AT&T Inc.

AT&T is an aggressive AI adopter that has deployed generative AI at enterprise scale, with over 100,000 employees using its proprietary 'Ask AT&T' platform built on OpenAI/ChatGPT, Meta LLaMA 2, and other LLMs, supported by partnerships with Microsoft and NVIDIA. The company publicly emphasizes a 'human in the loop' governance model, formal AI guiding principles, and a security-driven SDLC for AI validation. AT&T has undergone significant workforce reductions — over 115,000 employees in five years and ongoing 2025 restructuring — and industry reporting draws a circumstantial link between AI-driven automation and job displacement, though the company primarily attributes cuts to broader cost-reduction programs. Public disclosures are detailed and broadly consistent with internal evidence, though the relationship between AI cost savings and headcount reductions is not fully disaggregated in official statements.
