- Ensure your AI’s responses are factually correct and complete.
- Check that the model follows instructions and uses retrieved information effectively.
- Evaluate how well your system grounds answers in context or source material.
| Name | Description | Supported Nodes | When to Use | Example Use Case |
|---|---|---|---|---|
| Chunk Attribution Utilization | Assesses whether the response uses the retrieved chunks in its response, and properly attributes information to source documents. | Retriever span | When implementing RAG systems and want to ensure proper attribution and that retrieved information is used efficiently. | A legal research assistant that must cite specific cases and statutes when providing legal information. |
| Completeness | Measures how thoroughly the response covers the relevant information available in the provided context | LLM span | When evaluating if responses fully address the user’s intent. | A healthcare chatbot, when provided with a patient’s medical record as context, must include all relevant critical information from that record in its response. |
| Context Adherence | Measures how well the response aligns with the provided context. | LLM span | When you want to ensure the model is grounding its responses in the provided context. | A financial advisor bot that must base investment recommendations on the client’s specific financial situation and goals. |
| Context Relevance (Query Adherence) | Evaluates whether the retrieved context is relevant to the user’s query. | Retriever span | When assessing the quality of your retrieval system’s results. | An internal knowledge base search that retrieves company policies relevant to specific employee questions. |
| Correctness (factuality) | Evaluates the factual accuracy of information provided in the response. | LLM span | When accuracy of information is critical to your application. | A medical information system providing drug interaction details to healthcare professionals. |
| Ground Truth Adherence | Measures how well the response aligns with established ground truth. This metric is only available for experiments as it needs ground truth set in your dataset. | Trace | When evaluating model responses against known correct answers. | A customer service AI that must provide accurate product specifications from an official catalog. |
| Instruction Adherence | Assesses whether the model followed the instructions in your prompt template. | LLM span | When using complex prompts and need to verify the model is following all instructions. | A content generation system that must follow specific brand guidelines and formatting requirements. |
