about 10sec for 1k rows ~ better than using an LLM, way more ergonomic than a classifier
game-changing for data analysis!"

For just classification, you can go much faster still by treating classification as a retrieval problem and just using embeddings. We easily hit about 20k rows/sec on CPU without doing any performance optimizations.
