What do you own in AI?
I had an interesting chat yesterday with a founder about buy versus build, about cloud-based services versus running local AI.
Think of it as the comparison between using Google Docs and Microsoft Word. One runs entirely online and in the cloud, one runs locally as an app on your device.
As with so much IT, one isn’t better than the other.
Buy alleviates the pressure of building and maintaining systems. When you fire up ChatGPT, you don’t have to think about any of the technology on the back end that makes it possible. Performance, speed, and stability are someone else’s problems. You don’t have to hire people or spend large – sometimes very large – amounts of money on technology just to serve up generative AI.
Build alleviates the worry of technology availability and data privacy. When you build your own AI using open models like Llama 4 or Mistral Small 3.2, you are in control. You don’t have to worry about waking up one day to find out Anthropic or OpenAI ran out of money and closed their doors, nor do you have to wonder just how secure your data is.
The founder I was talking to was all in on buy. They didn’t want responsibility for anything, for any amount of infrastructure. They just wanted to plug into someone else’s APIs and call it a day.
I can understand that. Certainly, the convenience is nice. But the pessimist in me wonders how smart it is to build a business – and not just tangential pieces, but your core offering – entirely on someone else’s tech stack. Once you’re locked in, the switching costs are insanely high. You also, as a business, have no business continuity. You are wholly reliant on the service provider – and if they go down or get Crowdstruck, your business is down as well.
The most sensible approach, to me, for mission critical functions is a hybrid model. Yes, make use of the best tech available through buy, but have a backup plan. Have a foundation model and at least minimal hardware or some iron at a colocation hosting provider that you could spin up quickly if the defecation broke the ventilation.
What’s different after this week, with the release of open models like Llama 4 and Mistral Small 3.2, is that build can deliver the same quality as buy – something previously not possible.
