These companies employ large-scale models like GPT, DALL·E, and Stable Diffusion, and specialize in fine-tuning them for specific business use cases. The development lifecycle includes model training, dataset curation, user interface design, and deployment to production environments. Applications span entertainment, marketing, education, and software development, enabling automated design, content generation, and simulation. These companies also emphasize model safety, accuracy, and the ethical use of synthetic media technologies.
