"Closed models are cheaper. The reason you need open models is that they give you control".

• Nvidia CEO Jensen Huang

"One of the things that people misunderstand about open models is this: yes, you can host them yourself, and you can build your own computer. But most people use computers in the cloud.

Frankly, I think closed models are cheaper. If you do not build everything yourself, you avoid the significant cost and expertise required to train, fine-tune, maintain, guardrail, evaluate, and keep the model safe. You would also need to build or obtain the computers required to host it. So, there is nothing cheap about doing all of that yourself.

The reason you need open models is that they give you control. You can adapt them for your own highly specialized use cases.

I think there is a lot of misunderstanding about closed models versus open models. We felt it was important for people to understand that there is a place for both."
