Description

Hello Authors,

I apologise for asking questions unrelated to an issue with the repo however, would you consider support a newer paradigm I came across whilst reading a recent paper?

It looks incredibly promising and rather well written I must say, especially when considering the performance of such a precision.
Is there anyone on the team able to give this a shot?

Research direction

The issue names no file, test, or entry point; start by locating the repository's existing quantization and numeric-precision support. Read the linked INT4 paper alongside that implementation to determine the required scope. Done would mean agreed-upon INT4 support with validation, but the issue does not define acceptance criteria.

Written by the indexing model from the issue text.
