Frequently Asked Questions
How does automatic winner detection work?
PromptSplit continuously monitors your experiment metrics and applies statistical significance testing. Once a variant reaches 95% confidence with enough sample size, it automatically promotes the winner and stops routing traffic to losing variants.
Which AI providers are supported?
PromptSplit is provider-agnostic. It works with OpenAI, Anthropic, Mistral, Cohere, and any API-based model. You define the prompt variants; we handle the routing and tracking.
Can I define custom success metrics?
Yes. You can track built-in metrics like latency, token cost, and thumbs-up ratings, or send custom conversion events via our API to measure whatever matters most to your product.
