YAML for model responce

[KSemenenko]

I have a theory than YAML will take less tokens than JSON,
If so, is it possible that using this format in requests will make them cheaper?
And according to my survey, json sometimes turns out to be invalid.

From my own experience, the models have an much easier time outputting YAML because it doesn't need to worry about closing tags and escaping characters like quotes. I also agree that YAML would use fewer tokens.
