ARC‑AGI‑3 Developer Preview Agent Competition

Your objective: Build an agent that completes the most levels possible on three public ARC-AGI-3 games and two hidden games. Open for 3 weeks.

Spirit of the Developer Preview Competition

This is an informal, community‑driven preview competition designed to probe ARC‑AGI‑3’s new interactive games. ARC Prize retains full discretion over rules and awards, all of which may evolve.

• Stress‑test five new ARC‑AGI‑3 games
• Collect community feedback on agent tooling, API, & evaluation criteria
• Showcase techniques for building general‑purpose interactive agents
• Open source sharing: All submissions must be open source to be considered for prizes.

The ARC-AGI-3 Preview Competition is in partnership with HuggingFace.

Get Started

Head over to the ARC-AGI-3 API documentation or view the ARC-AGI-3 Agent tutorial video to view the steps below

1. Clone the ARC-AGI-3-Agents repo
2. View: the ARC-AGI-3 API documentation
3. Build: Create your own agent and run it on the three public games to view your progress
4. Submit: When you’re happy with a run, submit your solution. Hosts will select top submissions to run against the private games for scoring. If not selected, you'll be able to run your submission against the private games (once made public after the submission period) on your own.

Competition Scoring

During the submission window, 3 public games will be available to play and test on. After the submission window is closed, 3 private games will be made public.

To incentivize generalization (and not overfitting), public games score + ARC Prize discretion will be used determine which submissions will be tested on private games. Private game scores will determine the final ranking.

Notes:

• Tie‑breakers: If two agents have the same score, the one with the least number of actions across private games will be ranked higher. If a tie remains, the solution submitted first will be ranked higher.
• Documented and reproducible: Each submission must be easily reproduceable and documented. If we are not able to run your submission with minimal effort, we will not score it. For reference on how to run your submission, see the API documentation.
• ARC Prize Discretion For Agent Eligibility: Our goal is to not encourage solutions which are overfit to public games. Therefore, even if your agent is able to run on the public games, we may not select it for the private games if we believe it is overfit.
• Leaderboard: The leaderboard seen at three.arcprize.org will be used to determine the in-competition ranking.
