Résumé
Its behavior depends on the preference data, objective settings, and implementation.
Plongeur bu xóot
Odds Ratio Preference Optimization starts with supervised fine-tuning on preferred responses and adds a penalty that contrasts the policy’s odds for chosen and disfavored responses. This monolithic objective avoids a separate reference model and a distinct preference-optimization phase. The paper describes the objective as a way to apply preference alignment during SFT; it does not mean that every data pipeline or implementation uses no auxiliary components. The odds transformation produces a different penalty shape from a raw log-probability difference. Outcomes depend on the preference dataset, coefficient, base model, and evaluation. ORPO is a training method, not an inference-time decoding rule or a guarantee that preferences are faithfully represented.

What is Odds Ratio Preference Optimization?
ORPO combines supervised fine-tuning with an odds-ratio preference penalty in one training phase and does not require a separate reference model. Its behavior depends on the preference data, objective settings, and implementation.

What form does an ORPO preference example contain?
ORPO uses chosen and rejected responses for the same prompt to form its preference comparison.
How does ORPO convert a response probability p into odds?
Odds are computed as p/(1−p); ORPO applies this transformation when forming its preference term.
