# Try a sample

Source: https://redcrown.ai/docs/guides/try-a-sample/

See a proof in one step with a public sample, no data, no keys, no account.

## 1. Pick a sample

Choose one of the built-in sample tasks. RedCrown runs it against a set of public models and returns a ranked proof.

**UI**

Open **Prove** (`/`). Under the task input, choose a sample task from the sample picker. No login is required.

**CLI**

```
redcrown eval --sample summarize
```

The `--sample` flag accepts `extract`, `classify`, or `summarize`.

**MCP**

Call `try_sample`. The `task` argument is optional and defaults to `transcribe`:

```
{
  "task": "transcribe"
}
```

## 2. Read the proof

The ranked report shows each candidate model, its score, cost, and whether it clears the quality bar. The winner is the cheapest model that clears.

**UI**

The ranked report renders inline on the Prove page. Each row shows the model name, quality score, cost, and a winner badge on the cheapest model that clears the bar.

**CLI**

The ranked report prints to the terminal. Add `--report-json out.json` to save the full receipts to a file:

```
redcrown eval --sample summarize --report-json out.json
```

**MCP**

`try_sample` returns a `proof_url` pointing to the public ranked report. Share it or open it directly.
