⚡ Test suite for LLM prompts before pushing them to PROD ⚡

Our work is inspired by this paper Demystifying Prompts in Language Models via Perplexity Estimation which showed that

Over a wide range of tasks, we show that the lower the perplexity of the prompt (i.e. closer to zero) is, the better the prompt is able to perform the task.

Getting Started

To get started with betterprompt, you will need to first install the library by running the following command:

pip install betterprompt

Once installed, you can import it into your python project by running the following:

import betterprompt

Using betterprompt

betterprompt currently provides 1 main functions - calculate_perplexity.

The calculate_perplexity function takes in a prompt as a string and calculates the perplexity of the text using the OpenAI GPT-3 API. It returns the perplexity as a float.

Example

Here is an example of how to use Betterprompt to calculate the perplexity of a given prompt:

import betterprompt

prompt = "This is a sample prompt"

perplexity = betterprompt.calculate_perplexity(prompt)

print(perplexity) # Outputs the perplexity of the text

Version

The current version of Betterprompt is 0.4.0.
