Evaluation

The model was evaluated on HumanEval and HumanEval+ benchmark with the Neural Magic fork of the EvalPlus implementation of HumanEval+ and the vLLM engine, using the following commands:

python evalplus/codegen/generate.py --model nm-testing/Qwen3-Coder-30B-A3B-Instruct-W4A16-awq --bs 16 --temperature 0.2 --n_samples 50 --root "./results" --dataset humaneval --backend vllm --dtype auto 

python evalplus/evalplus/sanitize.py results/humaneval/nm-testing--Qwen3-Coder-30B-A3B-Instruct-W4A16-awq_vllm_temp_0.2
