# Test your AI

Test a model on a prompt anonymously — no signup required.

Stratix Public includes a quick sandbox: pick a model, paste a prompt, see the response. Use it for ad-hoc model intuition; use Premium for anything you want to track.

## Steps

### 1. Open the sandbox

Go to [`stratix.layerlens.ai`](https://stratix.layerlens.ai) and open the **Test your AI** entry from the top nav (or model page).

### 2. Pick a model

Search and select.

### 3. Paste your prompt

Free-form text input. System message and user message both supported.

### 4. Run

Click **Run**. Response appears below.

### 5. Try another model

Switch models and rerun the same prompt; compare responses.

## Limits (anonymous)

* Rate-limited per IP — fine for ad-hoc, not for batch
* No persistence — close the tab and the run is gone
* No metrics, no scoring — just the response

## When to upgrade to Premium

When you want to:

* Persist results to a workspace
* Score responses (deterministic + LLM judges)
* Run against a dataset, not one prompt at a time
* Compare across many models in one job
* Save and re-run
