Evaluation evidence

Try W&B Weave alongside Telemetry

Choose one W&B Weave workflow and test both systems with the same fixed dataset. Check which capabilities you still need before changing production monitoring.

  1. 1

    Inventory W&B Weave

    W&B Weave traces, ops, calls, and production monitoring

  2. 2

    Map one workflow

    Compact run, model, tool, evaluation, and terminal-outcome events with a safe correlation identifier; no trace-tree equivalent.

  3. 3

    Dual-run the fixture

    Exercise one successful run, tool retry, terminal failure, and feedback event while comparing privacy boundaries and correlation.

  4. 4

    Record the decision

    List required traces, prompt or model versions, datasets, scorers, feedback, guardrails, and production-monitoring workflows.

How Telemetry is different

  • Weave follows detailed LLM and agent executions as traces and versioned AI objects; Telemetry stores selected outcomes in named event tables.
  • Weave includes evaluation datasets, scorers, comparisons, feedback, and AI-specific monitoring that have no built-in Telemetry equivalent.
  • Telemetry applies the same SQL model to agent outcomes, product actions, billing, APIs, jobs, webhooks, and releases.

When Telemetry is a good fit

  • The primary question is aggregate AI reliability, cost, adoption, or accepted outcomes rather than trace-level debugging.
  • Keep detailed evaluation records in a specialist system. Send selected outcomes and their version identifiers to Telemetry.
  • The team wants explicit SQL and a shared event model across AI and non-AI product workflows.

Where each product is strongest

W&B Weave

  • End-to-end LLM and agent tracing with inputs, outputs, model usage, latency, cost, tool steps, and trace-level inspection.
  • Datasets, evaluation pipelines, custom and built-in scorers, version tracking, feedback, and result comparison.
  • A stronger fit when the team needs a connected AI development, evaluation, and production-monitoring workflow.

Telemetry

  • Compact run, request, tool, evaluation, and product-outcome events queried directly with DataFusion SQL.
  • Join AI results with accounts, releases, billing, reliability, and return visits.
  • Your application chooses which fields to send. You can exclude prompts, outputs, retrieved content, and detailed traces.

Evaluation checklist

Test the decision with a real workflow

  1. 1List required traces, prompt or model versions, datasets, scorers, feedback, guardrails, and production-monitoring workflows.
  2. 2Run one production investigation and one frozen evaluation with the same success definition, privacy boundary, and release identifiers.
  3. 3Verify current hosted or self-managed deployment, access, retention, export, evaluation volume, and pricing before deciding.

Migration path

Plan the query and event migration before changing tools

List the queries, alerts, exports, and retention you use today. Define the event fields they need and translate one query. Run both systems with the same test data. Check null handling, timestamps, and aggregates before moving more queries.
