Strengths
- Integrates evaluation into application development with minimal code changes.
- Supports both ground truth and reference-free (LLM-as-judge) evaluation methods.
- OpenTelemetry traces enable compatibility with existing observability tools.
- Includes out-of-the-box feedback functions for common quality metrics.
- Community-driven with extensibility for custom feedback functions.
Limitations
- Requires additional provider packages for specific LLM integrations.
- Depends on external API keys and credentials for LLM providers.
- Ground truth evaluations require prepared datasets for initial experiments.
