LLM Council: Run Your Own Multi-Model Debate Panel with Karpathy’s 400-Line App

In a world where every AI startup asks the same question — which model should I build on? — Andrej Karpathy built a different answer: why not all of them?

LLM Council is a 23.8k-star local web app that looks like ChatGPT but works like a boardroom. Your query goes to four frontier models at once. They answer independently, then anonymously review and rank each other’s work, and finally a designated Chairman model compiles a single synthesized verdict.

It’s a 400-line “fun Saturday hack” that Karpathy calls 99% vibe coded — and it’s become one of the most discussed projects in AI, because it sits at the intersection of two seismic shifts: ensemble architectures and vibe coding.
