​
Intro

The CLI is a tool for interacting with the Vals.ai platform from the command line. It’s good for simple workflows, such as running a test suite or pulling a run, but for more complex workflows, it’s recommended to use the SDK.

​
Install

pip install valsai

​
Authentication

Make an account at platform.vals.ai and confirm your email. To authenticate with the CLI, go to the Admin page of the console, and create an API key. Next, in your environment, run the following: 
export VALS_API_KEY=<YOUR API KEY>
To make this permanent, add it to your ~/.zshrc / ~/.bashrc. If you are using a method other than environment variables to manage your credentials, you can also set the API key with the following line of python code: 
from vals.sdk.auth import configure_credentials

configure_credentials(api_key = MY_API_KEY)
Ensure that you never commit any credentials to any version control system such as Git.

​
Overall Usage

The CLI is run as follows: 
$ vals
Use the --help flag at the top and subcommand level for guidance. Commands must be run from the pip environment the cli was installed in. Commands are split up into subcommands. Currently, there are two subcommands:
  • vals suite: relating to creating / updating tests and suites
  • vals run: relating to creating and querying runs and run results.
  • vals rag: Relating to RAG workflows (see the RAG Debug page for more information)

​
Creating, Modifying, and Viewing Test Suites

You can create a test suite from JSON file. The file is the same format as the one used in the SDK. 
vals suite create ./example_suite.json
The vals suite create commands will produce a link to the created test suite. To update a test suite, the workflow is similar, but you should provide the id of the test suite you want to update. 
vals suite update ./example_suite.json <test_suite_id>
To pull a test suite locally (either to CSV or JSON), you can use the vals suite pull command. 
vals suite pull ./test_suite.csv <test_suite_id> --csv

vals suite pull ./test_suite.json <test_suite_id> --json
To list all test suites, you can use the vals suite list command. 
vals suite list

​
Running a Test Suite

To run a test suite, you can use the vals suite run command. 
vals suite run <test_suite_id> --model openai/gpt-4o-mini
There are a number of optional flags you can provide to the command, in addition to the model flag:
  • --wait_for_completion: Wait for the run to complete before exiting the command.
  • --run-name: Provide a name for the run for easy identification.
  • --eval-model: Model to use as the LLM-as-judge.
To see the full list of flags, do 
vals suite run --help

​
Viewing and Querying Completed Runs

To list all of the runs you’ve done, you can use the vals run list command. 
vals run list
You can also view only runs for a single test suite: 
vals run list --test-suite-id <test_suite_id>
You can pull the data for a single run similarly to how you pull a test suite: 
vals run pull <run_id> my_run.json --json
Or, to pull as CSV: 
vals run pull <run_id> my_run.csv --csv
