AI Evaluator CLI — Node.js

Evaluate your LLM agents from the terminal. No browser. No dashboard.

npm install -g aievaluator

🧭 Tutorial — From Zero to CI/CD

Every step builds on the previous one. Start wherever makes sense for you.

Level 0 — Try it without installing anything

curl -s -X POST https://api.aievaluator.dev/api/v1/playground/evaluate \
  -H "Content-Type: application/json" \
  -d '{"queries":["What is 2+2?"],"metrics":["faithfulness"]}' | jq .

5 free per day. No key. No install.

Level 1 — Install and evaluate a single prompt

npm install -g aievaluator

aievaluator quick "What is the capital of France?" --expected "Paris"

You'll see a table with the score.

Level 2 — Sign up and scaffold a project

aievaluator login          # Get your key at https://aievaluator.dev/settings
aievaluator whoami         # Check your account

aievaluator init           # Creates evals/smoke-test.json + config + .gitignore

Edit evals/smoke-test.json with your own queries, then:

aievaluator quick --dataset ./evals/smoke-test.json

Level 3 — Evaluate your own agent

aievaluator eval \
  --agent https://chatbot-staging.acme.com/api/chat \
  --dataset ./evals/smoke-test.json \
  --metrics faithfulness,g_eval

Level 4 — Quality gates with per-metric thresholds

Set different bars for different metrics:

# faithfulness ≥ 90%, g_eval ≥ 75%
aievaluator eval --agent $URL --dataset ./tests.json \
  --thresholds faithfulness:0.90,g_eval:0.75

Or one bar for everything:

aievaluator eval --agent $URL --dataset ./tests.json --min-score 0.80

Works on quick too:

aievaluator quick "test" --min-score 0.80
aievaluator quick "test" --metrics faithfulness:0.90,g_eval:0.75

Level 5 — Custom evaluators inline

aievaluator eval --agent $URL --dataset ./tests.json \
  --metrics politeness,g_eval \
  --custom '{"name":"politeness","prompt":"Is the response polite and professional?","threshold":0.85}'

Combine with per-metric thresholds:

aievaluator eval --agent $URL --dataset ./tests.json \
  --metrics politeness,g_eval \
  --custom '{"name":"politeness","prompt":"Is the tone friendly?","threshold":0.7}' \
  --thresholds politeness:0.90,g_eval:0.80

Level 6 — CI/CD pipeline

aievaluator eval \
  --agent $STAGING_AGENT \
  --dataset ./evals/regression.json \
  --thresholds faithfulness:0.90,g_eval:0.75 \
  --min-score 0.80 \
  --ci \
  --format junit > report.xml

Env vars for CI:

export AIEVALUATOR_API_KEY="sk-..."
export AIEVALUATOR_ENGINE_URL="https://api.aievaluator.dev"

📊 Output Formats

• Table (default) — human-readable with scores and pass/fail icons
• JSON (--format json) — clean JSON on stdout, logs on stderr
• JUnit (--format junit) — native CI integration, <testcase> per query

Requirements

• Node.js 18+
