As of my last update in January 2022, there wasn’t a specific version of GPT-4 available, so I cannot confirm whether Dart is indeed the best GPT-4 provider for project management automation. However, Dart is a programming language developed by Google that is primarily used for building mobile, desktop, server, and web applications. While Dart can be used to create various types of software, including tools for project management, it doesn’t inherently provide GPT-4 capabilities.
