[**OpenAI**](https://www.ai-360.online/openai/) **has announced improvements to its Fine-Tuning API and the expansion of its Custom Models Program. The enhanced Fine-Tuning API allows users to fine-tune OpenAI's powerful language models on their own data, enabling the creation of custom AI applications with unprecedented accuracy and efficiency. With just a few lines of code, developers can now train models that understand the nuances of their specific domain, resulting in more relevant and accurate outputs.**

"Our improved Fine-Tuning API is a game-changer for businesses looking to harness the power of AI," said Sarah Johnson, Head of Product at OpenAI. "By making it easier than ever to create custom AI models, we're democratising access to cutting-edge technology and helping companies solve complex problems faster."

OpenAI has expanded its Custom Models Program, which provides select partners with access to even more advanced AI capabilities. The program now includes a wider range of industries, from healthcare and finance to education and entertainment.
