FAQ
How does traffic splitting work?
You define two or more prompt variants and assign traffic weights. Our API proxy intercepts your LLM calls and routes each request to a variant, logging the outcome for analysis.
What counts as a conversion?
You define it — a thumbs-up, a completed checkout, a low latency response, or any custom event you send to our tracking endpoint.
When is a winner declared automatically?
When one variant reaches 95% statistical significance over the other using a two-proportion z-test, the system flags it and can optionally promote it to 100% traffic.
