# Overview

Overview of LayerLens Stratix — three experiences, the workflow spine, what's in the platform.

LayerLens Stratix is the AI evaluation platform for teams who need to know — before customers do — whether a model, a prompt, or an agent is good enough to ship. Three customer-facing experiences cover the full evaluation lifecycle: **Stratix Public** for anonymous research, **Stratix Premium** for team workflows, and the **Python SDK** for programmatic access.

## The Stratix Workflow

Six stages from picking a model to governing it in production:

1. **Select** — review leaderboards and benchmarks; optionally compare candidates side-by-side.
2. **Build** — wire your code or agent to emit traces.
3. **Observe** — see real production behavior across surfaces.
4. **Evaluate** — score outputs with LLM judges, LLM-backed scorers, and code graders.
5. **Improve** — tune prompts and judges (GEPA); re-run.
6. **Govern** — enforce gates in CI/CD and across your org.

Every concept, how-to, tutorial, and recipe in these docs maps to one of these stages. [Learn the workflow →](/1.-introduction/the-stratix-workflow.md)
