摘要

本报告记录了针对代码生成与代码推理模型Code World Model（CWM）的预备性评估。该模型由Meta公司开发，我们根据前沿人工智能框架中界定的可能引发灾难性风险的领域进行了预发布测试，并评估了模型的错位倾向。评估结果表明，CWM并未在当前AI生态系统既有风险之外产生额外的前沿风险。因此，我们决定以开放权重模型的形式发布该模型。

This report documents the preparedness assessment of Code World Model (CWM), a model for code generation and reasoning about code from Meta. We conducted pre-release testing across domains identified in our Frontier AI Framework as potentially presenting catastrophic risks, and also evaluated the model's misaligned propensities. Our assessment found that CWM does not pose additional frontier risks beyond those present in the current AI ecosystem. We therefore release it as an open-weight model.
