
Why it matters
Large AI systems rely on chips exchanging data quickly. If networking holds that traffic up, expensive accelerators can sit idle. Token Fabric’s proposed mix of switch hardware and network software is an attempt to make those links less dependent on one supplier’s ecosystem.
That could give cloud providers and neoclouds more flexibility when building AI infrastructure. It is a product launch, not evidence yet that mixed-vendor networks will be straightforward to deploy or deliver the promised performance.
Our read
The useful idea is interoperability at the point where AI systems can waste a great deal of money waiting for their next batch of data. Token Fabric is an ambitious attempt to join the scale-up and scale-out sides of that problem, rather than offering one more chip and wishing the network well.
The practical test will be whether customers can combine rival hardware without adding a new layer of complexity. The staged rollout leaves time for that answer to emerge.
What to watch
- Whether the first Token Fabric components arrive in the fourth quarter as planned.
- Which chip vendors and cloud operators take part in early access.
- Whether real deployments show that mixed-vendor links reduce bottlenecks without creating new ones.
Discussion spark: Should AI data-centre buyers prioritise open, mixed-vendor networks even if they are harder to manage, or is a single supplier’s integrated system worth the lock-in?
