Introduction

The rise of large language models (LLMs) has transformed how AI systems engage with users, allowing for more natural, contextually aware conversations. In this article, we will walk through the process of building a resource-efficient, memory-enhanced conversational AI system using Qwen, a large pre-trained language model, in conjunction with NetworkX for memory management.

We’ll cover both technical and mathematical aspects, illustrate how to optimize model use for resource-constrained environments, and explore the future potential of such systems.

The system we develop will:

  1. Use a single instance of Qwen for both response generation and evaluation to minimize resource consumption.
  2. Implement NetworkX to store conversational history in a memory graph, enabling better context handling and long-term interaction.
  3. Optimize inference using techniques like torch.no_grad() to avoid unnecessary computation, making it feasible to run complex models in environments with limited resources.

Why Resource Efficiency Matters in LLMs

LLMs like Qwen, GPT, and similar models are highly capable but demand significant computational resources, including GPU/TPU power and memory. Running multiple instances of these models in tandem…
