AT&T and Microsoft scale trillion-token workloads with Microsoft Foundry and AMD

First-of-its-kind telecom AI deployment Telecommunications organizations are increasingly looking to AI to help teams navigate highly specialized domains, but generic models often lack the industry-specific knowledge needed to understand telecom networks, standards, and operations. To address that gap, AT&T created their Open Telco (OTel) models, the next generation of telecom-focused AI designed to bring deeper telecommunications expertise into AI systems. Building OTel2.0 required more than training a large language model, it reflected a broader issue many organizations face: how to build domain-specific AI systems at scale while balancing cost, performance, and operational complexity. Cost management quickly became a key consideration. To continue advancing telecom-focused AI, AT&T needed a platform capable of supporting OTel2.0 development at an entirely new scale. Where teams previously had to own and manage deployments, infrastructure, and the associated operational overhead, Foundry Managed Compute provided a more streamlined way to access dedicated graphics processing unit (GPU) capacity. …
