Originally created by @PlebeiusGaragicus on GitHub (Aug 10, 2024).

While working on LangGraph agents I noticed a new and useful feature in LangGraph Studio where configurable options can be given as a discrete list of possibilities.

Link to code example

# Define the config
class GraphConfig(TypedDict):
    model_name: Literal["anthropic", "openai"]

This code now tells LangGraph Studio to display these as a nice list in the UI.

I'm requesting that we also have the Pipelines Valve UI display a list of options as defined in the pipeline code itself. After looking through the examples I haven't noticed if this has been implemented yet and it would be very helpful.

this is already possible:

class Pipeline:
    class Valves(BaseModel):
        MODEL_NAME: Literal["anthropic", "openai"]

I can't seen to dynamically load a Literal type at runtime.

Is there a way to dynamically set a value on pipeline init?

Hi @PlebeiusGaragicus did you find a way to dinamycally add literals? It would be a really nice addition for example for model ids in valves

@Haervwe no I’ve just about moved on. I’m not confident I can get a LangGraph agent working with open webui just yet and that was my use case. But they’re really cooking so I’m hopeful. Agents are the way…! OUI is getting closer
