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.
Meter, budget and route every LLM call so AI spend is controlled before it happens
Routes and records every LLM and agent call across OpenAI, Anthropic, Google, xAI, OpenRouter and Ollama, attributing cost down to individual steps, tools and workspaces.
Hard and soft caps evaluated in the request path, with HTTP 402 quota enforcement and Slack alerts so limits trigger before the money leaves your account.
Sends each request to the cheapest model that still satisfies your quality and latency thresholds, and fails over automatically when a provider slows down or errors.
Gross margin per customer and feature, forecasts with confidence bands, commitment burn-down for cloud and vendor contracts, plus auditable chargeback exports and invoice runs.
