Granite-3.1-2B-Reasoning-4bit (Quantized for Efficiency)

Model Overview

This is a 4-bit quantized version of ruslanmv/granite-3.1-2b-Reasoning, which is fine-tuned from ibm-granite/granite-3.1-2b-instruct. The quantization allows for significantly reduced memory usage while maintaining strong reasoning capabilities.

Developed by: ruslanmv
License: Apache 2.0
Base Model: ibm-granite/granite-3.1-2b-instruct
Fine-tuned for: Logical reasoning, structured problem-solving, long-context tasks
Quantized with: bitsandbytes (4-bit precision)
Supported Languages: English
Tensor Type: BF16
Parameter Size: 2.53B params

Why Use the Quantized Version?

This 4-bit quantized model is ideal for users who require fast inference speeds and reduced memory usage while still benefiting from Granite's advanced reasoning capabilities.

✅ 2x Faster Training compared to standard methods
✅ Lower VRAM usage, ideal for consumer GPUs
✅ Optimized for inference, making it more efficient for deployment

Installation & Usage

To run the quantized model, install the required dependencies:

bash

pip install torch torchvision torchaudio
pip install accelerate
pip install transformers
pip install bitsandbytes

Running the Model

Use the following Python snippet to load and generate text with the 4-bit quantized model:

python

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
import bitsandbytes as bnb

device = "cuda" if torch.cuda.is_available() else "cpu"
model_path = "ruslanmv/granite-3.1-2b-Reasoning-4bit"

tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(
    model_path, 
    device_map="auto",
    load_in_4bit=True,  # Load model in 4-bit precision
    quantization_config=bnb.QuantizationConfig(llm_int8_threshold=6.0)
)
model.eval()

input_text = "Can you explain the difference between inductive and deductive reasoning?"
input_tokens = tokenizer(input_text, return_tensors="pt").to(device)

output = model.generate(**input_tokens, max_length=4000)
output_text = tokenizer.batch_decode(output)

print(output_text)

Intended Use

Granite-3.1-2B-Reasoning-4bit is designed for tasks requiring structured reasoning, including:

Logical and analytical problem-solving
Text-based reasoning tasks
Mathematical and symbolic reasoning
Advanced instruction-following

This model is particularly useful for users needing a lightweight, high-performance version of Granite-3.1-2B-Reasoning without sacrificing too much accuracy.
