Pull the (AI) Lever, Kronk!

Matt and Kris welcome back Bill Kennedy who's been working on Kronk, AI tooling in Go. They go through what Kronk (and it's dependent library Yzma) is, the power of running models locally, and how they see coding agents and LLMs shaping the future of the industry.

We've got supporter content, of course! This week that includes the message-caching trick that turns seconds into thirty milliseconds, why hybrid models quietly wreck the KV cache, Bill's "thirty billion knobs" explainer for dense versus mixture-of-experts models, why demo day is destroying engineering teams, and the stealth-startup math nobody says out loud. Not a supporter yet? Fix that today by heading over to https://fallthrough.fm/subscribe where you'll get not only extra content but also higher quality audio. Sign up today!
