Great idea! There is a lot of potential! The biggest challenge for me is not just reading the most important papers but finding them. You already did the heavy lifting by downloading papers and computing the gpt3 embedding. With that you can build an index and add searching. You could cluster papers into categories to let the user browse. You could umap the papers etc. In the long term I would want it to be comprehensive and include all papers. In terms of costs, perhaps you can partner with arxiv directly. They should be interested to use your project...
