Complex Systems with Patrick McKenzie (patio11)We live in a world where our civilization and daily lives depend upon institutions, infrastructure, and technological substrates that are _complicated_ but not _unknowable_. Author: Patrick McKenzie
We live in a world where our civilization and daily lives depend upon institutions, infrastructure, and technological substrates that are _complicated_ but not _unknowable_. Join Patrick McKenzie (patio11) as he discusses how decisions, technology, culture, and incentives shape our finance, technology, government, and more, with the people who built (and build) those Complex Systems.

Inference engineering and the real-world deployment of LLMs, with Philip Kiely
Episode 82
Thursday, 12 March, 2026
Patrick McKenzie (patio11) and Philip Kiely, early employee at Baseten, discuss the inference stack: the critical layer of software and hardware that sits between a model’s weights and a user’s prompt. They cover inference engineering, how intermediate layers are evolving over a technical stack that is changing every six months, and how sophisticated organizations are actually consuming LLMs beyond just writing their questions into chatbot apps.–Full transcript available here: www.complexsystemspodcast.com/inference-engineering-with-philip-kiely/–Presenting Sponsors: Mercury, Meter, & GranolaComplex Systems is presented by Mercury—radically better banking for founders. Mercury offers the best wire experience anywhere: fast, reliable, and free for domestic U.S. wires, so you can stay focused on growing your business. Apply online in minutes at mercury.com.Networking infrastructure has a way of accumulating technical debt faster than almost anything else in IT. Meter handles the full stack (wired, wireless, and cellular) as a single integrated solution: designed, deployed, and managed end-to-end so there's only one vendor to call when something goes wrong. Visit meter.com/complexsystems to book a demo. If meetings consistently leave you with hazy action items and lost context, Granola handles the transcription so you can actually participate and gives you searchable notes afterward.
