This guide outlines the available methods to rename an experiment in the LangSmith UI. There are two ways to rename an experiment:
  1. Within the Playground
  2. Within the Experiments View
Note that experiment names must be unique per workspace.

​
1. Renaming an experiment in the Playground

When running experiments in the Playground, a default name with the format pg::prompt-name::model::uuid (eg. pg::gpt-4o-mini::897ee630) is automatically assigned. You can rename an experiment immediately after running it by editing its name in the Playground table header. Edit name in playground

2. Renaming an experiment in the experiments view

When viewing results in the experiments view, you can rename an experiment by using the pencil icon beside the experiment name. Edit name in experiments view
