Code World Model: How Meta’s AI Revolutionizes Code Understanding and Debugging

“ What if an AI could not only write code but also simulate in its mind how that code will alter the state of a system? This is the paradigm shift offered by Code World Model (CWM). As developers, when a new code-generation model emerges, we ask two key questions: 1) How good is it at writing code? 2) Does it truly understand what happens when the code runs? Most large language models (LLMs) excel at the first but struggle with the second, leading to code that looks correct but fails at runtime or can’t reason about multi-step software engineering …
