# Playground Page

> Launch services, chat, and run A/B comparisons from the web

The **Playground** page (`/playground`) is for short-lived model trials. Sessions have a TTL and are reclaimed automatically. Use [Model Deployments](/en/console/model-deployments) when you need a stable endpoint, tokens, recovery, or revisions.

## Starting a service

1. Choose a model: the **training artifacts** dropdown (runs with an hf\_export), or directly enter an HF id / shared-storage path;
2. Choose GPU count (= tensor parallelism) and TTL;
3. Launch. The status card updates in real time: starting → ready → remaining TTL.

## Chat

* Streaming output, adjustable system prompt / temperature / max tokens;
* Conversation history stays on the page (cleared on refresh, never stored).

## A/B comparison

Pick two ready services side by side: the same input is sent to both simultaneously and the outputs render in parallel — alignment differences between SFT vs GRPO, or v1 vs v2, become directly visible.

## Management

The page lists **all of my services**: endpoint address, GPUs occupied, remaining TTL, renew / stop buttons. Services are automatically reclaimed when their TTL expires (guarding against "started it and forgot to shut it down").

<Note>
  Playground is a configurable feature that admins can open up by role; the slurm backend does not support it yet (training nodes usually have no inbound network). See the [Playground guide](/en/guides/playground) for full semantics.

<Warning>
  Playground does not provide a long-term availability contract or a stable client endpoint. Do not connect production or durable internal applications to it.
