Content Trend of the Month:

Users are exploring the new features, and Studio Ghibli-style images created with ChatGPT-4o are everywhere, becoming a popular content strategy. However, this has also sparked criticism against the platform, with some pointing out the environmental cost of generating these AI images. It’s said that converting a single image into the Ghibli style uses the water equivalent of 17 glasses.
