There's a few alternatives, but SASRec is a good baseline for next-item recommendation. I'd look at BERT4Rec too. HSTU is definitely a strong step forward, but stays in the domain of ID models. HSTU also seems to rely heavily on some extra item information that SASRec does not (timestamps).
Other models include Google's TIGER model which uses a VAE to encode more information about items. Similar to how modern text-to-voice operates.
