Use ai.generate_response with pandas

The ai.generate_response function creates custom text from your prompt and row data.

Note

Overview

The ai.generate_response function extends pandas Series and pandas DataFrame. For DataFrame calls, use a literal prompt to include all columns or a template prompt to include only columns in braces, such as {product}.

The function returns a pandas Series that contains custom text responses for each row of input. The text responses can be stored in a new DataFrame column.

Tip

Learn how to craft more effective prompts to get higher-quality responses by following the OpenAI prompt engineering guide.

Syntax

df["response"] = df.ai.generate_response(
    prompt="Instructions for a custom response based on all column values",
)

Parameters

Name Description
prompt
Required
A string that contains prompt instructions to apply to input text values for custom responses.
is_prompt_template
Optional
A Boolean that indicates whether the prompt is a format string. When True, the function uses only columns named in braces. When False, it uses all columns as row context.
response_format
Optional
None, a dictionary, a string, or a class based on Pydantic's BaseModel that specifies the expected structure of the model's response. See Response format options.

Returns

The function returns a pandas Series that contains custom text responses for each input row.

Response format options

Use response_format to control response structure. It corresponds to OpenAI Structured Outputs.

Format Description
None (default) Let the LLM decide response format based on the instructions and input data, which can vary per row. Responses can be plain text or JSON dict with varying fields.
"text" or {"type": "text"} Forces plain text responses for all rows.
"json_object" or {"type": "json_object"} Returns a JSON dictionary in text form where the LLM decides the fields. Requires the word "json" in your prompt.
{"type": "json_schema", ...} Returns a JSON dictionary that conforms to your custom JSON Schema. Provides precise control over response structure.
Class based on Pydantic's BaseModel Returns a JSON string that conforms to your Pydantic model definition. Pydantic is a dependency of the OpenAI package. Under the hood, the Pydantic BaseModel is automatically converted to a JSON schema and functions equivalently to the json_schema option.

Note

The json_schema and Pydantic BaseModel options are equivalent. Use Pydantic when you want Python type hints and validation.

Examples

# This code uses AI. Always review output for mistakes.

df = pd.DataFrame([
        ("Scarves"),
        ("Snow pants"),
        ("Ski goggles")
    ], columns=["product"])

df["response"] = df.ai.generate_response("Write a short, punchy email subject line for a winter sale.")
display(df)

Output:

Screenshot showing a data frame with columns 'product' and 'response'. The 'response' column contains a punchy subject line for the product.

Response format example

The following example requests plain text, a JSON object, a custom JSON Schema, and a Pydantic model.

# This code uses AI. Always review output for mistakes.

df = pd.DataFrame([
        ("Alex Rivera is a 24-year-old soccer midfielder from Barcelona who scored 12 goals last season."),
        ("Jordan Smith, a 29-year-old basketball guard from Chicago, averaged 22 points per game."),
        ("William O'Connor is a 22-year-old tennis player from Dublin who won 3 ATP titles this year.")
    ], columns=["bio"])

# response_format : text
df["card_text"] = df.ai.generate_response(
    "Create a player card with the player's details and a motivational quote", 
    response_format={"type": "text"},
)

# response_format : json object
df["card_json_object"] = df.ai.generate_response(
    "Create a player card with the player's details and a motivational quote in JSON", 
    response_format={"type": "json_object"},  # Requires word "json" in the prompt
)

# response_format : specified json schema
df["card_json_schema"] = df.ai.generate_response(
    "Create a player card with the player's details and a motivational quote", 
    response_format={
        "type": "json_schema",
            "json_schema": {
            "name": "player_card_schema",
            "strict": True,
            "schema": {
                "type": "object",
                "properties": {
                    "name": {"type": "string"},
                    "age": {"type": "integer"},
                    "sport": {"type": "string"},
                    "position": {"type": "string"},
                    "hometown": {"type": "string"},
                    "stats": {"type": "string", "description": "Key performance metrics or achievements"},
                    "motivational_quote": {"type": "string"}
                },
                "required": ["name", "age", "sport", "position", "hometown", "stats", "motivational_quote"],
                "additionalProperties": False,
            },
        },
    },
)

# Pydantic is a dependency of the OpenAI package, so it's available when openai is installed.
# You can also install Pydantic via `%pip install pydantic` if it's not already present.
from pydantic import BaseModel, Field

class PlayerCardSchema(BaseModel):
    name: str
    age: int
    sport: str
    position: str
    hometown: str
    stats: str = Field(description="Key performance metrics or achievements")
    motivational_quote: str

# response_format : pydantic BaseModel
df["card_pydantic"] = df.ai.generate_response(
    "Create a player card with the player's details and a motivational quote",
    response_format=PlayerCardSchema,
)

display(df)

Output:

Screenshot showing a data frame with a 'bio' column, and a new column for each specified format, with its corresponding formatted output.

Multimodal input

To generate responses from images, PDFs, or text files, mark file path columns as path inputs. For setup, see Use multimodal input with AI Functions.

For Series-level calls, set column_type="path":

# This code uses AI. Always review output for mistakes.

animal_urls = [
    "<image-url-golden-retriever>",  # Replace with URL to an image of a golden retriever
    "<image-url-giant-panda>",  # Replace with URL to an image of a giant panda
    "<image-url-bald-eagle>",  # Replace with URL to an image of a bald eagle
]
animal_df = pd.DataFrame({"file_path": animal_urls})

animal_df["animal_name"] = animal_df["file_path"].ai.generate_response(
    prompt="What type of animal is in this image? Give me only the animal's common name.",
    column_type="path",
)
display(animal_df)

For DataFrame-level calls, use column_type_dict to specify which columns contain file paths:

# This code uses AI. Always review output for mistakes.

animal_df["description"] = animal_df.ai.generate_response(
    prompt="Describe this animal's natural habitat and one interesting fact about it.",
    column_type_dict={"file_path": "path"},
)
display(animal_df)
