According to Odaily Planet Daily, OpenAI has released a new feature that allows corporate customers to customize its most powerful model GPT-4 with their own company data. The move comes as startups face increasing competition in artificial intelligence products and companies face increasing pressure to show the benefits of artificial intelligence investments. OpenAI plans to launch the customization feature on Tuesday, which is often referred to as fine-tuning in the artificial intelligence industry. Fine-tuning allows existing artificial intelligence models to be trained on additional information for specific tasks or subject areas. This feature is new to OpenAI's flagship model, and Olivier Godement, OpenAI API product director, said the company hopes to make it easier for customers to adjust its most powerful models by working directly with companies, rather than using external services or less powerful products. In order to fine-tune the model, customers must upload their data to OpenAI's servers. John Allard, a software engineer working on customization at OpenAI, said training takes an average of one or two hours. Initially, users can only fine-tune the model using text-based data, not images or other content.
