AI Beats Minecraft: Four Google Agents Defeat the Ender Dragon

Four AI agents from Google DeepMind have beaten Minecraft completely on their own: they started in a random world, crafted tools, traveled through the Nether and, after 27 hours and 14 minutes, defeated the Ender Dragon. No human helped them. Here you’ll find out how the AI played, why it died 605 times, what the catch is and what parents should know.

In short: Researchers Maxence Faldor, Satinder Singh and Roberta Raileanu from Google DeepMind published the experiment on the research platform arXiv on October 15, 2026. Four agents running the language model Gemini 4 Argon each controlled one player character, not with mouse and keyboard, but with programs they wrote themselves. They split up the tasks on their own, messaged each other in the chat and learned from their mistakes. According to the researchers, this is the first time AI agents have beaten Minecraft completely without help and without custom-built Minecraft tools. The catch: they played on Easy, and the AI knew more about its surroundings than a human player would.

The experiment at a glance

As of October 27, 2026. All figures come from the study and from reports by The Decoder (October 18, 2026) and The Next Web (October 19, 2026).

How does an AI play Minecraft?

The agents never saw the game. They didn’t get an image and didn’t press a single key. Instead, they wrote short programs in the JavaScript programming language, for example: “Walk to these coordinates and mine every iron ore within 16 blocks.” Mineflayer is a free code library that lets programs control Minecraft characters. It carried this out in the game and reported back as text where the character was standing, how many hearts it had left, what was in its inventory or which error had occurred. Then the agent wrote the next program.

Mineflayer can make the character walk, dig, place blocks, craft items and attack. But Mineflayer doesn’t know how to play Minecraft. The agents had to figure out for themselves what to do and in which order. The researchers stress that they gave them no game guide, no ready-made route and no Minecraft tools, just a short goal: defeat the Ender Dragon.

The game ran on version 1.20.4 of the Java Edition. That’s a bit older; the current Java version is 26.3. For the experiment, this hardly matters: the path to the dragon has been the same for years.

From the first tree to the Ender Dragon

The four agents were called janesick, gyldenia, auratian and bulicame. After just ten minutes, janesick suggested in the chat how to split up the work, and less than a minute later auratian replied with a different plan. Here’s how it went from there:

1. The first two hours: The team found a village, made iron tools, found diamonds and built a Nether portal. It was lit after 1 hour and 42 minutes.
2. Hours 2 to 11, in the Nether: janesick found a Nether fortress with blazes. The others hunted Endermen for Ender pearls, and they did it cleverly: they built bunkers only two blocks high. Endermen are almost three blocks tall and can’t fit inside. The trip back with the blaze rod took more than six hours, partly because a Ghast fireball destroyed items they had collected.
3. Hours 10 to 13, finding the stronghold: janesick threw two Eyes of Ender, measured their flight paths and calculated where the lines cross. The estimate was only 43 meters off from the portal room, which was 1.3 kilometers away.
4. Hours 13 to 27, the dragon fight: The battle in the End lasted almost 14 hours. The breakthrough only came after about 21 hours: auratian noticed that the ten End crystals on the obsidian pillars kept healing the dragon. The solution was surprisingly simple: stack dirt, climb up the pillar, smash the crystal by hand and dig back down. 39 minutes after the last crystal, the dragon was defeated. bulicame landed the final hit with only 2.5 of 20 health points left.

Almost every Minecraft fan knows that End crystals heal the dragon. For the AI team, though, it only became the turning point after many hours and dozens of deaths. Knowing something isn’t enough; you also have to use it at the right moment.

Learning from mistakes: 605 deaths

The number sounds embarrassing at first, but it’s actually the most interesting part. The agents were mostly killed by mobs, and about 22 percent of the programs ended with an error. What matters is what happened next: the agents turned setbacks into rules for the whole team. After the Ghast attack, auratian set up a rule for a safe route through the Nether, and two minutes later janesick followed up with the cause and a fix. In the End, they noted that you shouldn’t hang around on the arrival platform, because the dragon will knock you into the void there after about a minute.

When the dragon once got “stuck” and stopped moving properly, all four jumped into the void on purpose. That put them back in their beds in the Overworld, the empty End was unloaded, and the dragon reset. Human players use this trick too.

The catch: what the AI could do that humans can’t

The researchers list the limits of their experiment themselves, and they’re important before anyone starts talking about a “super AI”:

• X-ray vision: Mineflayer tells the agents exactly which blocks and creatures are around them, even behind solid stone. They could even read the dragon’s internal state. A human has to see and interpret all of this, or can’t know it at all. An add-on also plans walking routes around obstacles.
• Easy mode: On Easy, mobs deal less damage and you can’t starve to death.
• Prior knowledge: Gemini 4 Argon already knows Minecraft and Mineflayer from its training data. So the test wasn’t whether an AI can learn an unknown game, but whether it can turn its knowledge into working programs and teamwork over an entire day.
• Only one attempt: This was the first run the researchers started. Whether it would work again next time is an open question.

For comparison, the researchers point out themselves that, according to the site HowLongToBeat, humans need about 45 hours on average for the main story, and the random-seed speedrun record is under seven minutes. So the AI was neither faster nor better than a good player. What’s new is that a team of general-purpose AI agents organized itself without help and stuck with one goal for a whole day.

DeepMind isn’t the only one, either: according to the study, two hobby projects had already beaten the dragon with AI before, but they used ready-made Minecraft tools or a fixed, easier world.

Why does Google do research with Minecraft?

Minecraft is ideal for AI research: the world is huge, every game is different, and reaching the Ender Dragon takes many steps that build on each other. That’s exactly what AI agents are supposed to manage in real life later on, for example when programming large software. The researchers write that teamwork, getting back up after mistakes and sticking with a task for more than a day are exactly the skills agents need to work reliably with people.

Google has used games for its AI before, for example StarCraft II with the AlphaStar system. If you’re curious about other AI trends around Minecraft: AI mashups that put Minecraft into GTA or Mario are popular right now too.

What parents should know

• This is research, not a toy. The agents ran on Google’s cloud computers in a sealed-off world. The researchers estimate the computing time up to the win alone at about $520 at the model’s launch price ($1,040 at the regular price), and about $810 for the whole session. There’s nothing your child could download and play with.
• Safety was built in. The agents’ programs could only control their own character; they couldn’t write files or use server commands. A fifth agent acted as an observer to make sure nobody cheated, and according to the study it found nothing. Researchers could have stopped the run at any time but didn’t need to step in.
• Bots are usually banned on servers. Mineflayer is freely available online. Anyone who uses it to farm or fight automatically on a public server is almost always breaking the rules and risks a ban. It belongs in the same category as aimbots and other kinds of cheating. If your child asks about “AI bots for Minecraft”, it’s worth having a conversation about it.
• A great conversation starter. The story nicely shows that even an expensive AI makes mistakes all the time and only gets better by trying things out. With older kids, you can talk about what AI can do, what it can’t, and why X-ray vision isn’t a fair comparison.
• Coding with Minecraft can be kid-friendly too. If your child finds the idea of controlling Minecraft with code exciting, there are learning options such as Minecraft Education. For an overview of the game itself, check out our guide for parents.

Frequently asked questions

Did an AI really beat Minecraft?

Yes. According to the study from October 15, 2026, four AI agents from Google DeepMind started in a random world and defeated the Ender Dragon after 27 hours and 14 minutes, without any human stepping in. However, they played on Easy, and not through the screen but through small programs.

How does an AI control a Minecraft character?

Without a screen or keyboard. The agents wrote short JavaScript programs that the Mineflayer library carried out in the game. What came back was position, health and inventory as text. In total, 2,783 programs were written.

Why did the AI die 605 times?

Because it had to try out a lot of things first. Most deaths were caused by mobs, 69 by the Ender Dragon. About 22 percent of the programs ended with an error. The agents turned their mistakes into rules for the team.

Can my child download this AI to play with?

No. It was a research experiment on Google’s computers, and according to the researchers, the computing time up to the win would have cost about $520. Minecraft bots do exist, but they are banned on most public servers.

Is AI now better at Minecraft than humans?

No. Humans need about 45 hours on average, and the random-seed speedrun record is under seven minutes. The AI played as a team of four, on Easy, and could even “see” through walls. What’s remarkable is that it organized itself and learned from its mistakes.
