Microsoft Azure OpenAI has announced support for fine-tuning of data for models such as GPT-3.5-Turbo, Babbage-002, and Davinci-002. Developers can now train personalized ChatGPT instances using their own datasets, such as for medical assistants. Fine-tuning enhances the accuracy and security of content, addressing the challenge of efficient data utilization. Microsoft offers detailed fine-tuning tutorials and managed services to reduce resource costs. Models like GPT-3.5-Turbo provide a high-performance foundation for fine-tuning.
