Bielik-Q2-Sharp: A Comparative Study of Extreme 2-bit Quantization Methods for a Polish 11B Language Model

Researchers successfully developed Bielik-Q2-Sharp, the first systematic evaluation of extreme 2-bit quantization for Polish language models, achieving near-baseline performance while significantly reducing model size. The study compared six quantization methods on an 11B parameter model, with the best variant maintaining 71.92% benchmark performance versus 72.07% baseline at just 3.26 GB.
