You can use any LLM you wish with Langkit, as long as you provide the prompt and response columns. There are, however, two modules that require additional LLM calls to calculate metrics: `response_hallucination` and `proactive_injection_detection`.

Azure-hosted OpenAI models are also supported through `OpenAIAzure`. + +--- + **Q**: Can I choose individual metrics in LangKit? **A**: The finest granularity with which you can enable metrics is by metric namespaces. For example, you can import the `textstat` namespace, which will calculate all the text quality metrics (automated_readability_index,flesch_kincaid_grade, etc.) defined in that namespace. You can't, for example, pick the single metric `flesch_kincaid_grade`. diff --git a/langkit/docs/modules.md b/langkit/docs/modules.md index 237e9f1d..4817880f 100644 --- a/langkit/docs/modules.md +++ b/langkit/docs/modules.md @@ -18,7 +18,7 @@ The `hallucination` namespace will compute the consistency between the target response and a group of additional response samples.
