The second has similar problems: it has tuning knobs with missing winding posts, then five strings becoming four at the bridge. It also has a pickup under the fretboard.
Are these considered good capability examples?
It is pretty good with some easier assets that I suspect there's lots of samples of (and we're comparing to other generative models, not to what humans make. Humans probably still win by a good margin). But when moving out of obvious assets that we could easily find, I'm not seeing good performance at all. Probably a lot can be done with heavy prompt engineering but that just makes things more complicated to evaluate.
