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.
Which file format should you use?
- A. CSV
- B. TSV
- C. JSONL Correct
- D. JSON
Explanation
Fine-tuning training and validation data must be JSON Lines (JSONL) files, with one complete training example (for chat models, a messages array) per line. CSV and TSV are not accepted for fine-tuning uploads, and a single JSON document is not the line-delimited format the service expects.
