Braintrust Evals & CI/CD From stochastic prompts to deterministic verification.

Replacing manual prompt vibe checks with continuous evaluation pipelines. We engineer deterministic scoring rubrics, regression datasets, and live trace observability in Braintrust so enterprise agents never degrade in production.

The benefits of Braintrust Evals

Why enterprise engineering leaders standardize continuous agent evaluation and CI/CD gates on Braintrust.

Automated CI/CD regression gates before deploy

Every prompt edit, model swap, or tool schema change runs automatically against golden production datasets in Braintrust, blocking regressions before code reaches users.

Logs as Proprietary Asset

Real-world edge cases and production anomalies captured via live telemetry are converted in one click into permanent regression test cases.

Code-level scorers over subjective LLM judges

Combining deterministic Python assertion scorers with calibrated rubric evaluators to measure accuracy, latency, and token cost across every workflow step.

Architecture framework

The three essential layers connecting Braintrust evaluation pipelines to deterministic agent execution.

Evaluation & CI/CD Braintrust

Braintrust Evaluation Engine

Golden evaluation datasets, automated CI/CD pull-request scoring, and real-time latency and cost telemetry across models.

State & Ontology LangGraph

LangGraph State Core

Finite state machines and dynamic business ontologies that expose every node transition for granular step-by-step evaluation.

Verification Observability & Evals

Guardrails & Audit Suites

Deterministic schema validation, SQL query guardrails, human-in-the-loop checkpoints, and continuous regression testing.

From POC to production

Our practical approach to ensuring agent initiatives advance beyond prototypes into mission-critical systems:

Step 01 Validation

Technical, architectural, and business feasibility assessment before writing code.

Step 02 Golden Dataset & Scorer Design

Curating real enterprise edge cases into versioned Braintrust datasets and deterministic code-level scoring functions.

Step 03 CI/CD Pipeline Integration

Wiring Braintrust evaluation gates directly into GitHub Actions and LangGraph deployments to block hallucination regressions.

Step 04 Handover

Architecture documentation, evaluation test suites, and continuous knowledge transfer to your team.
