Nice! I’ve been working on something similar and found similar results.

In my experiments, I used lots of embedding models and the results were not nearly as uniform as this curve, just FYI. I didn’t use any of the API-based models though

I also wrote about this exact comparison when using PCA and MRL to quantize static models, see: https://stephantul.github.io/blog/mrl-pca/
