Fast, all-purpose topic modeling for Python: 20+ models (LDA, STM, CTM, DMR, keyATM, BERTopic, ETM, ...) behind one NumPy-native interface on a parallel Rust core, with shared diagnostics and reproducible fits.

A small showcase for topic modeling with the tmtoolkit Python package. I use a corpus of articles from the German online news website Spiegel Online (SPON) to create a topic model for before and during the COVID-19 pandemic.
