Experiments

Test and validate your LLM applications

Experiments help developers systematically test changes in their LLM applications using a curated dataset. Each experiment run is stored independently to measure the impact of changes over time.

Quickstart: Experiments

Key features

1. Run experiments in the UI or with our experiments SDK
2. Evaluate your experiment runs
3. Set up CI/CD pipelines
4. Download your experiment data

Components of an Experiment:

Datasets

Datasets

A dataset is a collection of examples for evaluating your application. It is commonly represented as a pandas Dataframe, which is a list of dictionaries. Those dictionaries can contain input messages, expected outputs, metadata, or any other tabular data you would like to observe and test.

Tasks

Run experiments

A task is any function that you want to test on a dataset. Usually, this task replicates LLM functionality.

Evaluators

Evaluate experiment with code

An evaluator is a function that takes the output of a task and provides an assessment.

It serves as the measure of success for your experiment. You can define multiple evaluators, ranging from LLM-based judges to code-based evaluations.
