# Stax [Get started with Stax](https://stax.withgoogle.com) Ship your LLM powered apps faster and with greater confidence. Stax removes the headache of AI evaluation by letting you test models and prompts against your own criteria. [Video](https://www.youtube.com/watch?v=ANpQEc_fWUU) ## Core features - **Manage and Build Test Datasets**: Import production datasets or use Stax to construct new ones by prompting any major LLM. - **Leverage Pre-Built and Custom Evaluators**: Use a suite of default evaluators for standard metrics like instruction following and verbosity, or create custom ones to test for nuanced qualities like brand voice or business logic. - **Make Data-Driven Decisions**: Get actionable data on quality, latency, and token count to identify an effective AI model, prompt, or iteration for your application. Stax supports text-based calls to models, with image support coming soon.
