A Minecraft player has successfully created a functioning AI language model within the game, complete with the ability to engage in basic conversations.

The project, revealed in a YouTube video titled “I built ChatGPT with Minecraft redstone!”, was made by sammyuri, who is known for pushing redstone to its absolute limits. This latest build uses around five million parameters. 

That makes it tiny compared to modern AI models, which rely on billions of parameters, but within Minecraft’s blocky world, it’s a groundbreaking achievement.

Sammyuri explained that the model was first trained externally before being implemented in Minecraft using redstone circuits. That means the “learning” process didn’t take place in-game, but the process of running the trained model to generate text does happen within the Minecraft environment.

Minecraft players have been pushing the limits of redstone for years, creating working calculators, functional hard drives, and even emulators for other games. However, building a neural network of this scale is on another level.

By wiring millions of logical connections with painstaking precision, sammyuri effectively replicated how parameters in a machine learning model process data, all without mods, command blocks, or datapacks.

While conversations are slow and five million parameters only allow for the most basic responses, the build still demonstrates that machine learning can exist inside Minecraft. 

For comparison, GPT-2 had around 1.5 billion parameters, GPT-3 leapt to 175 billion, and today’s leading systems go even further. However, having such a model being produced in Minecraft remains a remarkable feat of engineering.
