| description.long | A platform for building and evaluating AI systems that synthesizes test datasets from multiple sources, compresses expensive LLM evaluators into efficient models, and provides production monitoring with real-time observability. | A framework that lets developers create and run evaluations to measure LLM performance, providing both pre-built benchmarks and tools to write custom tests tailored to specific use cases without requiring proprietary evaluation infrastructure. |
