# Playground Concepts

> Understand sessions, chats, and model comparison in Playground

## Mental Model

Playground is organized around reusable sessions and chat panes where each pane can target a different model.

    A[Project Context] --> B[Playground Session]
    B --> C[Chat Pane A]
    B --> D[Chat Pane B]
    C --> E[Model/Endpoint A]
    D --> F[Model/Endpoint B]
    E --> G[Responses + Metrics]
    F --> G
```

## Key Concepts

### Session

A session is your working container for one or more chats. It stores prompt/response history and settings context.

### Chat Pane

A pane is an individual conversation track. Multiple panes enable side-by-side model testing.

### Model Binding

Each pane is bound to a selected model or endpoint. Rebinding lets you test alternatives quickly.

### Prompt Iteration

Prompts evolve through edit/resend, retry, and parameter tuning. Keep prompts stable when benchmarking models.

### Response Signals

Use output quality, style adherence, latency, and token usage to evaluate model fit.

## Common Workflows

1. **Single model drafting**: refine one prompt until output quality is acceptable.
2. **Comparative evaluation**: run identical prompts in multiple panes.
3. **Preset validation**: validate default generation settings for team-wide reuse.

## Operational Guidelines

<Check>Prefer short, deterministic prompts first; add complexity after baseline checks.</Check>
<Check>Record winning prompts and settings in team docs for repeatability.</Check>
<Check>Use consistent evaluation criteria (accuracy, tone, latency, safety).</Check>
