- Faros.ai data indicates LLMs modestly boost individual developer productivity but not at 10x levels.
- System-level metrics show deployment frequency decreased by 11%, and lead times increased nearly 5x.
- Quality metrics degraded sharply, with defect rates up by 50% per developer on average.
- System throughput is estimated to be down by 71-80% for teams using LLMs.
- Even high-performing engineering organizations experience similar negative downstream effects from LLM use.
- The author argues that LLMs' inherent unreliability makes them an unstable foundation for organizational value.
- A recommended approach is to avoid using LLMs for first drafts, instead leveraging them for editing and feedback.
