[Vitalik: Mobile Offline Local Knowledge Applications Still Struggle with Complex Problems] Odaily Planet Daily News - Vitalik posted on the X platform that he is testing mobile offline local knowledge applications built by developers. Compared to the applications he attempted to build two months ago, these have seen improvements, but their speed and performance on complex problems still fall short of models that can run on laptops. Their performance is particularly weak in professional travel-related queries, such as finding the best vegan restaurant in the city one is visiting. He hopes such applications will continue to improve, enabling users to access various factual information without needing to connect to the internet.
