# Test your AI (anonymous)

Anonymous prompt-against-model sandbox on Stratix Public — no signup, rate-limited.

The Stratix Public sandbox lets you run a single prompt against a model without signing up. It's the fastest way to build intuition about a model's behavior.

## How it works

1. Pick a model from the catalog
2. Enter a system message and a user prompt
3. Run
4. See the response, latency, and (where available) token usage

## Limits

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

## When to upgrade to Premium

When you need:

* Persistent results
* Scoring (deterministic + LLM judges)
* Running against a dataset, not one prompt at a time
* Comparing many models in one job
