Opik to Telemetry: a reversible evaluation path
Map a bounded Opik workflow, preserve the capabilities that remain necessary, and compare both systems over the same closed fixture before changing production coverage.
- 1
Inventory Opik
Opik production traces and span inspection
- 2
Map one workflow
No direct trace equivalent; retain Opik for detailed execution evidence and send approved terminal outcomes with a safe run identifier.
- 3
Dual-run the fixture
Test one model and tool trace, recovered retry, terminal failure, and correlation handoff without duplicating sensitive content.
- 4
Record the decision
List required traces, datasets, metrics, experiments, test suites, online evaluation, and human-review workflows.
How Telemetry is different
- Opik provides AI-specific tracing, evaluation datasets, metrics, experiments, and test suites; Telemetry provides general event analytics.
- Opik supports detailed production trace review and evaluation loops; Telemetry emphasizes compact terminal outcomes.
- Telemetry joins AI quality and cost to product, account, billing, API, job, and release events using SQL.
When Telemetry is a good fit
- The team needs aggregate outcome, cost, adoption, and reliability analysis more than an evaluation workbench.
- Opik remains the trace and evaluation system while Telemetry stores reviewed product outcomes.
- A shared run identifier can connect systems without duplicating sensitive AI content.
Where each product is strongest
Opik
- Purpose-built LLM traces, datasets, prebuilt and custom evaluation metrics, experiments, and behavioral test suites.
- Open-source deployment options and AI-specific workflows for turning production failures into regression tests.
- A stronger fit when detailed AI evaluation and trace evidence are the primary requirement.
Telemetry
- A smaller application-owned schema for accepted, rejected, failed, escalated, or handed-off outcomes.
- SQL analysis across AI workflows and the rest of a SaaS product without adopting a trace-first model.
- Privacy boundaries that can exclude raw prompts, completions, retrieved documents, and tool payloads.
Evaluation checklist
Test the decision with a real workflow
- 1List required traces, datasets, metrics, experiments, test suites, online evaluation, and human-review workflows.
- 2Evaluate one real failure, one regression test, and one aggregate release comparison using the same approved fixture.
- 3Compare self-hosting work, access, retention, export, model-judge cost, and current hosted-service packaging.
Migration path
Plan the query and event migration before changing tools
Inventory the queries, alerts, exports, and retention requirements the current workflow actually uses. Map those requirements to a typed event contract, translate a representative query, and dual-run the same fixture before expanding coverage. Similar operators do not guarantee equivalent null handling, time semantics, or aggregation results.
Opik workflow
Opik production traces and span inspection
Telemetry mapping
No direct trace equivalent; retain Opik for detailed execution evidence and send approved terminal outcomes with a safe run identifier.
Dual-run validation
Test one model and tool trace, recovered retry, terminal failure, and correlation handoff without duplicating sensitive content.
Opik workflow
Opik datasets, evaluation metrics, experiments, and test suites
Telemetry mapping
Versioned evaluation result events for aggregate SQL; keep Opik for test execution, datasets, judge metrics, and failure review.
Dual-run validation
Compare a frozen baseline and candidate with identical examples, metric versions, thresholds, execution policy, and evaluated coverage.
Opik workflow
Opik aggregate production evaluation views
Telemetry mapping
SQL dashboards joining evaluated quality and cost to releases, accounts, product outcomes, incidents, and handoffs.
Dual-run validation
Reconcile trace count, evaluation coverage, score distribution, latency, cost, and downstream acceptance over a fixed window.
Try the wedge
Start with one backend workflow
Pick an API route, AI workflow, webhook, or job queue. Send structured events and query them before expanding coverage.
