Frequently Asked Questions
What counts as a test run?
A test run is a single prompt evaluation against a specific model endpoint. If you run a suite of 10 prompts, that counts as 10 test runs. Retries due to rate limits are not counted.
Can I switch plans at any time?
Yes. You can upgrade or downgrade your plan at any time. When upgrading, you get immediate access to new features. When downgrading, the change takes effect at the end of your current billing period.
Do you offer annual billing?
Yes. Annual billing is available for Pro and Enterprise plans with a 20% discount compared to monthly billing. Contact our sales team for details.
What models do you support?
PromptReliability Labs works with any LLM accessible via API, including OpenAI, Anthropic, Google, Mistral, and self-hosted models. If you can call it, we can test it.
Is there a free trial for the Pro plan?
Yes. Every new account starts with a 14-day free trial of Pro features. No credit card required. If you don't upgrade, you'll automatically move to the Starter plan.
How does the CI/CD integration work?
We provide GitHub Actions, GitLab CI, and generic webhook integrations. Add a single step to your pipeline that runs your prompt test suite and blocks the deploy if quality scores drop below your defined thresholds.
