Our metrics have explainability built-in, helping you understand which parts of the input or output are leading to certain outcomes. We have two types of explainability: Highlighting and generated Explanations.

Explainability via Token Highlighting

When looking at a workflow in the expanded view, some metric values will have an

icon next to them. Clicking on it will turn token-level highlighting on the input / output section of the node.

The following metrics have token-level highlighting:

Explainability via Explanations

For metrics powered by Chainpoll, we provide an explanation or rationale generated by LLMs. 🪄 next to metric values indicate that this metric has an explanation available. This explanation will include the reasoning the model followed to get to its conclusion. To view the explanation, simply hover over the metric value.
