# Han2Han

A demo of [`cadazar/han2han-rl`](https://huggingface.co/cadazar/han2han-rl), a
169M-parameter encoder-decoder that converts Korean text between Hangul and
mixed Hangul-Hanja script in both directions. The model card describes what to
expect, including the errors that remain when restoring Hanja.

Each message is converted on its own, with greedy decoding and the token budget
the model card recommends. Lines longer than 300 characters are split at
sentence boundaries and converted piece by piece.
