Libraries

How to use ping98k/open_llama_3b_v2_4bit with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="ping98k/open_llama_3b_v2_4bit")

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("ping98k/open_llama_3b_v2_4bit")
model = AutoModelForCausalLM.from_pretrained("ping98k/open_llama_3b_v2_4bit")

	# Open LLaMA 3B v2 — 4-bit NF4

	4-bit quantized version of [openlm-research/open_llama_3b_v2](https://huggingface.co/openlm-research/open_llama_3b_v2) using bitsandbytes NF4, ready for QLoRA fine-tuning.

	## Quantization Details

	\| Parameter \| Value \|
	\|---\|---\|
	\| Quant method \| bitsandbytes NF4 \|
	\| Double quant \| Yes \|
	\| Compute dtype \| bfloat16 \|
	\| Model size \| ~1.93 GB \|

	## Usage

	```python
	from transformers import AutoModelForCausalLM, AutoTokenizer

	model = AutoModelForCausalLM.from_pretrained("ping98k/open_llama_3b_v2_4bit", device_map="auto")
	tokenizer = AutoTokenizer.from_pretrained("ping98k/open_llama_3b_v2_4bit")
	```

	### QLoRA Fine-tuning

	```python
	from peft import LoraConfig, get_peft_model, prepare_model_for_kbit_training

	model.gradient_checkpointing_enable()
	model = prepare_model_for_kbit_training(model)

	lora_config = LoraConfig(
	r=16,
	lora_alpha=32,
	target_modules=["q_proj", "k_proj", "v_proj", "o_proj", "gate_proj", "up_proj", "down_proj"],
	lora_dropout=0.05,
	bias="none",
