Summary
This discussion addresses the inefficient storage of 512-dimensional ArcFace embeddings in PostgreSQL, where their 32-bit float size forces them into TOAST tables, doubling I/O. The proposal is to quantize these embeddings to 16-bit (HALFVEC) to keep them in-line, prompting a debate on whether 32-bit precision is truly necessary for ArcFace accuracy or if 16-bit suffices for practical applications.
