FWIW the {} syntax in Unsloth's to_sharegpt is Python's standard str.format() / f-string placeholder convention. It's likely just a path of least resistance: "Hello {name}".format(name=value) is idiomatic Python, and using the same delimiter means column substitution reads naturally to any Python developer and requires zero custom parser logic — just .format(**row) or str.format_map() against a dict of column names.

thats how you format input data for unsloth/lora style training.

google writes a paper about how llms are introducing drift to our language and its semantics, and they sign it using a tag intended to be imbibed by something like unsloth.

so this is like.. the smoker talking about how smoking fucks people up, then lighting up a cigarette at the end of the monologue?
