Integrating Over 20 Advanced Algorithms: Outperforming GPT-4o with Autonomous Causal Analysis Intelligent Agent}
Meta's new AI system, Causal-Copilot, combines 20+ algorithms for autonomous causal discovery and inference, surpassing GPT-4o, enabling precise decision-making in complex scenarios.
Researchers from UC San Diego's Biwei Huang Lab have developed Causal-Copilot, an autonomous causal analysis agent. The team, led by first authors Xinyue Wang, Kun Zhou, and Wenyi Wu, focuses on causal inference and machine learning, with strong support from startup Abel.ai.
A Common Dilemma
Imagine you're a biologist with gene expression data, suspecting regulatory relationships. Or a sociologist evaluating education policies. Despite rich theories and tools, causal analysis remains difficult to use due to high technical barriers.
Limitations of Pretrained Models
Current AI systems, including state-of-the-art large language models, are pattern recognizers. They can note correlations like “A and B often co-occur” but can't determine causality—whether A causes B or vice versa.
This leads to issues in real applications. For example, AI might suggest promoting an educational app because of correlation with better grades, but causal analysis could reveal that better students are more likely to use the app.
Causal analysis involves two core tasks: discovery (identifying causal relationships) and inference (quantifying effects of interventions). Mastering these requires deep statistical expertise, creating barriers for many researchers.
Causal-Copilot: Making Complexity Simple
Our solution: let AI handle the difficult parts—method selection and parameter tuning. Causal-Copilot integrates over 20 advanced causal algorithms, creating a comprehensive “one-stop” causal analysis system. It automatically finds suitable methods for data, whether tabular, time-series, linear, or nonlinear, noisy or clean.

Unified Causal Discovery and Inference System
Causal-Copilot automates the entire process of causal discovery and inference, covering structure learning to effect estimation, handling various data types and challenges like confounding, missing data, and heterogeneity.
Performance evaluation across diverse datasets, including online shop, climate, and abalone datasets, shows that Causal-Copilot outperforms GPT-4-based causal algorithms and traditional methods, especially in large-scale networks.
