Promptuner

Turning small task descriptions into mega prompts automatically 🪄✨

🚀 promptuner is an open-source library that converts simple task descriptions into detailed, high-quality prompts for any large language model. With promptuner, even small models can achieve remarkable results by extracting perfect JSON, making function calls, creating structured outputs, and performing complex reasoning and analytical tasks.

Features

• Automagically Convert Task Descriptions: Turn small task descriptions into professional, detailed prompts effortlessly.
• Enhanced Performance: Get the most out of your models, even small ones, with fine-tuned prompts.
• Supports Complex Tasks: Generate prompts for tasks requiring reasoning, chain of thoughts, and other analytical methods.
• Execute Prompts: Ability to execute the generated prompts for you.

Getting Started

Installation

To install promptuner, use pip:

pip install git+https://github.com/unclecode/promptuner.git

Usage

You may try this Colab

Here's a basic example of how to use promptuner. First make sure to set your Anthropic Api Key in the environment variable ANTHROPIC_API_KEY.

export ANTHROPIC_API_KEY=YOUR_ANTHROPIC_API_KEY

I use Claude only for generating the prompt, which I found better than other models, however you may try other models as well. Specially the recent ones like Llama3.1-70b or Llama3.1-405b.

1. Create the Prompt

from promptuner import Prompt
from promptuner.decorators import *
 
# Define the task
TASK = """Analyze the given email content and perform the following:
1. Classify the email into one of the provided class labels.
2. Score the email's importance on a scale of 1 to 10.
3. Provide a one-sentence summary of the email.
4. Extract the sender's email address.
Return the results in a JSON format."""

# Initialize a new Prompt
prompt = Prompt(TASK, variables=["EMAIL_CONTENT", "CLASS_LABELS"])
prompt.apply_decorator([
    Scratchpad(repeat=1),
    OutputExamples(repeat=1),
    ResultWrapper(repeat=1, tag="analysis"),
    JsonResponse()
])

# Train the prompt
prompt.train()

# Print the generated prompt template
print("Generated Prompt Template:")
print(prompt.content)
prompt.save("email_analysis_prompt.json")

2. Use the Prompt You may simply use the generated prompt, replace the generate variables with the actual values and pass the prompt to your favorite model. Another way is to use the promptuner library to execute the prompt for you.

# Sample email content
EMAIL_CONTENT = """
From: [email protected]
Subject: Urgent: Project Deadline Extension Request

Dear Team,

I hope this email finds you well. I'm writing to request an extension for the upcoming project deadline. Due to unforeseen circumstances, including a critical team member's illness and some technical challenges we've encountered, we're slightly behind schedule.

We've made significant progress, but we need an additional week to ensure we deliver a high-quality product. I believe this extension will allow us to address all remaining issues and exceed your expectations.

Please let me know if you need any further information or if you'd like to discuss this matter in more detail. I appreciate your understanding and look forward to your response.

Best regards,
John Doe
Project Manager

prompt = Prompt.load("email_analysis_prompt.json")
# Define class labels
CLASS_LABELS = "Work-related, Personal, Spam, Urgent, Newsletter, Other"

# First Method: Use the generated prompt directly
import re
new_prompt = prompt.content.replace("{{EMAIL_CONTENT}}", EMAIL_CONTENT)
new_prompt = prompt.content.replace("{{CLASS_LABELS}}", CLASS_LABELS)
from openai import OpenAI
client = OpenAI()

completion = client.chat.completions.create(
  model="gpt-4o",
  messages=[
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": new_prompt}
  ]
)

answer = completion.choices[0].message
tag = "analysis"
pattern = f"<{tag}>(.*?)</{tag}>"
match = re.search(pattern, answer, re.DOTALL)
if match:
    result = match.group(1).strip()
print("\nEmail Analysis Results:")
print(result)

# Second Method: Use the promptuner library to execute the prompt
response = prompt(
    variable_values={
        "EMAIL_CONTENT": EMAIL_CONTENT,
        "CLASS_LABELS": CLASS_LABELS
    },

    # model_name="ollama/llama3"
    # model_name="ollama/qwen2:0.5b"
    # model_name="ollama/qwen2:1.5b"
)

print("\nEmail Analysis Results:")
print(response['answer'])

print("\nTags:")
for tag, content in response['tags'].items():
    if tag != "analysis":
        print(f"<{tag}>\n{content}\n</{tag}>")
