I also looked at how AI generated code could be previewed inside a code editor. Sharing some quick sketches here, along with feedback from Taylor:

Hey! I'll give you my 2c. Feasibility of this will depend on the tech powering the code editor. It is typically possible though to bold, italic, etc within these. vscode does this through themes as part of their support for syntax highlighting. Determining what gets italicized can differ between themes. I'm sure there's a default set of things in vscode, but I'm not sure what they are. Overall I think italicizing as the only marker of AI generated code may not be enough. It would need a background highlight or something like a slug imo. (edited)
