The concept: A panel of AI models that debate my questions and hand me one sharp answer — running at $0, on subscriptions I already pay for. The idea I started from (Andrej Karpathy's): Different AI models — ChatGPT, Gemini, Claude — often give different answers to the same question. So instead of trusting just one, I liked Karpathy's "LLM Council" idea: ask several AIs the same question, let them read and critique each other's answers, and then have one model act as "chairman" to merge it all into a single best answer. It's like getting a second, third, and fourth opinion — then a senior expert who weighs them all and decides. How it works (3 steps): 1. I send my question to every model at once → each writes its own answer. 2. Each model reads the others' answers (anonymously) and critiques them. 3. A "chairman" model reads everything and writes one final, judged answer. What I built: My own version, running inside my AI assistant ("Brain"). Same 3-step idea — but instead of paying per use, I plugged in the AI tools I already pay for. The clever part (how anyone could do it): Karpathy's original talks to all the models through a paid service (OpenRouter) that bills you per use. I swapped that out for: - Claude — already running as my assistant; it also plays chairman. - GPT-5.5 — through the Codex command-line tool, which runs on the ChatGPT subscription I already pay for. - Gemini — through a free Google AI Studio key. A small script ties the three together. Why I made it free — the key thing I realized: Paying for ChatGPT / Gemini / Claude as apps is not the same as paying for their API (which charges per word). But the command-line agent tools (like Codex) run on the subscription I already have. So by wiring up those tools instead of calling paid APIs, my whole council runs at $0 extra — no new bills. I was already paying for these AIs; now they work together. Why I think it's worth it: - Better answers — multiple viewpoints plus cross-checking beat any single model, and catch blind spots. - $0 extra — it reuses subscriptions I already pay for. - Private & local — it runs on my own machine. - Smart chairman — Claude does the final synthesis and already knows all my context (projects, priorities). - On demand — I use it for big decisions, like planning a major project, not everyday stuff.
