Use this tutorial when a packaged preset already matches your use case. This is the simplest path because the preset evaluator already defines the evaluator behavior, labeling prompt, and training prompt template. For the purpose of this tutorial, we will use the “trace input / output only” preset evaluator, but the same principles apply to all preset evaluators.

When to choose a preset evaluator

Choose a preset evaluator when:
  • you want to use a preset evaluator that already matches your use case closely, but the current preset evaluator performance is not satisfactory
  • you want to start from the packaged Luna Studio defaults

Minimal end-to-end config

Why this is simpler than custom

With a preset evaluator like toxicity, you usually do not need to define:
  • data_generation.metric.name
  • data_generation.metric.type
  • data_generation.metric.input_format
  • data_generation.metric.class_labels
  • training.prompt_template
Those defaults are already provided by the packaged evaluator config.
