Code World Model: Building World Models for Computation – Jacob Kahn, FAIR Meta

Summary

Jacob Khan discusses the Code World Model (CWM), a research project aimed at building AI models that can reason, plan, and make decisions by predicting program execution more deeply than traditional token-based approaches. The research focuses on modeling code not just as syntax, but as a structured representation of program states and execution transitions, with the goal of creating more sophisticated computational understanding. By explicitly tracing program execution and developing neural models that can ingest and predict program state changes, the team hopes to advance code analysis, generation, and broader computational reasoning capabilities. The ultimate vision is to bridge the gap between world models and language models by creating more nuanced, execution-aware representations of computational processes.
