Tracing, eval pipelines and drift detection for LLM and agentic systems in production - sessions, turns, steps, tool calls and subagents, with cost and quality attached to each.
dfzoo AI Institute implements LLM observability for production systems. We install tracing over the entities an agentic system actually has - sessions, turns, steps, tool calls and subagents, not isolated model calls - build eval pipelines that score new prompt and model versions against your test sets, set up drift detection, and integrate the signals with your existing observability stack. The test set built during an evaluation stays with you as a CI gate and a production monitor, and we maintain and extend it after every model or prompt change. OpenTelemetry-based where possible; we work with Datadog, Honeycomb, Grafana, Langfuse, Arize, Helicone, Braintrust, LangSmith, W&B Weave, Confident AI and Galileo, we help you pick, and at high volume we show where self-hosting beats SaaS.
Map current LLM and agent calls across your codebase. Inventory features, prompts, providers, existing test sets and observability tooling.
Wrap sessions, turns, steps, tool calls and subagents with tracing. Forward to the chosen backend and validate every run surfaces end to end.
Build test sets per feature from real traffic and from prior evaluation findings. Wire eval runs into CI as a merge gate and mirror the same thresholds as a production monitor.
Walk the on-call team through dashboards, runbooks and incident scenarios. Hand over the test set as your asset, in your repository.
We extend the test set and rerun the regression after every model or prompt change, and report what moved and why.
Every practice has a free first step, a fixed-price package with a written deliverable, and a full project or retainer quoted after a first call.
A 60-minute intro call with an engineer, or the online self-assessment. You leave with a clear next step, no obligation.
Instrumentation of one LLM application: request-level tracing (prompt, response, latency, cost, version), one golden set of up to 100 cases, one quality and cost dashboard, an on-call runbook.
Not included: Observability platform licence costs, continuous evaluation retainer, instrumentation of further applications, on-call duty on our side.
