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.
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. If you'd like to see additional support or have other questions, let us know in our Discord or by filling out this contact form.
