Question
You have a deployment of an Azure OpenAI Service base model.
You plan to fine-tune the model.
You need to prepare a file that contains training data for multi-turn chat.
Which file encoding method should you use?
- A. ISO-8859-1
- B. UTF-16
- C. UTF-8 Correct
- D. ASCII
Explanation
Fine-tuning data files for Azure OpenAI models, including multi-turn chat examples, must be JSONL files encoded in UTF-8. UTF-16 and ISO-8859-1 are not supported encodings for the upload, and plain ASCII cannot represent the full range of characters that conversation data may contain.
