- Greptile developed TREX, an AI-powered code reviewer that executes code to identify runtime bugs beyond static analysis.
- TREX evolved from standalone test generation to integrated subagents orchestrated by Greptile's reviewer, sharing context to avoid wasted compute.
- Multi-modal artifacts (screenshots, videos, logs) are generated to verify findings, enhancing trust and enabling downstream agent verification.
- A model-agnostic evaluation harness allows hot-swapping between frontier AI models, prioritizing recall and precision over latency.
- Sandboxed environments provide isolated, fast execution with reusable snapshots, ensuring trustworthy artifact generation.
- The vision expands beyond code review to an automated validation suite aimed at eliminating bugs on every PR.
