In the grand finale of "All Things LLM," hosts Alex and Ben look ahead to the bleeding edge—and reflect on the ultimate question for AI: can we ever truly understand how these models think?

Inside this episode:

• The rise of reasoning models: Discover why the next leap for AI isn’t just bigger models, but smarter thinking. Explore how OpenAI’s o1 and DeepSeek-R1 represent a paradigm shift, moving from brute-force “pre-train and scale” to dynamic, inference-time reasoning. Learn how these new models, designed for test-time compute, “think longer” to tackle complex challenges in math, code, and logic.
• How reasoning emerges: Uncover the latest approaches—like inference-time scaling, majority voting, and the power of reinforcement learning—that let models break down problems step by step, creating explicit “chains of thought” and more reliable answers.
• Interpretability and the black box: Go deep into the science of Mechanistic Interpretability (MI). Find out how tools like classifier probes, activation patching, and sparse auto-encoders (SAEs) are helping researchers reverse-engineer the inner workings of LLMs, from Golden Gate Bridge neurons to features for deception, coding errors, and more.
• Ongoing debates: What’s the endgame for interpretability? Can we achieve a complete, human-understandable model, or is it as hard as explaining the brain? What’s the path to building both powerful and truly safe AI?

Perfect for listeners searching for:

• Reasoning models vs. LLMs
• Test-time compute and chain-of-thought
• Mechanistic Interpretability (MI) in AI
• Opening the black box of AI
• Sparse auto-encoders and activation patching
• Scaling laws beyond pre-training
• AI safety and alignment
• DeepSeek, OpenAI o1, Claude 3 research

Wrap-up:
Join us for a rich, forward-looking discussion at the intersection of science, engineering, and philosophy—where progress is rapid, safety is paramount, and interpretability is the new frontier. Whether you’re a developer, researcher, or lifelong learner, this episode brings you full circle on the state and future of LLMs.
