hwchase17 · x · 2026-08-19
LangChain released LangSmith Tuned Evaluators to help teams sift through massive agent trace data.
Key Features:
- Automated Scoring: Evaluates agent behavior in production, starting with "Perceived Error".
- Cost Efficiency: Uses fine-tuned small models to detect signals instead of expensive frontier models.
- Performance: In benchmarks, the specialized model outperformed tested frontier models and reduced evaluation costs by 82%.
This approach envisions a future of hundreds of small, cheap evaluations running constantly to improve agents.
