Research paper questions effectiveness of post-training quantization for text embedders

By PulseAugur Editorial · [2 sources] ·

A new research paper published on arXiv investigates the effectiveness of post-training quantization (PTQ) techniques for text embedders. The study found that common heuristics for PTQ, such as protecting the embedding table and allocating bits based on module sensitivity, do not reliably transfer to retrieval embedders. The research quantizes models across various bit widths and group sizes, revealing that module sensitivity becomes family-dependent at lower bit widths and that a simple reconstruction proxy is less reliable for selecting tensors to protect.
