Enterprise AI leaders often assume acquiring more GPUs automatically translates to faster training and faster time to market, but at scale efficient model progress depends on coordination, observability, and operational control rather than raw compute capacity. The article identifies five misconceptions including conflating job completion with success, prioritizing speed over efficiency, and underestimating the importance of support expertise. These misunderstandings can inflate total cost of ownership and delay projects when using general-purpose cloud infrastructure instead of purpose-built AI platforms.
