Best model for up-to-date data

Hello - I started using Perplexity's API after having some success using the UI product. However, I'm finding that the API models are returning pretty outdated information. For example, when querying for information about Linda Yaccarino, the API models (including the llama 3, large, online model) identify her as the CEO of NBC universal, which is over a year out of date. However, querying Perplexity using the UI clearly identifies her as the CEO of X (correctly) and is able to report sources from the same day.

Is there another model I can reference via the UI to get more up to date information, or another way I need to parametrize the API to get more up to date information? Thanks!
