Episode Details

Million-token context windows sound impressive, but the real magic happens in the invisible layer between you and the model API. This episode unpacks the AI Agent Harness — the middleware that handles context compression, sliding windows, summarization pipelines, and memory management. We explore how tools like Open WebUI and LangChain automate these decisions, why the distinction between model features and middleware matters, and how users develop superstitions about model behavior based on harness choices they never see. If you've ever wondered why an AI seems to "remember" or "forget" things, the answer is probably in the harness.
