customize the language

Good morning everyone, with Firefly I have created some really beautiful images. Even if I realize that it cannot be done for free, there should be the possibility of training your "firefly" with the language and syntax of each user in correspondence with an image. for example: an image that represents a dog, which we call dog.jpg and a txt file that I call dog.txt with the description of the image inside, so my firefly learns how a certain user thinks and writes. I am trying to do something similar in "lora trainer" but I can't get the same quality as Firefly. I use several generative AI tools, including lesser-known tools like Tydiffusion, but the image quality and result/prompt correspondence that I have with firefly I have not obtained with any other tool, can I send you the images created? Thanks for the time you have dedicated to me. Filippo
