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 & machine learning consulting that ships production systems
Design and build of production generative AI features — summarization, topic extraction, extraction and classification — on top of modern large language models.
Image recognition, object detection and document parsing pipelines that convert unstructured files and visual data into structured, usable records.
Conversational assistants wired into a company's own tools and data so they answer with business context instead of generic model output.
Backend automations and agentic systems that remove repetitive manual work for service companies and plug into existing software stacks.
Excels at experiment tracking and model registry workflows, but is less purpose-built for real-time LLM production observability.
