I‘m not a game dev so I might be missing something, but this hardly looks high quality to me. The set I get is very inconsistent and lacking in any central theme, or otherwise interesting or clean design. If I regenerate one peace in isolation, say a knight, I get something completely different that looks as if you lost the knight from your set and just took replacement knights from another set at random.

The time it takes to generate a set is also significant, as a web-dev this takes for ever, and I would be very reluctant to offer this experience to my users. Doesn’t feel fluent, nor tight at all.

Plus a silly mistakes like the knights facing the wrong way, different sizes, etc. Seeing this, I certainly hope game designers (at least in online chess) will stay away from generative AI, for a while at least.
