# Quick Start

> Run your first Playground experiment in 5 minutes

This quickstart helps you run a single prompt, compare models, and save a reusable chat session.

## Step 1: Open Playground

1. Sign in to Bud Admin.
2. Click **Playground** from the left navigation.

```mermaid theme={null}
sequenceDiagram
    participant U as User
    participant A as Bud Admin
    participant P as Playground
    U->>A: Open Playground
    A->>P: Load embedded session
    U->>P: Select model
    U->>P: Send prompt
    P-->>U: Stream response + metrics
```

## Step 2: Start a Single-Model Chat

1. Choose a model/endpoint in the selector.
2. Enter a prompt (example: "Summarize this support ticket in 3 bullet points").
3. Click **Send**.
4. Observe output quality and latency.

## Step 3: Tune Generation Settings

Open **Settings** and modify:

* Temperature
* Response length/token limit
* Repeat penalty
* Stop strings

Run the same prompt again to compare behavior changes.

## Step 4: Compare Models

1. Open a new chat window/pane.
2. Select a second model.
3. Reuse the same prompt in both panes.
4. Compare response quality, consistency, and speed.

## Step 5: Save and Revisit

1. Keep the session in chat history for later review.
2. Use message-level controls (copy/edit/retry/feedback) to iterate.

  Use the same prompt template across models to make comparisons fair and repeatable.
