Fine-tuning an open source embedding model to beat OpenAI's text-embedding-3-small

A fine-tuned open source embedding model can outperform OpenAI's text-embedding-3-small in accuracy at lower cost using only a handful of examples. Modal ran an experiment on the Quora duplicate-questions dataset to find how much fine-tuning data a simple question-answering use case needs, and describes how to build one on its serverless infrastructure.
