What are Large Reasoning Models? | LLMs vs. LRMs Explained

In this video, Jaydeep dives deep into Large Reasoning Models (LRMs) and explains how they differ from traditional Large Language Models (LLMs). Learn how modern AI systems “think before they answer,” using internal planning, step-by-step evaluation, reinforcement learning, and test-time compute to improve accuracy and logical coherence.
