Impressed to see that it doesn't necessarily get all the sample images provided on the site right - obviously would be tempting in a tool like this to pick images there that are guaranteed to be correct, but for example the image of a bicycle wheel disc brake gets classified as a 'bicycle chain', and the typewriter as a 'computer keyboard'. Good to demonstrate the failure modes, rather than attempt to project complete infallibility.

I also like the secondary classification it does of people, looking for a 'notable person' match.
