Data Designer SDK

If you prefer not to use YAML, you can use the Gretel SDK to define your Data Designer workflow, here is a simple example.

Step 1: Define your Model Suite and System Prompt

from gretel_client.navigator import DataDesigner

session_kwargs = {
    "api_key": "<YOUR_API_KEY>",
    "endpoint": "https://api.gretel.cloud",
}

model_suite = 'apache-2.0'

special_system_instructions = """
    You are an expert conversation designer and domain specialist. Your job is to
    produce realistic user-assistant dialogues for fine-tuning a model. Always ensure:
    - Responses are factually correct and contextually appropriate.
    - Communication is clear, helpful, and matches the complexity level.
    - Avoid disallowed content and toxicity.
    - After the two-turn conversation, provide a single toxicity assessment for the user's messages in the entire conversation.
 """

Step 2: Add your Seed Columns

data_designer = DataDesigner(
    model_suite=model_suite,
    special_system_instructions=special_system_instructions,
    **session_kwargs
)

data_designer.add_categorical_seed_column(
    name="event_type",
    values=["Login", "Logout", "PageView"]
)


data_designer.add_categorical_seed_column(
    name="user_type",
    values=["Anonymous", "Registered"]
)

data_designer.add_categorical_seed_column(
    name="device_type",
    values=["Mobile", "Desktop", "Tablet"]
)

data_designer.add_categorical_seed_column(
    name="action_status",
    values=["Success", "Failure"]
)

Step 3: Add your Data Columns

data_designer.add_generated_data_column(
    name="timestamp",
    generation_prompt=(
        "Generate a realistic timestamp for an {event_type} event within the last 24 hours." \
        "Format: YYYY-MM-DD HH:MM:SS" 
    )
)

data_designer.add_generated_data_column(
    name="event_details",
    generation_prompt=(
        "Create event details for a {event_type} by a {user_type} user on {device_type} with status {action_status}." \
        "Include basic information like device ID and session duration if applicable." 
    )
)

Generate Data

Once you have a define DataDesignerobject, you can generate your dataset.

Preview Data

You can generate a quick preview of your dataset, assess the data generated, and adjust your config if needed.

preview = data_designer.generate_dataset_preview()

Submit a Batch Job

Once you are happy with your configuration, you can submit a batch job to generate as many records as you want!
