# Personas and paths

Five personas, five paths — Builder, Operator, Researcher, Admin, Buyer.

Stratix is read by five kinds of people. Each one has a different first question and a different "ah-ha" moment. Pick your path; we'll get you there fast.

## Builder

> *"I'm shipping an AI feature and I want it to be good."*

You write code. Your name is on the PR that adds the new prompt or the new agent. You want a tight feedback loop: write a change, run an eval, see the score change.

**First questions:** "How do I write my first eval? How do I score outputs my eyes can't grade?"

**Path:**

1. [Sign up for Premium](/2.-get-started/sign-up.md)
2. [Tutorial 1: First evaluation in 10 minutes](/8.-evaluate-score-the-outputs/01-first-evaluation.md)
3. [Tutorial 2: Build your first judge](/8.-evaluate-score-the-outputs/02-first-judge.md)
4. [Workflow: Instrument](/9.-improve-tune-the-system/workflow.md) → [Evaluate](/9.-improve-tune-the-system/workflow.md)
5. [SDK quickstart](/2.-get-started/sdk.md)
6. [Cookbook](/2.-get-started/all-cookbook-recipes.md) — recipes by problem, framework, and integration

**You'll know you're winning when:** every prompt change has an eval result attached and you've stopped trusting your gut.

## Operator

> *"I run live AI in production and I need to keep it healthy."*

You own the on-call. You watch dashboards. You ship rollback scripts. AI quality is your latest reliability surface.

**First questions:** "How do I score real production traffic? How do I get paged when quality drifts?"

**Path:**

1. [Concept: Continuous evaluation](/7.-observe-see-whats-happening/continuous-evaluation.md)
2. [Concept: Traces and spans](/6.-build-wire-your-code/traces-and-spans.md)
3. [Tutorial 4: Score live traces](/8.-evaluate-score-the-outputs/04-score-traces.md)
4. [Workflow: Observe](/9.-improve-tune-the-system/workflow.md) → [Govern](/9.-improve-tune-the-system/workflow.md)
5. [Use case: AI quality gates in CI/CD](/4.1-general-use-cases/ai-quality-gates-cicd.md)
6. [Status and reliability](https://github.com/LayerLens/gitbook-full/blob/main/13-reference/status/README.md)

**You'll know you're winning when:** quality regressions surface to you before they surface to customers.

## Researcher

> *"I want to know which model is best for my use case."*

You don't (yet) need to wire anything up. You need ground truth — what's the frontier, what's commoditized, what's punching above its weight.

**First questions:** "Which model is best at structured-output tasks? How is open-weight catching up?"

**Path:**

1. [Stratix Public](/1.-introduction/01-introduction.md) — start here, no signup
2. [Models catalog](/5.-select-pick-the-model/models-catalog.md)
3. [Benchmarks catalog](/5.-select-pick-the-model/benchmarks-catalog.md)
4. [Compare models](/5.-select-pick-the-model/compare-models.md) — head-to-head
5. [Quarterly reports](/5.-select-pick-the-model/quarterly-reports.md)
6. [Public evaluations](/5.-select-pick-the-model/public-evaluations.md)
7. (Optional) [Sign up for Premium](/2.-get-started/sign-up.md) to run a private evaluation on your own data

**You'll know you're winning when:** you can answer "is X actually better than Y for our task" in under 5 minutes.

## Admin

> *"I'm setting up Stratix for my team."*

You provision seats, manage SSO, watch the bill, write the IT-approval memo.

**First questions:** "How does auth work? How do I manage multiple orgs and seats? What's the data residency story?"

**Path:**

1. [Sign up](/2.-get-started/sign-up.md)
2. [Organizations and multi-org](https://github.com/LayerLens/gitbook-full/blob/main/13-reference/sdk-python/organizations.md)
3. [Team management](/11.-admin/team-management.md)
4. [ECU credits and billing](/11.-admin/ecu-credits-billing.md)
5. [Settings](/11.-admin/settings.md)
6. [Enterprise](/1.-introduction/01-introduction.md) — SSO, data residency,
7. [Security and compliance](/1.-introduction/01-introduction.md)

**You'll know you're winning when:** auth, billing, and access control are boring.

## Buyer

> *"I'm evaluating Stratix for purchase."*

You may not be the user. You're the budget owner, the AI-platform PM, the head of engineering. You need to know whether Stratix is the right bet — and whether your team will adopt it.

**First questions:** "How does Stratix compare to Braintrust/LangSmith/etc? What's the ROI? Who else uses it?"

**Path:**

1. [What is LayerLens Stratix?](/1.-introduction/what-is-layerlens-stratix.md)
2. [Three experiences](/1.-introduction/three-experiences.md)
3. [How Stratix compares](/1.-introduction/how-stratix-compares-deep.md)
4. [Pricing](/1.-introduction/01-introduction.md)
5. [Industry patterns](/4.2-industry-use-cases/travel-hospitality.md)
6. [Use cases](/4.1-general-use-cases/general.md)
7. [Enterprise](/1.-introduction/01-introduction.md)
8. [Security and compliance](/1.-introduction/01-introduction.md)

**You'll know you're winning when:** you have a one-page rationale and your team has run a real evaluation in the trial.
