Ask HN: Why does devin.ai's website set my Mac's fan off?

I just found it ironic that the website for an relatively expensive AI agent for software development makes my GPU Process CPU metric (according to Chrome's Task Manager) reach over 1000.

I forget the last website that was similarly strong in resource demand.

https://devin.ai/

Considering that it's making such a strong demand of the GPU process makes me suspect animation or graphics, but I'd love some clarification by someone with greater insight.
