Create a sleek and modern cover image for a website specializing in AI virtual assistants. The design should have a sophisticated and minimalistic style, featuring a blend of soothing blues and subtle hints of pink. The colors should transition smoothly to ensure there is enough contrast for text to be clearly readable over the image. Incorporate abstract elements or subtle tech-inspired graphics to represent artificial intelligence and virtual assistance, while keeping the overall aesthetic elegant and professional. Ensure that the color transitions are gentle and not too stark to maintain a cohesive look with the ability to overlay text.
