I added live translation to this site, wrote about the weird edges, then made this little playground to mess with them directly. Proper nouns, tags and markdown syntax were always coming through weird, so this helped me investigate.
TranslateGemma was one of the few models I tried. Something interesting I noticed is that each model has a different expectation of interface (fields passed in, naming of those fields and such.)
