No project description provided

Overview

This package provides a vectorized interface for the OpenAI API, enabling you to process multiple inputs with a single API call instead of sending requests one by one. This approach helps reduce latency and simplifies your code.

Additionally, it integrates effortlessly with Pandas DataFrames and Apache Spark UDFs, making it easy to incorporate into your data processing pipelines.

Features

• Vectorized API requests for processing multiple inputs at once.
• Seamless integration with Pandas DataFrames.
• A UDF builder for Apache Spark.
• Compatibility with multiple OpenAI clients, including Azure OpenAI.

Requirements

• Python 3.10 or higher

Installation

Install the package with:

pip install openaivec

If you want to uninstall the package, you can do so with:

pip uninstall openaivec

Basic Usage

import os
from openai import OpenAI
from openaivec import VectorizedOpenAI


# Initialize the vectorized client with your system message and parameters
client = VectorizedOpenAI(
    client=OpenAI(...),
    temperature=0.0,
    top_p=1.0,
    model_name="<your-model-name>",
    system_message="Please answer only with 'xx family' and do not output anything else."
)

result = client.predict(["panda", "rabbit", "koala"])
print(result)  # Expected output: ['bear family', 'rabbit family', 'koala family']

Using with Pandas DataFrame

import pandas as pd

df = pd.DataFrame({"name": ["panda", "rabbit", "koala"]})

df.assign(
    kind=lambda df: client.predict(df.name)
)

Example output:

name	kind
panda	bear family
rabbit	rabbit family
koala	koala family

Using with Apache Spark UDF

Below is an example showing how to create UDFs for Apache Spark using the provided UDFBuilder. This configuration is intended for use with Azure OpenAI.

from openaivec.spark import UDFBuilder

udf = UDFBuilder(
    api_key="<your-api-key>",
    api_version="2024-10-21",
    endpoint="https://<your_resource_name>.openai.azure.com",
    model_name="<your_deployment_name>"
)

# Register UDFs (e.g., to extract flavor or product type from product names)
spark.udf.register("parse_taste", udf.completion("""
- Extract flavor-related information from the product name. Return only the concise flavor name with no extra text.
- Minimize unnecessary adjectives related to the flavor.
    - Example:
        - Hokkaido Milk → Milk
        - Uji Matcha → Matcha
"""))

# Register UDFs (e.g., to extract product type from product names)
spark.udf.register("parse_product", udf.completion("""
- Extract the type of food from the product name. Return only the food category with no extra text.
- Example output:
    - Smoothie
    - Milk Tea
    - Protein Bar
"""))

You can then use the UDFs in your Spark SQL queries as follows:

SELECT id,
       product_name,
       parse_taste(product_name)   AS taste,
       parse_product(product_name) AS product
FROM product_names;

Example Output:

id	product_name	taste	product
4414732714624	Cafe Mocha Smoothie (Trial Size)	Mocha	Smoothie
4200162318339	Dark Chocolate Tea (New Product)	Chocolate	Tea
4920122084098	Cafe Mocha Protein Bar (Trial Size)	Mocha	Protein Bar
4468864478874	Dark Chocolate Smoothie (On Sale)	Chocolate	Smoothie
4036242144725	Uji Matcha Tea (New Product)	Matcha	Tea
4847798245741	Hokkaido Milk Tea (Trial Size)	Milk	Milk Tea
4449574211957	Dark Chocolate Smoothie (Trial Size)	Chocolate	Smoothie
4127044426148	Fruit Mix Tea (Trial Size)	Fruit	Tea
...	...	...	...

Building Prompts

Building prompt is a crucial step in using LLMs. In particular, providing a few examples in a prompt can significantly improve an LLM’s performance, a technique known as "few-shot learning." Typically, a few-shot prompt consists of a purpose, cautions, and examples.

FewShotPromptBuilder is a class that helps you build a few-shot learning prompt with simple interface.

Basic Usage

FewShotPromptBuilder requires simply a purpose, cautions, and examples, and build method will return rendered prompt with XML format.

Here is an example:

from openaivec.prompt import FewShotPromptBuilder

prompt: str = (
    FewShotPromptBuilder()
    .purpose("Return the smallest category that includes the given word")
    .caution("Never use proper nouns as categories")
    .example("Apple", "Fruit")
    .example("Car", "Vehicle")
    .example("Tokyo", "City")
    .example("Keiichi Sogabe", "Musician")
    .example("America", "Country")
    .build()
)
print(prompt)

The output will be:

<Prompt>
    <Purpose>Return the smallest category that includes the given word</Purpose>
    <Cautions>
        <Caution>Never use proper nouns as categories</Caution>
    </Cautions>
    <Examples>
        <Example>
            <Source>Apple</Source>
            <Result>Fruit</Result>
        </Example>
        <Example>
            <Source>Car</Source>
            <Result>Vehicle</Result>
        </Example>
        <Example>
            <Source>Tokyo</Source>
            <Result>City</Result>
        </Example>
        <Example>
            <Source>Keiichi Sogabe</Source>
            <Result>Musician</Result>
        </Example>
        <Example>
            <Source>America</Source>
            <Result>Country</Result>
        </Example>
    </Examples>
</Prompt>

Improve with openai

For most analysts, it can be challenging to write a prompt entirely free of contradictions, ambiguities, or redundancies. FewShotPromptBuilder provides a method improve to help you improve the prompt with OpenAI's API.

improve method will try to eliminate contradictions, ambiguities, and redundancies in the prompt with OpenAI's API, and iterate the process up to max_iter times.

from openai import OpenAI
from openaivec.prompt import FewShotPromptBuilder

client = OpenAI(...)
model_name = "<your-model-name>"
improved_prompt: str = (
    FewShotPromptBuilder()
    .purpose("Return the smallest category that includes the given word")
    .caution("Never use proper nouns as categories")
    # Examples has contradictions, ambiguities, or redundancies
    .example("Apple", "Fruit")
    .example("Apple", "Technology")
    .example("Apple", "Company")
    .example("Apple", "Color")
    .example("Apple", "Animal")
    # improve the prompt with OpenAI's API, max_iter is number of iterations to improve the prompt.
    .improve(client, model_name, max_iter=5)
    .build()
)
print(improved_prompt)

Then we will get the improved prompt with extra examples, improved purpose, and cautions:

<Prompt>
    <Purpose>Classify a given word into its most relevant category by considering its context and potential meanings.
        The input is a word accompanied by context, and the output is the appropriate category based on that context.
        This is useful for disambiguating words with multiple meanings, ensuring accurate understanding and
        categorization.
    </Purpose>
    <Cautions>
        <Caution>Ensure the context of the word is clear to avoid incorrect categorization.</Caution>
        <Caution>Be aware of words with multiple meanings and provide the most relevant category.</Caution>
        <Caution>Consider the possibility of new or uncommon contexts that may not fit traditional categories.</Caution>
    </Cautions>
    <Examples>
        <Example>
            <Source>Apple (as a fruit)</Source>
            <Result>Fruit</Result>
