Quantization of open LLMs offers speedups but lacks consistent accuracy reporting

A recent analysis of mid-size open LLMs reveals that quantization techniques, while promising speedups, often come with a trade-off in accuracy that is not consistently reported across all models and benchmarks. The study found that 4-bit weight quantization can roughly double decoding speed for small batches, but this performance gain diminishes significantly as batch sizes increase and models become compute-bound. For these larger batches, FP8 quantization shows potential for continued speed improvements, though comprehensive data on accuracy trade-offs for various quantization methods and hardware like AMD and Intel Gaudi remains scarce.
