# Quickstart

You're in a hurry. Pick the line that matches you.

## "I want to know which model is best at X"

1. [`stratix.layerlens.ai/models`](https://stratix.layerlens.ai/models) — browse the catalog
2. [Compare models](/5.-select-pick-the-model/compare-models.md) head-to-head
3. Read the relevant [Quarterly report](/5.-select-pick-the-model/quarterly-reports.md)

No signup. Five minutes.

## "I want to evaluate my AI on my data"

```bash
pip install layerlens --extra-index-url https://sdk.layerlens.ai/package
export LAYERLENS_STRATIX_API_KEY="..."
```

```python
from layerlens import Stratix
client = Stratix()
model = client.models.get_by_key("openai/gpt-4o")
benchmark = client.benchmarks.get_by_key("mmlu")
e = client.evaluations.create(model=model, benchmark=benchmark)
print(client.evaluations.wait_for_completion(e).accuracy)
```

[Sign up](/2.-get-started/sign-up.md) → [First evaluation](/2.-get-started/first-evaluation.md).

## "I just want to verify my key works (curl, language-agnostic)"

```bash
curl -H "X-API-Key: $LAYERLENS_STRATIX_API_KEY" \
 "https://stratix.layerlens.ai/api/v1/models?limit=3"
```

JSON back → you're good. 401 → see [Authentication](https://github.com/LayerLens/gitbook-full/blob/main/13-reference/api/auth.md).

## "I want to gate AI changes in CI"

[Tutorial 3: CI/CD quality gates](/6.-build-wire-your-code/03-cicd-gates.md). 30 minutes from "no gate" to "regression blocks merge."

## "I want to score live production traces"

[Tutorial 4: Score live traces](/8.-evaluate-score-the-outputs/04-score-traces.md). Continuous evaluation on real traffic.

## "I'm evaluating Stratix for my company"
