A lot has happened this month, especially with the releases of new flagship models like GPT-4.5 and Llama 4. But you might have noticed that reactions to these releases were relatively muted. Why? One reason could be that GPT-4.5 and Llama 4 remain conventional models, which means they were trained without explicit reinforcement learning for reasoning. However, OpenAI's recent release of the o3 reasoning model demonstrates there is still considerable room for improvement when investing compute strategically, specifically via reinforcement learning methods tailored for reasoning tasks. While reasoning alone isn't a silver bullet, it reliably improves model accuracy and problem-solving capabilities on challenging tasks (so far). And I expect reasoning-focused post-training to become standard practice in future LLM pipelines. So, in this article, let's explore the latest developments in reasoning via reinforcement learning.

Q-learning is a model-free reinforcement learning algorithm that enables agents to learn optimal actions through interaction with their environment.

Teaching a Car to Cross a Mountain using Policy Gradient Methods in Python: A Mathematical Deep Dive into Reinforcement Learning

Reinforcement learning (RL) is a fascinating field of AI focused on training agents to make decisions by interacting with an environment and learning from rewards and penalties. RL differs from supervised learning because it involves doing rather than learning from a static dataset. Let’s delve into the core principles of RL and explore its applications in game playing, robot control, and resource management. Principles of Reinforcement Learning Agent and Environment: In RL, the agent is the learner or decision-maker interacting with the environment. The environment provides context to the agent, affecting its decisions and providing feedback through rewards or penalties.

This article was written by Steeve Huang.   Reinforcement Learning (RL) refers to a kind of Machine Learning method in which the agent receives a delayed reward in the next time step to evaluate its previous action. It was mostly used in games (e.g. Atari, Mario), with performance on par with or even exceeding humans. Recently,… Read More »Introduction to Various Reinforcement Learning Algorithms
