# 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"

* [What is LayerLens Stratix?](/1.-introduction/what-is-layerlens-stratix.md)
* [How Stratix compares](/1.-introduction/how-stratix-compares-deep.md)
* [Pricing](https://github.com/LayerLens/gitbook-full/blob/main/assets/screenshots/README.md)
* [Industry patterns](/4.2-industry-use-cases/travel-hospitality.md)

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.layerlens.ai/quickstart.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
