GPT-4 takes on Minecraft ⚒️
AI researchers recently created a Minecraft bot using GPT-4 — and it’s scary good.
Voyager is what’s known as an embodied agent — an AI that can move and interact with its simulated or real environment, of its own volition.
It can accomplish tasks and explore within the game, much like a human player would, whether it’s building a base, mining iron, or building a Nether portal.
Unlike previous AI, Voyager starts with little training but has an understanding of the Minecraft world through an ‘automatic curriculum’. It uses the game state to make guesses at what would make the most sense to do at any given point.
As it learns new tasks, it adds them to its skill library. This library expands as the bot learns, and is extendable — meaning it can skill stack to perform more complex and novel behaviors over time.
Since you can’t exactly parachute GPT-4 into Minecraft and expect it to ASDW and left-click like the rest of us, the bot uses MineDojo (made by the same team behind Voyager). It’s an extra simulation layer on top of Minecraft, which lets the bot write and execute code to interact with the player.
Voyager’s traversal through the Minecraft tech tree
Voyager is more than 15x faster at advancing through the tech tree than its predecessors.
Our take: It’s impressive that LLMs like GPT-4 are enough to power independent learning behavior in open sandbox games like Minecraft. While the rules of Minecraft are bare-bones simple compared to our real-life environment, this experiment gives us a glimpse at what it might take to produce autonomous AI humanoids.

BUZZWORD OF THE DAY
NVIDIA’s AI creates 3D models from video
NVIDIA has announced a new AI model, dubbed Neuralangelo. It uses neural networks to synthesize accurate 3D models from 2D video.
Neuralangelo… like Michaelangelo. Ha, that’s a knee-slapper.
The model uses the same underlying tech as NVIDIA’s Instant NeRF, and NeRF has been around since 2020.
But compared to prior results, Neuralangelo seems to produce the highest quality outputs yet — all from video you could capture on any smartphone.

Past models have struggled to recreate fine details and textures. But here, NVIDIA has a trick up their sleeve.
The incredible level of detail is the result of a two-step process. First, the AI selects the best frames out of the input video to construct the 3D model. Then, much like a sculptor, it refines the render by sharpening the details.
At the end of the process, you have a full 3D scene or object ready to use in 3D art, video games, or as virtual twins in robotics and industrial contexts.
Our take: this may just be the best implementation of NeRF tech we’ve seen to date. Huge kudos to NVIDIA.
