Subsets Monitor

You can configure the model, the prompt template, and the criteria

The model​

You can choose any model available in the dropdown.

The prompt template​

You can customize the prompt template to be whatever you want. The prompt template is a LangChain prompt template - this means that anything in {...} is treated as a variable to format. There are two permitted variables: input and output, corresponding to the input and output of the run you are evaluating

The criteria​

An evaluator will attach arbitrary metadata tags to a run. These tags will have a name and a value. You can configure this in the Criteria section. The names and the descriptions of the fields will be passed in to the prompt.

How to set API keys​

Online evaluation uses LLMs. In order to set the API keys to use for these invocations, navigate to the Settings -> Secrets -> Add secret page and add any API keys there.
