That aside- a very small model that takes text and outputs structured json according to a spec is nice. It let's you turn natural language into a user action. For example, command palettes could benefit from this.
If you can do a tiny bit of planning (todo) and chain actions, it seems reasonable that you could traverse a rich state space to achieve some goal on behalf of a user.
Games could use something like it for free form dialog while stool enforcing predefined narrative graphs etc.
I'm sure you could come up with more. It's a fuzzy function.
