As someone spending time in the realms of product in the fintech industry and machine learning at the University of Toronto, I’ve spent a lot of time thinking about the intersection of AI research and its real-world applications. So, when I signed up for UC Berkeley’s LLM Agents MOOC, I was excited to dig into how large language models (LLMs) are evolving into agents that can reason, act, and collaborate in increasingly complex ways.
This course turned out to be one of the most engaging learning experiences I’ve had recently. The lectures were packed with insights into the theory and practice of LLMs, and the course Discord server gave the whole thing a collaborative, human touch. Talking through lecture concepts, asking questions, and seeing other students’ perspectives made the learning experience way more dynamic and social than I expected for an online course.
Shunyu Yao’s lecture on ReAct frameworks was definitely a favourite. It broke down how agents can unify reasoning across tasks like question answering, symbolic reasoning, and tool use. It struck me that while these systems are powerful, they’re still far from perfect and require a lot of manual design for domain-specific applications. As someone working on user-facing products, it made me think about how important it is to design systems that balance flexibility with reliability, especially for non-technical end users.
Another standout lecture came from Burak Gokturk, who discussed trends in enterprise AI. One of the big takeaways was how AI is shifting from dense, single-task models toward sparse, multi-modal ones that can handle everything from text to images to video. This resonates with what I see in the tech world—companies are racing to build generalist systems that can do it all, but the real challenge lies in making them scalable, safe, and cost-effective.
The course didn’t just stick to theory—it dove into real challenges like debugging monolithic models, building modular AI systems, and even designing agents for software development. One thing that stuck with me from Lecture 5 on compound AI systems was how modularity can make these systems more transparent and controllable. That’s something I think we need more of in the real world, especially as these models become more integrated into workflows that affect actual people.
But honestly, what made the course special wasn’t just the lectures—it was the format. The asynchronous structure meant I could fit it around my schedule, and the Discord server made it feel like I wasn’t learning in isolation. I appreciated how accessible everything was, from the well-organized slides to the recorded sessions.
Looking back, the biggest thing I’ve taken away is the importance of bridging research and application. Whether you’re debugging a compound AI system or designing a user-friendly product, it’s all about balancing ambition with responsibility. For now, I’m excited to apply what I’ve learned—both in my studies and in building better tools for the future.
