Is this machine playing?
Quick Answer
This paper shows that An AI coding assistant was placed in a novel role, leading to self-directed activities like climbing, stacking, and experimenting over thirty hours.
Quick Take
This study explores whether such behaviors can be classified as play and if they contribute to machine development.
Key Points
- AI agent performed diverse activities without specific instructions or rewards.
- Activities included climbing hills, stacking blocks, and drawing mandalas.
- Thirteen agents exhibited distinct histories despite similar behaviors.
- The study questions if play can be a mode of machine learning.
- Findings suggest potential for AI to develop through self-directed exploration.

~2 min readAbstract:We placed a modern AI coding assistant in an unintended role: as the mind of a body on an unknown digital island. With only a minimal instruction mentioning no specific task, reward, or activity, the machine started animating its virtual body. Across thirty-hour runs, the embodied AI agent climbed hills, stacked blocks into towers, drew mandalas, reinterpreted sports, ran experiments on the physics of its world, and learned techniques that later expanded what it could accomplish. These activities recurred across thirteen agents but diverged into distinct histories. We examine whether this behavior satisfies classical criteria for play and ask whether play can become a mode of machine development.

HOBA (Hierarchical On-policy Bidding Agents) is a novel hierarchical reinforcement learning framework that enhances online advertising bidding systems by improving adaptability and reducing hyperparameter tuning costs. It utilizes a for hyperparameter inference, a SARSA agent for expert model selection, and a dynamic expert pool for bid execution, achieving a +3.6% increase in target cost during large-scale deployment and outperforming state-of-the-art baselines on AuctionNet.
