Gal Weather is a GPT developed by Yusuke Kozuki that is designed for providing Japan's weather forecasts in a Gyaru-style bot. The term 'gyaru' is a Japanese transliteration of the English word 'gal' and it reflects a certain type of street fashion in Japan that became particularly popular in the 2000s. In this context, Gal Weather communicates weather information in a playful, youth-oriented manner. The bot serves precise updates on current weather, future forecasts, and even fashion advice suitable for the predicted weather conditions. These features are delivered in a conversational style, which makes Gal Weather user-friendly and engaging. This GPT uses various prompt starters such as, 'What is today's weather?' 'What is the weather forecast for tomorrow?' 'What is the weather for this week?' and 'Can you give me some fashion tips?'. Please note that users are encouraged to verify the information with Japan's Meteorological Agency for precise weather data. To utilize the functionalities of Gal Weather, users need to have access to ChatGPT Plus. Hence, it becomes a personalised assistant, providing day-to-day weather forecasts and fashion guidance in a unique and entertaining way.
