MingZwhy/Qwen3-0.6B-W1.88-QAOPD is a 0.8 billion parameter Qwen3-based causal language model developed by MingZwhy. This model features a highly optimized quantization to 1.88 bits per weight, achieved through quantization-aware distillation and on-policy distillation. It is designed for efficient deployment and evaluation, with quantization baked directly into the model. The model demonstrates competitive performance on various benchmarks, including GSM8K, MATH-500, and HumanEval, making it suitable for resource-constrained environments requiring general language understanding and problem-solving capabilities.

Model Overview

MingZwhy/Qwen3-0.6B-W1.88-QAOPD is a highly optimized version of the Qwen3-0.6B model, developed by MingZwhy. Its primary distinguishing feature is its aggressive quantization to an effective 1.88 bits per weight, achieved through a two-stage process: quantization-aware distillation (QAD) followed by on-policy distillation (OPD). This "baked-in" quantization means the model is ready for efficient deployment and evaluation without additional quantization steps.

Key Technical Details

  • Quantization Scheme: Weights are a mixed INT1.58 / INT4 format in 256-block chunks, resulting in an effective 1.88 bits per weight. Embedding and output head use INT4, while activations are INT8. The KV cache remains 16-bit.
  • Parameter Count: 0.8 billion parameters.
  • Context Length: 32768 tokens.

Performance Highlights

Despite its aggressive quantization, the model maintains competitive performance across several benchmarks when compared to its unquantized BF16 counterpart. For instance, it achieves:

  • 39.65 on GSM8K (5-shot strict-match)
  • 35.7 on MBPP (pass@1 greedy)
  • 35.4 on HumanEval (pass@1 greedy)

Use Cases

This model is particularly well-suited for applications where computational resources and memory are constrained, but a capable language model is still required. Its efficient design makes it ideal for:

  • Edge device deployment
  • Applications requiring fast inference with a smaller footprint
  • General language understanding and generation tasks where the slight performance trade-off from quantization is acceptable for significant efficiency gains.
