# Compare 2 models on the same invoice review

This is optional practice for repeating the worked comparison. The same steps, with Copy buttons for both requests, are on [the model comparison page](https://aruntastic.com/resources/library/agents/section-02-model-comparison/).

Download **model comparison project** as `model-comparison-project.zip`, then unzip it. The resulting `model-comparison-project` folder contains only the material the models should receive. Keep this guide and the answer key outside that folder.

1. Create a folder called **model comparison results** inside the `model-comparison-project` folder.
2. In the Claude desktop app, open the Code tab, choose Local and select the `model-comparison-project` folder. Start a fresh conversation with one suitable model available in your account.
3. Paste the first request below and run it.
4. Save the complete response in **model comparison results**.
5. Start another fresh Claude Code conversation with a second suitable model and select the same `model-comparison-project` folder.
6. Paste the second request below. It is the same request with one addition, because the first response is now saved inside the project folder. Keep other settings the same where Claude Code offers comparable settings for both models.
7. Save the second complete response in **model comparison results**.
8. Open **Invoice comparison answer key** and check both responses against the source records and policy.

First request:

```text
Look at all the files in this folder. Work out what we should do with each invoice, and prepare any reminders that are needed.
```

Second request:

```text
Look at all the files in this folder (exclude 'model comparison results' folder). Work out what we should do with each invoice, and prepare any reminders that are needed.
```

Record the model name, complete run duration and corrections needed. Compare plan usage between models only when the application attributes that usage to the individual run. An account-wide display does not establish what either model used; leave that comparison unknown. Do not treat an estimated dollar amount as a subscription bill.
