I'm no expert in actual ML implementations but I was under the impression that Python (i.e Tensorflow) is actually C/C++ based under the hood. I just meant I can't imagine the V8 engine can be as performant for all that matrix math in those models.

But now that I'm looking at the actual code samples, I'm not even sure JavaScript is doing any of the actual heavy lifting? (I see you use OpenAI's embedding) so this tool is more of the glue connecting all the parts? Again, I'm out of my wheelhouse here.
