CodeShield

CodeShield is a robust inference-time filtering tool developed by Meta to prevent the introduction of insecure code generated by Large Language Models (LLMs) into production systems. It acts as a guardrail to intercept and filter out potentially insecure code before it's integrated into a codebase. Currently at version 1.0.1, its release cadence is not explicitly defined but is part of Meta's broader Purple Llama project for AI safety and security.
