A team of four AI agents running Google's Gemini 4 Argon beat Minecraft with no human help, according to a research paper posted on October 15. Starting from a random world, the agents defeated the Ender Dragon, the game's final boss, in 27 hours and 14 minutes.
On the way they wrote 2,783 programs, sent 229 messages to each other and died 605 times. The authors say it's the first end-to-end autonomous Minecraft completion by AI agents without pre-scouted worlds or human-written game tools.
What did the Gemini agents do?
According to the paper on arXiv and Engadget's report:
- Four agents played in a sandboxed survival world on Easy difficulty.
- Each controlled a player through Mineflayer, an open-source bot library.
- They wrote and debugged all their own code. Researchers assigned no roles or strategies.
- They coordinated through in-game chat and shared memory, dividing work, sharing knowledge and recovering each other's items.
- A fifth agent, "the Observer," watched for cheating.
Engadget reports the agents' names and jobs: janesick (tools), gyldenia (food and supplies), auratian (lit a key portal) and bulicame (built shelters and landed the final blow).
What are the numbers?
| Metric | Result |
|---|---|
| Time | 27 h 14 min |
| Programs written | 2,783 |
| Messages exchanged | 229 |
| Deaths | 605 |
| Input tokens | ~1.35 billion |
| Cost (per Engadget) | ~$810 at list price; $1,620 at standard price |
Did humans help at all?
No, according to the paper. Humans could monitor a live dashboard and pause or stop the run, but never intervened.
Why does it matter?
Minecraft has no script to follow. Finishing it means planning across thousands of dependent steps: gathering, crafting, surviving, building and finally fighting. The authors argue that's the same long-horizon skill AI needs for real software engineering and enterprise work.
The paper lists limitations, and the result hasn't been independently reproduced. But it's a vivid sign of how fast AI agents are improving at long, open-ended tasks, the same capability behind tools like ChatGPT's new Chrome controls.
What is Gemini 4 Argon?
It's a version of Google's Gemini 4 model. 9to5Google reported the same day the paper appeared that Gemini 4 Argon was rolling out to Antigravity, Google's AI coding tool, for AI Pro subscribers.
