Getting started

Getting started with LayerLens Stratix — go from zero to your first evaluation, or pick the entry point that fits your role.

Welcome. This section gets you from "I just heard of LayerLens Stratix" to "I have a real evaluation running against my data" — fast. The page you're on is a launchpad; the links below are the actual ride.

Hit an error already? Skip ahead to Common first-day errors — install, auth, env-var, and network problems most people see in their first hour, with fixes.

Fastest path: 5 minutes to a real score

If you have a Python environment and 5 minutes, do this first. One file, copy-paste-runnable, ends with a real accuracy number and a UI link.

Run your first evaluation in 5 minutes

One Python script. Install, auth, fetch a model, fetch a benchmark, run, inspect results.

Start

Did the 5-minute run. Now what?

Top 5 starter recipes

The five highest-ROI cookbook recipes for week one — one per workflow stage.

Match your role and goal to the right entry point: Public, Premium, or SDK.

Prefer to start in the UI?

Not everyone wants to start in Python. Three browser-first entry points — pick whichever matches what you're trying to learn.

Stratix Public

Browse models, compare them, read benchmark scores. No account needed.

Browse

Stratix Premium

Sign up, run your first private evaluation, build a judge in the UI.

Sign up

Python SDK

pip install layerlens --extra-index-url https://sdk.layerlens.ai/package and run an eval from code.

Install

Most teams use all three together. A typical first day: Public to shortlist candidate models, Premium to run a private eval on your data, SDK to wire the winner into CI.

Browse by depth

Once you've run your first eval, dig into whichever shape of content matches how you learn.

Format	When to use it	Index
Tutorials	Guided, end-to-end, sequenced. Take an evening, finish a working pipeline.	All tutorials
Cookbook	Problem-shaped recipes. "I have task X, give me code."	All cookbook recipes
Guides	Task-oriented walkthroughs. Bigger than a recipe, smaller than a tutorial.	All guides

The workflow under the hood

Everything in Stratix maps to five stages. Knowing the stage helps you find the right doc fast.

Stage	What you're doing	Where it lives
Select	Pick models, benchmarks, datasets to evaluate against	§5 Select
Build	Instrument your code so Stratix can see what it does	§6 Build
Observe	Capture traces, route them to where they're scored	§7 Observe
Evaluate	Score runs with judges and code graders	§8 Evaluate
Improve	Optimize judges, cut cost, regression-protect	§9 Improve

See The Stratix workflow for the full picture.

When something breaks

• Common first-day errors — auth, install, network, env-var problems.
• SDK troubleshooting — deeper SDK-specific issues.
• Support — how to reach a human.
• Status and reliability — is it us or you?

Where to next

The honest answer depends on what you're trying to do. If you're not sure:

1. Run Your first evaluation in 5 minutes.
2. Pick one of the Top 5 starter recipes that matches a real problem you have.
3. When you hit something specific you need to learn, return to All tutorials / All cookbook recipes / All guides.
