How close are we to AI that can improve itself? This week on Mixture of Experts, guest host Aili McConnon is joined by Chris Hay, Sascha Brodsky and Kiyu Gabriel tackle that question and more from the latest AI headlines. First, MIT researchers demonstrate a technique that uses AI to modify another model's weights.

Do AI applications still need vector databases? Martin Keen explores RAG, AI agents, embeddings, semantic search, and context windows to explain when vector databases matter and when simpler retrieval approaches work just as well. Learn how to choose the right retrieval architecture for your workload.

Sensitive data makes AI powerful, but also risky. Jeff Crume explains five essential capabilities for using sensitive data safely across AI systems, agents, tools, and RAG pipelines. Learn how visibility, classification, governance, access controls, and evidence help secure AI-driven workflows.

The video explains how to give AI coding agents relevant repository context so they can produce code that matches existing architecture, dependencies, tests, conventions, and developer intent. It matters because a single prompt cannot capture a large codebase, while excessive context can dilute the information the agent needs.

The video explains how PyTorch’s torch.compile optimizes models through Dynamo, AOT Autograd, and Inductor, including lazy compilation, graph capture, kernel fusion, and hardware-specific code generation. It also shows why speedups vary and how graph breaks, recompilation, and incorrect benchmarking can limit performance.
