Kudzika Kwakadzika
Direct Preference Optimization (DPO) skips training a separate reward model: given preferred and rejected responses, it adjusts the policy with a classification-style loss derived from the RLHF objective. Vanilla DPO trains on a fixed dataset, which may become off-policy as the model changes. Iterative DPO closes the loop: the current policy samples responses, human raters or an AI judge compare them, and the next DPO update trains on these fresh pairs. Repeating rounds incurs additional sampling and labeling costs. If the model judges its own outputs, its judgments can also inherit its biases, so independent checks and held-out evaluation remain useful.

Ramangwana reIterative DPO uye Online Preference Tuning
Preference tuning can become more continuous and automated, but each round depends on the judge’s reliability, data coverage, and evaluation that is not reused as training signal. Self-rewarding systems need checks for self-confirming errors, and online cycles need cost and quality measurement at every iteration.
