awesome. def need levels of difficulty for word puzzles against the AI; would be impossible to win otherwise :)

along those lines, you know what might be interesting is to have OSS models, including old ones, and select the model to play against (a bit like stockfish has different algos you can play chess against). This substitutes for levels of difficulty (assuming the old/small OSS models are worse, though when it comes to scrabble they might be just as good as any human in which case you would have to introduce some noise to degrade their performance
