OpenAI now allows developers to customise GPT-3 models

OpenAI is making it easy for developers to "fine-tune" GPT-3, enabling custom models for their applications. The company says that existing datasets of "virtually any shape and size" can be used for custom models. A single command in the OpenAI command-line tool, alongside a user-provided file, is all that it takes to begin training. The custom GPT-3 model will then be available for use in OpenAI's API immediately. One customer says that it was able to increase correct outputs from 83 percent to 95 percent through fine-tuning.
