Social Media Codysseus could leverage the large and diverse corpus of his own written and spoken content to train a custom model that captures his unique voice and style. He could also use additional data sources, such as feedback from his audience, social media interactions, and relevant top- ics and trends, to further refine and update his model. By fine-tuning GPT-4 on his own data, Codysseus could potentially generate new content that is consistent, coherent, and creative, and that reflects his personality and preferences. He could also use his model to interact with his fans, answer questions, and provide commen- tary on various issues. However, Codysseus would also need to be careful and ethical in using his model, and ensure that he discloses and acknowledges the use of GPT-4 to his viewers and followers. He would also need to monitor and evaluate his model’s outputs, and correct any errors, biases, or inaccuracies that might arise. More- over, he would need to respect the intellectual property and privacy rights of others, and avoid plagiarizing or misrepresenting any sources or information. Finally, he would need to maintain his own authenticity and integ- rity, and not rely solely on his model to express himself or engage with his community. In short, it’s quite possible that someone like Codysseus could do this already. It would take him some time and effort to arrange all his source data—the YouTube transcripts, blog posts, etc.—into the format that the fine-tuning process requires. At that point, though, he’d be able to use the resources OpenAI provides at extremely low cost. (In Codysseus’ hypothetical case, OpenAI would prob- ably charge him around $30 for its fine-tuning process.) 107
