[Vitalik: Significant Progress in Mobile Offline Knowledge Applications, but Still Inferior to Laptop Models for Complex Problems] Ethereum co-founder Vitalik Buterin posted on the X platform, stating that he recently tested some local knowledge applications that can run offline on mobile devices. Compared to the version he attempted to build himself two months ago, these applications have made noticeable progress. However, when it comes to handling complex problems, their speed and effectiveness still fall short of models that can run on laptops. Vitalik noted that these applications currently perform weakest in specialized travel queries, such as answering questions like 'What is the best vegetarian restaurant in my city?' He expressed hope that these products will continue to improve, envisioning a future where users can conveniently query various real-world information they care about without needing an internet connection.
