AT&T is doing exactly what OpenAI and Anthropic fear about enterprise. they’re routing 40% of employee AI usage to open models, and intend to boost it to 60-70%. > coding costs down 56% > quality dropped just 2% > 45B tokens/day btw. AT&T AI chief: open models are “just as good or better” for many tasks. they still use frontier models for the critical work but everything else gets routed to cheaper open models.
