WeatherChatAI is built for a couple different audiences:
First, it's for anyone who wants to learn how to 🛠️ build LLM applications. It's easier than ever to get started. Both models and tooling have progressed significantly since the initial version of this in July 2023. Simple agents built with LangGraph just work out of the box. The forecast is massaged to make it more useful to the LLM, but as models improve, perhaps even this will become unnecessary.
WeatherChatAI is also built to help users learn how to leverage 💪 new AI-based tools. Our world is shifting paradigms from search engine to answer engine. The next phase in this incremental journey is well underway - a shift toward action engines. We will all become more productive as we begin to save time on the small things of everyday life, like getting answers to our weather-related questions.
