Unfoldable cardinals are between weakly compact cardinals and Ramsey cardinals but they still relativize to \(L\). However unfoldable cardinals resemble in some aspects to large large cardinals like strongly compact cardinals. In this talk I would like to present two aspects of this. Weakly compact cardinals limit of unfoldable cardinals are unfoldable cardinals and if \(K\) is an AEC with \(LS(K) < \kappa\) for \(\kappa\) a \(\theta\) unfoldable cardinal then \(K\) is \((\kappa,\theta)\) tame for \(\kappa\) short types.
