ines ae2ad5becc Remove charts from model direcory and add speed benchmarks
With speed benchmarks, charts ended up taking up too much space – and they were mostly data porn and not particularly useful anyways. Instead, we might add a "Compare" page that fetches all models and lets the user compare two or more models in terms of accuracy, speed etc.
