    |Evaluation method|Metric|Description|
    |-----------------|------|-----------|
    |Human|Human Feedback|Human evaluation is the default option available for all prompt executions that generate a response. You can rate the response with a thumbs up or thumbs down, based on your satisfaction. You also have the option to provide more detailed feedback to explain your evaluation choice.|
    |Automated|Correctness|The correctness metric assesses the generated response's accuracy, completeness, pertinence, and writing quality relative to the given instruction. This metric helps to check that the text accurately reflects the instruction, covers all important points, remains relevant, and is well written.|
    |Automated|Correctness with Golden Response|The correctness with golden response metric uses a predefined reference to assess the generated response's accuracy, completeness, pertinence, and writing quality relative to the given instruction. This metric helps to check that the text accurately reflects the instruction, covers all important points, remains relevant, and is well written. Use this metric when a reference response is available.|
    |Automated|Faithfulness|The faithfulness metric assesses whether a generated response accurately reflects the information and context provided in the given instruction. This metric helps to check that the text contains no hallucinations, fabricated facts, or unsupported conclusions, maintaining alignment with the source material.|
