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.

Provides exceptionally fast inference speeds and robust fine-tuning tools, competing directly on open-source model deployment performance.
Offers similar low-cost serverless inference for open-weight models, but with a simpler pay-as-you-go pricing model.
Excels at experiment tracking and model registry workflows, but is less purpose-built for real-time LLM production observability.
