LLM vs vLLM: Efficiency and Scaling Explained

While a **Large Language Model (LLM)** functions as the core intelligence capable of predicting text and answering prompts, it often struggles with speed and efficiency when faced with high demand. The video explains that **vLLM** acts as a high-performance serving engine designed to solve these scaling issues through an innovative memory management system called **Paged Attention**. By treating memory like a shared library rather than reserved rooms, **vLLM** allows the same hardware to support significantly more users at a lower cost.
