Agent observability, evaluation, and continuous improvement for production AI
Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
The multimodal data layer for computer vision and physical AI teams
Native video, image, LiDAR, audio, text, and sensor-fusion labeling in one workflow, with label lineage and quality controls built for production scale.
Use embedding-based search and model-in-the-loop curation to surface rare edge cases and close distribution gaps before they hurt model performance.
Orchestrate RLHF, rubric-based evaluation, and pairwise comparison for models in production, then route failures back into training.
Access vetted domain experts for annotation and training-ready data collection, fully integrated with the Encord platform.
