# ReasoningQAT-Qwen3-1.7B-2bit
|
||||
|
||||
This model is a **2-bit pseudo-quantized** version of [Qwen3-1.7B](https://huggingface.co/Qwen/Qwen3-1.7B), trained with Quantization-Aware Training (QAT) for reasoning tasks.
|
||||
|
||||
## Details
|
||||
|
||||
- **Base model:** Qwen3-1.7B
|
||||
- **Quantization:** W2G128 (2-bit weights, group size 128)
|
||||
- **Format:** Pseudo-quantized (stored in FP16; weights lie on 2-bit quantization grids)
|
||||
- **Method:** ReasoningQAT — QAT combining knowledge distillation with teacher-confidence-weighted DFT loss, trained end-to-end on reasoning data
