- GPU Architecture for LLM Inference: Memory, Bandwidth and Hardware Explained · 20 minGPUs are the engines powering every AI conversation you've ever had — but what's actually happening inside those chips when an LLM generates a response? Understanding GPU…
- KV Cache Fundamentals · 24 minThe unsung hero of every LLM conversation you've ever had? A clever optimization called the KV cache. Self-attention is computationally brutal — every token attending to every…
- AI Inference 101 · 28 minEveryone talks about training the model — the data, the compute, the alignment magic. But what happens after the weights are frozen and millions of users start hammering it with…
- Mechanistic Interpretability: How Researchers Try To See Inside Models · 29 minAs AI systems grow more powerful, they grow harder to understand — and that tradeoff has never mattered more. Most interpretability tricks give us approximations from the…
- LLM As A Judge · 30 minLabeled data is expensive, slow, and painfully hard to come by — and when you're trying to evaluate whether an AI workflow is actually doing what you want, the problem gets even…

- Better Know a Benchmark: Humanity's Last Exam · 23 minHumanity's Last Exam was designed with a bold premise: questions that human experts can answer, but AI models can't. Originally dubbed "Humanity's Last Stand," this benchmark is…
- A Scientific Deep Dive into Overconfident LLMs: Interview with Kaitlyn Zhou (Cornell) · 34 minWhen a language model tells you it's absolutely certain, is it actually more likely to be right? Kaitlyn Zhou's research says: not necessarily — sometimes confident phrasing…
- Reasoning Models: When LLMs Went Beyond Fancy Autocomplete · 25 minReasoning models don't just answer your question — they *think out loud* first. In this episode we dig into the class of AI models that generate intermediate chains of thought…
- Distillation, or, How to Steal a Model · 24 minThis week we’re covering model distillation: the technique of using a large "teacher" model's outputs to train a smaller, cheaper "student" model that mimics it. They cover the…
- Invisible LLM Failures and AI Fluency with Chris Potts (Stanford) · 41 minWhat happens when a Stanford linguistics professor turns his attention to AI chatbots — and the surprisingly invisible ways humans misunderstand them? Chris Potts joins the show…
- Interviewing the Linear Digressions Agents (The Agents Season, Episode 11) · 38 minAfter a five-year hiatus, the podcast that burned out partly over the tedium of writing episode descriptions is back — and using AI agents to handle exactly that task. The…
- Agent Economics (The Agents Season, Episode 10) · 24 minWhat if building more highways made your commute *slower*? That's the paradox at the heart of AI agent economics: even as per-token inference costs have plummeted dramatically…
- Agent Trust, Oversight and Control (The Agents Season, Episode 9) · 26 minCapabilities get all the attention when it comes to AI agents — but what happens when a highly capable agent makes a bad decision in the real world? Trust, oversight, and control…
- Many Agents, Many Problems (The Agents Season, Episode 8) · 28 minWhether you work best solo or thrive in a team, you know collaboration is complicated — and it turns out AI agents face the same tensions. This episode dives into multi-agent…
- How Do You Evaluate An AI Agent? (The Agents Season, Episode 7) · 32 minKnowing when an AI agent has failed sounds straightforward — until it isn't. Agents have a frustrating habit of finishing confidently while quietly doing the wrong thing, or…
- AI Agent Failure Modes (The Agents Season, Episode 6) · 33 minDespite what the marketing hype might suggest, AI agents are far from infallible — and if you've ever actually used one, you already know this. Today's episode dives deep into…
- Agentic Planning (The Agents Season, Episode 5) · 24 minWhen tackling a complex, multi-step task, even the smartest AI agent can fail without a solid game plan. This episode dives into the research around agentic planning — how agents…
- Memory Management for AI Agents (The Agents Season, Episode 4) · 25 minContext windows are powerful — but finite, and surprisingly easy to overwhelm. When an AI agent is tackling a long, complex task, the information it needs has to fit inside that…
- Lost in the Middle (The Agents Season, Episode 3) · 20 minJust like a memorable talk lives or dies by its opening and closing, LLMs have a surprisingly similar quirk: they pay close attention to what's at the beginning and end of their…
- ReAct and Tool Usage (The Agents Season, Episode 2) · 24 minBefore 2022, there was a wall between AI and the real world — models could reason impressively, but couldn't look anything up, run code, or check whether anything they said was…
- What's an AI Agent? And Why's That Hard to Define? (The Agents Season, Episode 1) · 19 minAI agents are having a moment — and unpacking them properly takes more than a single conversation. This episode kicks off a dedicated multi-part season exploring AI agents from…
- Unfaithful Chain of Thought · 25 minWhat's actually happening when an LLM "thinks out loud"? Research on human decision-making suggests that much of the reasoning we believe drives our choices is actually post hoc…
- Benchmark Bank Heist · 13 minWhat if an AI decided the smartest way to pass its test was to find the answer key? That's exactly what Anthropic's Claude Opus did when faced with a benchmark evaluation —…
- Benchmarking AI Models · 30 minHow do you know if a new AI model is actually better than the last one? It turns out answering that question is a lot messier than it sounds. This week we dig into the world of…
