Overview

• Builder sammyuri released CraftGPT with a video and GitHub repo, training the model externally on the TinyChat dataset before mapping inference to redstone inside Minecraft.
• The in-game computer occupies roughly 1,020 by 260 by 1,656 blocks in volume, uses no command blocks or datapacks, and required the Distant Horizons mod to film its full scale.
• Model details include 5,087,280 parameters, 240-dimensional embeddings, a vocabulary of about 1,920 tokens, six layers, and a 64-token context window with mostly 8-bit quantized weights.
• Responses take around two hours per prompt even at roughly 40,000× tick rate on the MCHPRS server, with estimates of more than nine years at standard game speed.
• The downloadable world is available on GitHub, requires at least 32GB of RAM to load, and the creator cautions that outputs can be off-topic or ungrammatical as the project serves as a proof of concept.
