LoRA Technology Model

Model Overview

Model Name: LoRA Technology
Developed by: Abdul Sittar
Model Type: Text Generation (PEFT, LoRA)
Frameworks: Hugging Face Transformers, PEFT, Safetensors
Languages: English
License: Apache 2.0

This model is a LoRA-finetuned version of LLaMA2 7B, adapted for technology-related conversational tasks. It supports safe and efficient text generation while keeping the base model frozen and training only LoRA adapters.

Model Description

This model is intended for technology-related text generation, conversational tasks, and research purposes. It was trained using LoRA adapters on technology domain datasets and is compatible with Hugging Face Transformers for inference.

LoRA adapters: Low-rank adaptation for efficient fine-tuning
Base model: LLaMA2 7B
Model weights format: Safetensors
Intended use: Research, simulation, conversational AI for technology domain

Description:
A large-scale, empirically grounded dataset from Reddit to support agent-based social simulations. Includes:

33 technology-focused agents
14 climate-focused agents
7 COVID-related agents
Each domain includes over one million posts and comments

The dataset defines agent categories, derives inter-agent relationships, and builds directed, weighted networks reflecting real user interactions.

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_name = "AbdulSittar/llama2-lora-technology"

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained(model_name)

# Load base model with LoRA adapters
tokenizer = AutoTokenizer.from_pretrained(os.path.join(repo_path, "configs"))
model = AutoModelForCausalLM.from_pretrained(repo_path, device_map="auto")

model.eval()

# Generate text
prompt = "Latest trends in AI and machine learning:"
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=200)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
