Env variables

​

Reason

If you use LLM node, for authentication, you will need to specify your own API keys to Laminar, so that Laminar can make calls to these APIs. For example, if you use LLM node with “gpt-4o-mini” model, then you’ll need to specify OPENAI_API_KEY in “env variables” page.

​

Setting up

​

Quick set up

If your current pipeline requires env variables, you can set up just the required ones in the pipeline page itself.

​

Full set up

First, navigate to “env variables” page, using the navigation on the left of the screen.

To add a key do the following:

1. Press “Add variable”
2. Select a pre-defined variable name or add a custom one.
3. Enter the value.
4. Press “Add” in the dialog.

Note that some nodes, such as, for example, LLM node, have pre-defined env variables. For other nodes, if there’s an option in a pipeline builder’s particular node to set a name for env variable, you can set it on the node and add a custom variable with such name.

​

Pre-defined env variables

OPENAI_API_KEY, ANTHROPIC_API_KEY, MISTRAL_API_KEY, GROQ_API_KEY, etc.

​

Safety

Laminar never stores your env variables. The keys are stored in your browser’s storage and are used for pipeline runs in the “pipelines” page and evaluation jobs, triggered manually by the user.

When you call an Endpoint, the variables set in this page are not used. When you call pipeline as an API endpoint, you’ll need to pass env in the payload. See api reference for more information.
