Datadog developed an LLM-powered tool called BewAIre to review pull requests for malicious activity in real time. The system processes code changes and classifies them, achieving over 99.3% accuracy while minimizing false positives. It addresses the challenges posed by the increasing volume of PRs and the sophistication of attacks.

Sketch.dev experienced multiple outages caused by LLM-generated code that introduced a bug during a refactoring process, leading to infinite loops in error handling. Despite initial stability, the issues persisted until the offending code was reverted and clipboard support was added to improve code management. The incident highlights the need for better tooling to catch subtle errors during code reviews, especially when using LLMs for coding tasks.
