Để tạo cho blog đẹp và đồng nhất về hình ảnh, mình có nghiên cứu một số prompt để tạo cho nhanh. Nói chung cũng phải test đi test lại vài lần mới tìm được ảnh ưng ý chứ không phải một phát là ăn ngay nha. Bạn nào có tham khảo thì có thể copy về và tinh chỉnh lại cho phù hợp. Mỗi ảnh tốn khoản 1000 VND đến 1300 VND khi sử dụng NanoBanana.
