Overview of gpt-prompt-engineer

What is gpt-prompt-engineer?

gpt-prompt-engineer is an open-source tool designed to automate the process of prompt engineering for large language models (LLMs) like GPT-4, GPT-3.5-Turbo, and Claude 3. It helps users discover optimal prompts by generating, testing, and ranking multiple prompts based on user-defined test cases.

How does gpt-prompt-engineer work?

  1. Prompt Generation: The tool uses LLMs to generate a diverse range of prompts based on a provided use-case description and associated test cases.
  2. Prompt Testing: Each generated prompt is tested against the provided test cases to evaluate its performance.
  3. ELO Rating System: An ELO rating system is employed to rank the prompts based on their performance. Each prompt starts with an initial ELO rating, and the ratings are adjusted based on the prompt's performance against the test cases. This enables users to easily identify the most effective prompts.

Key Features of gpt-prompt-engineer

  • Automated Prompt Generation: Automatically generates a multitude of potential prompts based on a given use-case and test cases.
  • Prompt Testing and Ranking: Systematically tests each prompt against the test cases and ranks them using an ELO rating system to identify the most effective ones.
  • Claude 3 Opus Support: A specialized version takes full advantage of Anthropic's Claude 3 Opus model, allowing for automated test case generation and multiple input variables.
  • Claude 3 Opus → Haiku Conversion: This feature enables users to leverage Claude 3 Opus to define the latent space and Claude 3 Haiku for efficient output generation, reducing latency and cost.
  • Classification Version: Designed for classification tasks, this version evaluates the correctness of a test case by matching it to the expected output ('true' or 'false') and provides a table with scores for each prompt.
  • Weights & Biases Logging: Optional logging to Weights & Biases for tracking configurations, system and user prompts, test cases, and final ELO ratings.
  • Portkey Integration: Offers optional integration with Portkey for logging and tracing prompt chains and their responses.

How to use gpt-prompt-engineer?

  1. Setup: Open the desired notebook in Google Colab or a local Jupyter notebook. Choose between the standard version, the classification version, or the Claude 3 version depending on your use case.
  2. API Key Configuration: Add your OpenAI API key or Anthropic API key to the designated line in the notebook.
  3. Define Use-Case and Test Cases: For the GPT-4 version, define your use-case and test cases. The use-case is a description of what you want the AI to do, and test cases are specific prompts that you would like the AI to respond to.
  4. Configure Input Variables (for Claude 3 version): Define input variables in addition to the use-case description, specifying the variable name and its description.
  5. Generate Optimal Prompts: Call the generate_optimal_prompt function with the use-case description, test cases, and the desired number of prompts to generate.
  6. Evaluate Results: The final ELO ratings will be printed in a table, sorted in descending order. The higher the rating, the better the prompt. For the classification version, the scores for each prompt will be printed in a table.

Who is gpt-prompt-engineer for?

gpt-prompt-engineer is ideal for:

  • AI developers and researchers seeking to optimize prompts for LLMs.
  • Businesses looking to improve the performance of AI-powered applications.
  • Individuals interested in exploring prompt engineering techniques.
  • Anyone looking to reduce the cost and latency of LLM-based applications.

Use Cases:

  • Automating the generation of landing page headlines.
  • Creating personalized email responses.
  • Optimizing prompts for content generation.
  • Building cost-effective AI systems using Claude 3 Opus and Haiku.

Why choose gpt-prompt-engineer?

  • Time Savings: Automates the prompt engineering process, saving significant time and effort.
  • Improved Performance: Helps discover optimal prompts that lead to improved performance of LLMs.
  • Cost Reduction: Enables the creation of cost-effective AI systems by leveraging efficient models like Claude 3 Haiku.
  • Flexibility: Supports various LLMs and use cases, including classification tasks.
