Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Plain text file with one prompt-completion pair per line separated by a tab

    Why it's wrong here

    Plain text is not a supported format for OCI GenAI fine-tuning.

  • ✗

    Parquet file with a 'text' column containing concatenated prompt and completion

    Why it's wrong here

    Parquet is not the required format; JSONL with specific keys is needed.

  • ✗

    CSV with columns 'input' and 'output'

    Why it's wrong here

    CSV is not the required format; JSONL is expected.

  • ✓

    JSONL with each line containing 'prompt' and 'completion' keys

    Why this is correct

    The training dataset must be a JSONL file where each line is a JSON object with 'prompt' and 'completion' fields.
