Without Triton, or on CPU, it falls back to dequantize-and-matmul in PyTorch. ### Requirements | Package | Minimum | Verified with | | --- | --- | --- | | `torch` | 2.4 | 2.12.1+cu130 | | `transformers` | 5.8 | 5.9.0 | | `triton` | 3.0 (Linux; bundled with CUDA builds of PyTorch) | 3.7.1 | | `huggingface_hub` | 1.5 (pulled in by transformers) | 1.15.0 | ## Quantization | Field | Value | | --- | --- | | Base model | `google/gemma-4-26B-A4B-it` | | Precision | INT4, group size 128 | | Scale / zero dtype | float16 | | Calibration | wikitext2, 128 samples x 2048 | | Size | 15.8828 GB · original 51.6120 GB · 3.2x compression | ## Benchmarks Full zero-shot / few-shot results for every DASH-Q checkpoint: **[github.com/JaeminK/dashq#benchmarks](https://github.com/JaeminK/dashq#benchmarks)**
