Pure quantizations of Qwen2-Math-1.5B-Instruct for qwen2.java.
In the wild, Q8_0 quantizations are fine, but Q4_0 quantizations are rarely pure e.g. the output.weights tensor is quantized with Q6_K, instead of Q4_0.
A pure Q4_0 quantization can be generated from a high precision (F32, F16, BFLOAT16) .gguf source with the quantize utility from llama.cpp as follows:
./quantize --pure ./Qwen2-1.5B-Math-Instruct-F16.gguf ./Qwen2-1.5B-Math-Instruct-Q4_0.gguf Q4_0
