Concept
2-bit
2-bit means representing each numeric value using only 2 bits, giving 2^2 = 4 distinct levels. It sits at the aggressive end of the quantization spectrum, well below the more common int8 and int4 formats.
The rest of “2-bit” is a premium feature: every concept in the library gets a precise, practitioner-focused write-up like this one, cross-linked straight from the paper summaries that use it.
