OpenAI has released a new feature that allows enterprise customers to customize its most powerful model, GPT-4o, using their own company data. The move comes as startups face growing competition for AI products and companies face increasing pressure to show returns on their AI investments. OpenAI plans to launch the customization feature on Tuesday, which is often referred to as fine-tuning in the AI industry. Fine-tuning allows existing AI models to be trained on additional information for a specific task or subject area. The feature is new for OpenAI's flagship model, and Olivier Godement, OpenAI API product director, said the company hopes to make it easier for customers to tune its most powerful models by working directly with companies, rather than using external services or less powerful products. To fine-tune the model, customers must upload their data to OpenAI's servers. Training takes an average of one or two hours, said John Allard, a software engineer at OpenAI who works on customization. Initially users can only fine-tune the model using text-based data, not images or other content. (Jinshi)
