# How Fat Tony works

Browse public model information, create an account, select a race and ask a question. A free account includes six questions in a rolling 24-hour window.

Fat Tony combines specialised horse racing machine learning models with conversational analysis. The models estimate WIN and PLACE probabilities; race conversations help explain the available form and race context.

Practise in the virtual Sandbox and Totalizers. No real-money wagers are accepted. Race information and account features may require sign-in.
