A Comparative Performance Analysis of Locally Deployed Large Language Models Through a Retrieval-Augmented Generation Educational Assistant Application for Textual Data Extraction
This analysis details the development and benchmarking of a Retrieval-Augmented Generation (RAG)-based chatbot for university course catalogs. It compares several open-source Large Language Models (LLMs) to optimize for accuracy, computational efficiency, and real-time applicability in academic advising, providing critical insights for educational AI deployment.
Executive Impact: Key Findings for Your Enterprise
Our research reveals the practical trade-offs between LLM size, response accuracy, and operational latency in real-world educational AI applications. Optimizing RAG configurations is crucial for delivering reliable, context-aware information, directly enhancing student support and advisor efficiency.

The study rigorously compared four open-source LLMs: Llama 3:8B, Llama 3.1:8B, Llama 3.2:3.21B, and Phi-4:14.7B. Key findings indicate a clear trade-off: larger models like Phi-4:14.7B achieve superior relevance (avg 4.68) but incur significantly higher latency (avg 37.94s). Conversely, Llama 3.2:3.21B offers the fastest responses (avg 7.17s), making it suitable for time-sensitive, low-complexity queries, albeit with slightly lower relevance (avg 3.88). Llama 3.1:8B provides a strong balance, benefiting from its extended context length for multi-turn queries while maintaining sub-20s response times. This highlights the critical need to balance accuracy and efficiency based on specific application requirements.
Retrieval-Augmented Generation (RAG) is central to this system, mitigating LLM hallucinations by anchoring responses in verifiable, external data. The RAG pipeline involves: Document Ingestion & Preprocessing, Embedding & Indexing (using mxbai-embed-large and ChromaDB), Query Processing & Retrieval (k-NN semantic search), Prompt Augmentation, and Response Generation. This ensures factual accuracy for academic advising queries, dynamically adapting to diverse student needs without relying on brittle rule-based systems or extensive manual FAQs. The framework's adaptability allows it to be customized for domain-specific knowledge bases.
Deploying generative AI in academic advising necessitates addressing critical ethical considerations. Accuracy and Student Trust are paramount, as misinformation can lead to academic setbacks. The system emphasizes clear communication of AI limitations and encourages verification with human advisors for critical decisions. Human Oversight and Transparency are key; RAG-based systems serve as advisory tools, not standalone decision-makers. Furthermore, Privacy and Data Use are vital, requiring adherence to FERPA and institutional policies, ensuring anonymized and authorized datasets for any future fine-tuning or data retention.
