The quantization process significantly reduces the memory footprint (VRAM usage) and improves inference speed, making it highly accessible for deployment on consumer-grade GPUs and limited-resource hardware, while maintaining high performance due to the nature of the NF4 method. 🔗 Original Model Source Original Model Name: mlabonne/Meta-Llama-3.1-8B-Instruct-abliterated Original Base Model: Llama 3.1 8B Instruct Original Description: A version of Llama 3.1 8B Instruct that has undergone "Abliteration" (further fine-tuning) to enhance its capabilities and alignment. ⚙️ Quantization Details Quantization Technique: NF4 (NormalFloat 4-bit) Library Used: Typically implemented using bitsandbytes via the Hugging Face transformers library. Purpose: To enable loading and running the model in 4-bit precision, drastically cutting down VRAM requirements. 🛠️ How to Use the Model (4-bit Loading) This model is intended to be used with the Hugging Face transformers library and bitsandbytes for 4-bit loading. 💻 Installation To utilize the 4-bit configuration, you must have the necessary libraries installed: ```Bash pip install torch transformers accelerate bitsandbytes ``` # Python Usage Example ```Python import torch from transformers import AutoModelForCausalLM, AutoTokenizer model_id = "ikarius/Meta-Llama-3.1-8B-Instruct-Abliterated-NF4" # 1. Load tokenizer and model tokenizer = AutoTokenizer.from_pretrained(model_id) model = AutoModelForCausalLM.from_pretrained( model_id, device_map="auto", torch_dtype=torch.bfloat16, ) # 2. Run Inference using the Instruct template messages = [ {"role": "system", "content": "You are a helpful and friendly AI assistant."}, {"role": "user", "content": "What is the main benefit of 4-bit NF4 quantization?"} ] # Apply the Llama 3.1 chat template input_ids = tokenizer.apply_chat_template(messages, return_tensors="pt").to(model.device) outputs = model.generate( input_ids, max_new_tokens=256, temperature=0.7, do_sample=True, ) print(tokenizer.decode(outputs[0], skip_special_tokens=True)) ```
