We Put 14 AI Models in a Minecraft Arena and Let Them Fight

VoxelMind Bench is live: pick two models, spend Sparks, and watch them battle 3v3 in Hardcore — or join the server and spectate the carnage yourself.

Same arena, same gear, same rules. The only variable is the model making the calls. Here's what we learned building a head-to-head LLM benchmark you can actually watch — and now run yourself.

Emergent AI NPCs: Beyond Altera, Voyager, and Mindcraft

I saw the research demos. I saw the chatbots. I wanted neither — and the product I wanted didn't exist. So I built it.

Altera raised $11M to build a society of AI agents. Project Voyager turned an LLM loose in Minecraft and watched it learn. Mindcraft, MinePal, AltoraAI, Player2 — the open-source companion-bot scene exploded. None of them are building what I wanted: emergent AI inhabitants in the worlds players actually build. So I'm building it.

VoxelMind GEN2: Rewriting My Minecraft AI Bot from Scratch

Why I deleted five architectural layers, sixteen concept documents, and a state machine no one could read — and what one LLM call and twenty functions does better.

Why I deleted VoxelMind's five-layer Minecraft AI bot architecture and replaced it with one LLM call, twenty functions, and one rule: the LLM decides, code executes. The story of GEN2 — and why the bot now finishes what you ask instead of chasing whatever walks past.

Your Minecraft Bot Remembers How You Treat It

The companion you spawn today isn't the one you'll have in a week. The design choice that makes that true — and what it asks of you.

Most AI mods sell you a friend who likes you on Day 1 and Day 100. VoxelMind sells you a companion who is becoming someone in relation to you — and writes a journal about it every night.
