kaitchup/Qwen2.5-1.5B-AutoRound-GPTQ-asym-4bit

Model Details

This is Qwen/Qwen2.5-1.5B quantized with AutoRound (asymmetric quantization) and serialized with the GPTQ format in 4-bit. The model has been created, tested, and evaluated by The Kaitchup.

Details on the quantization process and how to use the model here: The Best Quantization Methods to Run Llama 3.1 on Your GPU

It is possible to fine-tune an adapter on top of it following the QLoRA methodology. More about this here: QLoRA with AutoRound: Cheaper and Better LLM Fine-tuning on Your GPU

I used these hyperparameters for quantization:

bits, group_size = 4, 128

autoround = AutoRound(model, tokenizer, nsamples=512, iters=1000, low_gpu_mem_usage=False, bits=bits, group_size=group_size)

autoround.quantize()
output_dir = "./tmp_autoround"
autoround.save_quantized(output_dir, format='auto_gptq', inplace=True)
