Mistral-Small-24B-Instruct-2501 (4-bit Quantized)

🚀 Overview

This repository provides a 4-bit quantized version of Mistral-Small-24B-Instruct-2501, optimized for faster inference and lower memory usage while maintaining strong performance in instruction-following tasks.

Quantization is performed using BitsAndBytes (bnb) 4-bit precision, making it feasible to run this large-scale model on consumer GPUs (such as A100 40GB, A10G, or even T4 in limited use cases).

🛠 Model Details

• Base Model: mistralai/Mistral-Small-24B-Instruct-2501
• Quantization Type: 4-bit (bnb)
• Library: transformers
• Hardware Requirements:
  • ✅ GPU: Runs on NVIDIA A100 (40GB VRAM), A10G (24GB VRAM) or higher.
  • ✅ Limited CPU Use: Possible on CPU for small inference tasks, but much slower.
• Use Cases: Advanced NLP tasks, Retrieval-Augmented Generation (RAG), chatbots, in-context learning, and fine-tuning for domain-specific applications.

📥 Usage

1️⃣ Load the Model in 4-bit Quantization

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig

MODEL_NAME = "Noorhan/mistral-24b-4bit"

# Configure quantization
quantization_config = BitsAndBytesConfig(load_in_4bit=True)

# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(MODEL_NAME)
model = AutoModelForCausalLM.from_pretrained(
    MODEL_NAME, 
    device_map="auto", 
    quantization_config=quantization_config
)

# Generate response
prompt = "Explain the concept of transformers in deep learning."
inputs = tokenizer(prompt, return_tensors="pt").to("cuda" if torch.cuda.is_available() else "cpu")
outputs = model.generate(**inputs, max_new_tokens=150)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))

📌 Limitations

• 🔸 Higher VRAM Requirements: Despite being quantized, this model still requires a high-end GPU (e.g., A100, A10G).
• 🔸 Lower Precision: 4-bit quantization slightly reduces accuracy compared to FP16.
• 🔸 Longer Sequences: Performance may degrade for very large text generations.
• 🔸 Limited CPU Inference: CPU inference is possible but significantly slower.
