Overview

Argilla

Argilla is a collaborative annotation tool for AI engineers and domain experts who need to build high-quality datasets for their projects.

Getting Started

To log the data to Argilla, first you need to deploy the Argilla server. If you have not deployed the Argilla server, please follow the instructions here.

Next, you will need to configure and create the Argilla dataset.


client = rg.Argilla(api_url="<api_url>", api_key="<api_key>")

settings = rg.Settings(
    guidelines="These are some guidelines.",
    fields=[
        rg.ChatField(
            name="user_input",
        ),
        rg.TextField(
            name="llm_output",
        ),
    ],
    questions=[
        rg.RatingQuestion(
            name="rating",
            values=[1, 2, 3, 4, 5, 6, 7],
        ),
    ],
)

dataset = rg.Dataset(
    name="my_first_dataset",
    settings=settings,
)

dataset.create()

For further configuration, please refer to the Argilla documentation.

Usage


from litellm import completion

# add env vars
os.environ["ARGILLA_API_KEY"]="argilla.apikey"
os.environ["ARGILLA_BASE_URL"]="http://localhost:6900"
os.environ["ARGILLA_DATASET_NAME"]="my_first_dataset"   
os.environ["OPENAI_API_KEY"]="sk-proj-..."

litellm.callbacks = ["argilla"]

# add argilla transformation object
litellm.argilla_transformation_object = {
    "user_input": "messages", # 👈 key= argilla field, value = either message (argilla.ChatField) | response (argilla.TextField)
    "llm_output": "response"
}

## LLM CALL ## 
response = completion(
    model="gpt-3.5-turbo",
    messages=[{"role": "user", "content": "Hello, how are you?"}],
)
litellm_settings:
  callbacks: ["argilla"]
  argilla_transformation_object:
    user_input: "messages" # 👈 key= argilla field, value = either message (argilla.ChatField) | response (argilla.TextField)
    llm_output: "response"

Example Output

Add sampling rate to Argilla calls

To just log a sample of calls to argilla, add ARGILLA_SAMPLING_RATE to your env vars.

ARGILLA_SAMPLING_RATE=0.1 # log 10% of calls to argilla
