Google has sentencepiece but its written in C++ and java side requires jni and its not that much portable So we have added opensource SentencePiece4J thats all pure java and more portable. You can checkout all code : (https://github.com/eix128/SentencePiece4J)](https://github.com/eix128/SentencePiece4J)
We have added maven support also: https://mvnrepository.com/artifact/io.github.eix128/sentencepiece4j
IF anyone interested in including spring ai project we try our best to support...
