It makes sense that the standard governing AI accelerators should release an update less than a year after its first iteration.

Ultra Accelerator Link (UALink) 1.0 was released in April 2025, and the UALink consortium just released a major update to the specification that addresses in-network compute, chiplet definition, and manageability. These additions will support the deployment of UALink solutions in multi-workload environments and help improve UALink technology efficiency, performance for AI workloads, and ease of implementation.

In a briefing with EE Times, Kurtis Bowman, UALink consortium board chair, said the evolution of UALink reflects the rapid growth of accelerators in data centers, where memory bandwidth is critical to performance.
