Stacks / 7 workflow stages

Evaluate and Harden an AI System

Turn subjective model quality into repeatable tests, traces, adversarial checks, and a release gate.

Best for

Teams moving an AI feature from 'it seems to work' toward measurable reliability and safer production behavior.

Outcome

A practical evaluation loop covering task quality, regressions, tracing, retrieval quality where relevant, and adversarial/security testing.

Not for

Early ideation where the product task itself is still undefined and there is nothing stable enough to evaluate.

Use this as a decision framework, not a mandatory shopping list. Swap or skip layers based on your existing stack, constraints, and risk profile.

01

1. Define the eval set

OpenAI Evaluation Flywheel

Start by turning real product behavior and failures into a repeatable evaluation loop.

2. Run regression tests

Braintrust

Track task-level quality across prompts, models, and application changes instead of comparing outputs by feel.

03

3. Evaluate retrieval if applicable

Ragas

Measure whether retrieval systems actually return relevant evidence and grounded answers.

AlternativesDeepEval

04

4. Trace failures

Arize Phoenix

Inspect traces and model behavior so a failed evaluation can be diagnosed rather than merely counted.

05

5. Red-team the application

NVIDIA garak

Probe common LLM vulnerabilities and failure modes with a purpose-built red-team tool.

6. Threat-model systematically

MITRE ATLAS

Use a structured adversarial framework to reason about attacks beyond individual prompt-injection examples.

7. Make release criteria explicit

Anthropic Security Guidance

Pair quality metrics with concrete security and deployment considerations before exposing the system more broadly.
