Aligning AI with Human Intent: RLHF in Action

In this episode, we demystify how researchers teach AI models to behave helpfully and safely using Reinforcement Learning from Human Feedback (RLHF). We discuss why even very large models can generate undesired outputs and how RLHF addresses this by incorporating human preferences. You’ll learn how methods like InstructGPT were trained: first by gathering human-written demonstration responses, then by having humans rank model outputs to train a reward model, and finally using reinforcement learning (e.g. with PPO) to fine-tune the model so that it better aligns with what users want. We also talk about improvements like Constitutional AI and why aligning AI with human values is an ongoing challenge.

The Evaluation Crisis: We Do Not Know How Good Our Models Actually Are

The Evaluation Crisis: We Do Not Know How Good Our Models Actually Are

MMLU is saturated. Chatbot Arena is gameable. Public benchmarks leak into training data. The only eval that matters is the one you build yourself, on your data, for your task.

Mixture of Experts at the Edge: Running 30B Parameter Models on Your Laptop

Mixture of Experts at the Edge: Running 30B Parameter Models on Your Laptop

A 30B parameter model runs on a MacBook because only 3B parameters fire per token. Mixture of Experts splits memory cost from compute cost, and that changes everything about where AI can run.

The Agent Interoperability Problem: Why Your AI Agents Can Not Talk to Each Other

The Agent Interoperability Problem: Why Your AI Agents Can Not Talk to Each Other

90% of enterprises deploy AI agents. Only 23% scale them. The gap is interoperability. Three protocols, MCP, A2A, and ACP, are racing to build the connective tissue before the ecosystem fragments.

KV Cache Compression: The Memory Wall Nobody Talks About

KV Cache Compression: The Memory Wall Nobody Talks About

Your GPU is not compute-bound. It is memory-bound. The KV cache is eating half your inference budget, and two ICLR 2026 breakthroughs KVTC and TurboQuant are about to change the math entirely.
