ExplorationBench: Measuring AI Systems' Exploration in Verifiable Alien Worlds
TLDR
Introduces ExplorationBench, a benchmark with verifiable alien-world sandboxes to evaluate AI systems' scientific exploration, including hypothesis framing and experiment design, avoiding recall-based solutions.
Reasoning
The paper proposes a novel, concrete benchmark that addresses the difficult evaluation of scientific exploration by using executable alien worlds with exact verification. It evaluates multiple AI systems and reveals performance variability, but the synthetic alien-world setting may limit direct transferability to real-world scientific discovery, and details on task construction and limitations are sparse in the abstract.

Innovations
- Introduces ExplorationBench, a benchmark that makes evaluation of scientific exploration tractable through verifiable Alien Worlds with executable rules and knowledge-conflicting tasks, enabling exact answer checking and preventing solutions by recall.
- Provides two sandboxes, AlienCode and AlienLogic, containing 31 and 24 discovery targets and 70 tasks each, with a flawed manual, task-specific environmental feedback, and a dedicated tool-call schema.
- Defines an evaluation protocol where AI systems must explore a sandbox and then solve held-out tasks, focusing on acquiring and applying genuinely new, unfamiliar rules.
Methodology
The benchmark comprises two sandboxes, AlienCode and AlienLogic, each with discovery targets, tasks, a flawed manual, task-specific environmental feedback, and a dedicated tool-call schema. Systems use these resources to explore the sandbox and then solve held-out tasks. Ten AI systems are evaluated, with exact answer checking enabled by executable world rules and recall-based shortcuts blocked by conflicts with familiar knowledge.
Key Results
The strongest evaluated AI systems can acquire and apply unfamiliar rules, but performance varies substantially across trajectories, and continued exploration can stall or reverse earlier gains.
Limitations
- The work is described only as a step toward AI systems that can acquire and apply genuinely new knowledge through exploration, rather than a complete solution to scientific exploration.
- System behavior is unstable: performance varies substantially across trajectories and continued exploration can stall or reverse earlier gains.
