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.
AI-native enterprise skills management and learning platform
Get a real-time view of workforce capability, benchmark skills against role and technology needs, and see where to focus development next.
An ICF-aligned AI coach embedded in the platform turns development needs into concrete coaching goals and links them to relevant learning.
Practice realistic conversations and judgement scenarios in a safe AI environment before applying those skills on live work.
Combine self-paced courses, live instructor-led training, hands-on labs and coaching into paths that fit how teams actually work.
