IIRC yaml is easier for models than json because you don't need as much recursive syntax.

I doubt this is true anymore, if ever. Both require string escaping, which is the real hurdle. And they are heavily trained on JSON for tool calling.

I believe it could be true because I think training dataset contained a lot more yaml than json. I mean...you know how much yaml get churned out every second?
