Probably the most useful advice I can give you if you run an ad agency, a marketing company, a production studio, or anything in that space. Hear me out. I’ve spent a decade talking to teams about this and watching the same mistake play out again and again. Don’t, and I repeat, please don’t, try to build some sort of internal tool that connects different models and becomes the only way your team accesses frontier models. I’ve seen dozens of companies go down this path. On paper, it sounds smart, differentiated, strategic, “we own the stack.” In reality, it almost never works out that way. It becomes a constant drain: slow to build, expensive to maintain, and always a step behind whatever new models, features, and workflows are emerging. It’s the same mistake companies made when they tried to build their own cloud. It felt strategic. It wasn’t. Focus on what you are good at.
