Want to name your test runs? Here's how!

You can easily name LangSmith test projects by setting the project_name parameter. We recommend including a string identifier for the model/variant you are testing, along with a time-based component so that you can easily tell your test runs apart, e.g."\<prompt-123\> {timestamp}". For example:

project_name = f"improved_chain {'%Y-%m-%d %H:%M:%S')}"

results = client.run_on_dataset(

This will result in named runs like so:
