Release-aware evaluationCompare candidate behavior with the production baseline and required segments.
Quality-adjusted costMeasure spend against accepted outcomes, not only provider token totals.
THE EVALARA CONTROL LOOP

From production behavior to a defensible release decision.

AI systems regress across prompts, models, retrieval, tools, latency, and cost. Evalara keeps those changes in one evidence path.

TRACE OBSERVABILITY

Debug the execution, not just the final answer.

See the prompt, model, retrieval, tool calls, retries, scores, latency, and token path behind each outcome.

CHALLENGE THE CANDIDATE

Turn real failures into tests that protect the next release.

Curate production cases, compare candidate changes, calibrate scorers, and investigate row-level regressions without losing trace context.

  • Versioned datasets and representative segments
  • Code, model, rule, and human scoring
  • Critical failure gates and review queues

LEARN IN PRODUCTION

Optimize cost without trading away the outcome.

Connect provider charges and token use to releases, features, retries, latency, and successful tasks.

  • Cost per successful task
  • Model, feature, and segment attribution
  • Retry, cache, and routing anomaly detection

THE SYSTEM AROUND THE LOOP

Evidence can move. Control boundaries should not.

The release loop is fitted to the customer's production system, instrumentation surface, data boundary, and operating responsibilities.

A PILOT, NOT A GENERIC SIGNUP

Begin with one production workflow worth controlling.

We define the trace, evaluation standard, security boundary, pilot acceptance criteria, and production rollout before opening the dedicated workspace.

CONTROL BY DESIGN

Trace evidence is sensitive engineering data.

Access, payload handling, retention, environment separation, and deployment requirements are confirmed during implementation.

Review security and governance →
01Dedicated workspace

A named environment is provisioned for the customer and scoped to the agreed applications.

02Administrator-controlled access

Customer administrators invite users and define authorized project access.

03Permission-aware evidence

Raw payload access, exports, retention, and sensitive fields remain explicit controls.

04Auditable release history

Versions, evaluations, reviews, exceptions, and decisions remain reconstructable.

START WITH A REAL RELEASE DECISION

Put one production AI workflow under release control.

The technical assessment maps the execution path, quality standard, release decision, cost dimensions, security boundary, and practical pilot scope.
