Researchers have developed a new Bayes-assisted framework for constructing confidence sequences, which offer time-uniform uncertainty quantification for bounded means. This method uses a Bayesian predictive model to adaptively select martingale updates that maximize predictive log-growth, ensuring validity even with misspecified priors. The procedure is proven to be asymptotically log-optimal under Wasserstein consistency, matching oracle procedures. Experiments demonstrated that informative priors can significantly narrow confidence intervals and reduce sampling needs, with applications including LLM evaluation. AI
