However, current systems operate within constrained search spaces or require predefined research questions, limiting their capacity for true open-ended inquiry. Furthermore, while they generate hypotheses iteratively, they largely lack the ability to explicitly synthesize their own accumulated findings to uncover complex, interconnected phenomena. We introduce DiscoPER, an autonomous large language model-powered framework that conducts open-ended research by dynamically generating and executing code to explore datasets without pre-specified research objectives. To ensure rigorous scientific validity, every proposed discovery must pass statistical testing. To overcome the limitations of isolated search, our framework introduces a second-order reasoning mechanism that periodically analyzesits own accumulated discoveries. By treating prior discoveries as empirical data, DiscoPER identifies structural patterns, confounds, and epistemic gaps, actively redirecting hypothesis exploration toward uncharted regions of the search space.  \nThe search space is further expanded by incorporating tool use, enabling the system to explore hypotheses beyond structured metadata by seamlessly processing and extracting useful information from multimodal sources like images. Evaluated oniNatDisco, a new multimodal ecological knowledge benchmark with pattern-level ground truth obtained from peer-reviewed literature, DiscoPER recovers 8 of 9 known patterns with a 72.7% hypothesis support rate, outperforming both classical causal discovery and LLM-guided baselines. Ablations show that DiscoPER scales with more data, and confirms the benefits of second-order “meta-reflection”.  \n1 Introduction  \nScientific discovery is a cumulative process. Researchers build on prior findings, notice gaps in what has been tested, and revise theories based on accrued evidence. Most existing LLM-based discovery systems (e.g., [36, 18, 15]) treat each hypothesis generation step independently, i.e., the system is provided with a dataset or research question, it generates a hypothesis, and the loop resets. There is no mechanism for the system to survey what it has already learned and reason about what remains unknown. A human biologist, for instance, might notice that several pairwise correlations all involve the same variable and hypothesize a common cause, or review hundreds of field photographs to identify a seasonal migration pattern that no single observation reveals. This meta-level reflection across findings is central to science, yet is an aspect current discovery systems have largely ignored.  \nMoreover, existing systems are either restricted in what they can express or require external guidance to operate. Classical structure learning methods [39, 47, 8] search exhaustively over pairwise variable relationships but cannot express higher-order patterns such as interactions, mediation chains, or confound structures. Full-pipeline AI scientist systems [30, 15, 14] can generate rich hypotheses from literature and domain knowledge, but require initial research objectives or seed hypotheses to guide their search. Code-based concurrent works [18, 36] write executable analyses, but their search  \nPreprint.  \nFigure 1: We introduce DiscoPER, an iterative approach for autonomous scientific discovery that takes multimodal data as input and generates a set of validated discoveries pertaining to the input data as output. At each iteration, the system proposes hypotheses, executes statistical tests on the underlying data, and accepts only discoveries that pass held-out validation.
