If you don't believe the timings, I was the author of Hyperlearn https://github.com/danielhanchen/hyperlearn which makes ML faster - I also listed the papers which cite the algos.
I also used to work at NVIDIA making TSNE 2000x faster on GPUs and some other algos like Randomized SVD, sparse matrix multiplies etc.
If you have any suggestions on a more appropriate pricing strategy - I'm all ears!!
I really don't know much about pricing and the open core model, so I'm making stuff up literally.
