# GreenBit LLMs

This is GreenBitAI's pretrained **low-bit** LLMs with extreme compression yet still strong performance.

Please refer to our [Github page](https://github.com/GreenBitAI/green-bit-llm) for the code to run the model and more information.

### Zero-shot Evaluation

We evaluate the zero-shot ability of low-bit quantized Qwen1.5 models using the `llm_eval` library and list the results below: 

| **Repository (Qwen Family)**      | **Avg Acc.** |  **OpenBQ**  |  **ARC-E**  |  **Winogr.**  |  **HellaS.**  |  **ARC-C**  |  **PIQA**  |  **BoolQ**  |  **RACE**   |  **ANLI-R1**  |  **ANLI-R2**  |  **ANLI-R3**  |  **WiC**  |
