Doug Turnbull has a neat solution. Tell the model to output tags without any details of the existing vocabulary, then use vector embeddings against the existing corpus to find the concrete tags that are closest to the ones the model imagined might fit!

Kitchen & Tabletop / Kitchen Organization / Food Storage & Canisters
School Furniture and Supplies / School Furniture / School Chairs & Seating / Stackable Chairs
Baby & Kids / Toddler & Kids Bedroom Furniture / Kids Beds
