# Introduction

> What levers9 is, what it can do, and where to start

levers9 is the platform behind [Levers AI Lab](https://uselevers.com). It runs your Python on a cluster you
control: plain jobs, HTTP endpoints, background queues, crons, long-running boxes, sandboxes
for untrusted code, JupyterLab notebooks and GPU jobs, all from a decorator and one CLI.

On top of the runtime sit two labs. The **Data Lab** turns recordings and conversations into datasets that people
annotate, share under NDA and round-trip through spreadsheets. The **RL Arena** is where a call-centre team
listens to real calls, teaches the agent which reply is better, and ships a new version only when it beats the
old one on the same customers.

## Three layers

> **[Runtime](https://levers9.mintlify.site/sdk/parameters.md)**
>
> Jobs, endpoints, queues, crons, boxes, sandboxes, blueprints, volumes, secrets and GPUs. One decorator, the same knobs everywhere.

> **[Dashboard](https://levers9.mintlify.site/guides/dashboard.md)**
>
> Apps, containers, workers, storage, secrets, notebooks and model endpoints, live. Workspaces with environments and invited members.

> **[Labs](https://levers9.mintlify.site/lab/datasets.md)**
>
> Datasets with import, pre-labelling and annotation; the RL Arena with call logs, scenarios, side-by-side review, training and evaluation.

## Start here

> **[Quickstart](https://levers9.mintlify.site/quickstart.md)**
>
> Install the CLI, sign in, run your first job, use a GPU.

> **[Every feature](https://levers9.mintlify.site/features.md)**
>
> The full map of what the platform does, with a link to the page for each.

> **[Concepts](https://levers9.mintlify.site/concepts.md)**
>
> Jobs, blueprints, volumes, deployments, versions, workspaces, environments.

> **[Demos](https://levers9.mintlify.site/demos/cpu_job.md)**
>
> One small app per feature, with the exact commands, up to a four-stage L40S pipeline.

> **[CLI reference](https://levers9.mintlify.site/guides/cli.md)**
>
> Every command, grouped by what you are doing.

> **[RL Arena](https://levers9.mintlify.site/guides/rl-arena.md)**
>
> Listen, teach, ship: the human loop.
