prompt-templates 0.0.12

A library for working with prompt templates locally or on the Hugging Face Hub.

Prompt Templates

Prompt templates have become key artifacts for researchers and practitioners working with AI. There is, however, no standardized way of sharing prompt templates. Prompts and prompt templates are shared on the Hugging Face Hub in .txt files, in HF datasets, as strings in model cards, or on GitHub as python strings embedded in scripts, in JSON and YAML files, or in Jinja2 files.

Objectives and non-objectives of this library

Objectives

• Provide functionality for working with prompt templates locally and sharing them on the Hugging Face Hub.
• Propose a prompt template standard through .yaml and .json files that enables modular development of complex LLM systems and is interoperable with other libraries

Non-Objective

• Compete with full-featured prompting libraries like LangChain, ell, etc. The objective is, instead, a simple solution for working with prompt templates locally or on the HF Hub, which is interoperable with other libraries and which the community can build upon.

Documentation

A discussion of the standard prompt format, usage examples, the API reference etc. are available in the docs.

Quick start

Let's use this closed_system_prompts repo of official prompts from OpenAI and Anthropic. These prompt templates have either been leaked or were shared by these LLM providers, but were originally in a non-machine-readable, non-standardized format.

1. Install the library:

pip install prompt-templates

2. List available prompts in a HF Hub repository.

from prompt_templates import list_prompt_templates
files = list_prompt_templates("MoritzLaurer/closed_system_prompts")
print(files)
# ['claude-3-5-artifacts-leak-210624.yaml', 'claude-3-5-sonnet-text-090924.yaml', 'claude-3-5-sonnet-text-image-090924.yaml', 'openai-metaprompt-audio.yaml', 'openai-metaprompt-text.yaml']

3. Download and inspect a prompt template

from prompt_templates import PromptTemplateLoader
prompt_template = PromptTemplateLoader.from_hub(
    repo_id="MoritzLaurer/closed_system_prompts",
    filename="claude-3-5-artifacts-leak-210624.yaml"
)
# Inspect template
print(prompt_template.template)
#[{'role': 'system',
#  'content': '<artifacts_info>\nThe assistant can create and reference artifacts ...'},
# {'role': 'user', 'content': '{{user_message}}'}]
# Check required template variables
print(prompt_template.template_variables)
# ['current_date', 'user_message']
print(prompt_template.metadata)
# {'source': 'https://gist.github.com/dedlim/6bf6d81f77c19e20cd40594aa09e3ecd'}

4. Populate the template with variables

By default, the populated prompt is returned in the OpenAI messages format, which is compatible with most open-source LLM clients.

messages = prompt_template.populate_template(
    user_message="Create a tic-tac-toe game for me in Python",
    current_date="Wednesday, 11 December 2024"
)
print(messages)
# PopulatedPrompt([{'role': 'system', 'content': '<artifacts_info>\nThe assistant can create and reference artifacts during conversations. Artifacts are ...'}, {'role': 'user', 'content': 'Create a tic-tac-toe game for me in Python'}])

5. Use the populated template with any LLM client

#!pip install openai
from openai import OpenAI
import os
client = OpenAI(api_key=os.environ.get("OPENAI_API_KEY"))
response = client.chat.completions.create(
    model="gpt-4o-mini",
    messages=messages
)
print(response.choices[0].message.content[:100], "...")
# Here's a simple text-based Tic-Tac-Toe game in Python. This code allows two players to take turns pl ...

from huggingface_hub import InferenceClient
client = InferenceClient(api_key=os.environ.get("HF_TOKEN"))
response = client.chat.completions.create(
    model="meta-llama/Llama-3.3-70B-Instruct", 
    messages=messages.to_dict(),
    max_tokens=500
)
print(response.choices[0].message.content[:100], "...")
# <antThinking>Creating a tic-tac-toe game in Python is a good candidate for an artifact. It's a self- ...

If you use an LLM client that expects a format different to the OpenAI messages standard, you can easily reformat the prompt for this client. For example with Anthropic:

#! pip install anthropic
from anthropic import Anthropic

messages_anthropic = messages.format_for_client(client="anthropic")

client = Anthropic(api_key=os.environ.get("ANTHROPIC_API_KEY"))
response = client.messages.create(
    model="claude-3-sonnet-20240229",
    system=messages_anthropic["system"],
    messages=messages_anthropic["messages"],
    max_tokens=1000
)
print(response.content[0].text[:100], "...")
# Sure, I can create a tic-tac-toe game for you in Python. Here's a simple implementation: ...

Or with the Google Gen AI SDK for Gemini 2.0

#!pip install google-genai
from google import genai
from google.genai import types

messages_gemini = messages.format_for_client(client="gemini")

client = genai.Client(api_key=os.environ.get("GEMINI_API_KEY"))

response = client.models.generate_content(
    model='gemini-2.0-flash-exp',
    contents=messages_gemini["contents"],
    config=types.GenerateContentConfig(
        system_instruction=messages_gemini["system_instruction"],
    )
)
print(response.text[:100], "...")

6. Create your own prompt templates

from prompt_templates import ChatPromptTemplate
messages_template = [
    {"role": "system", "content": "You are a coding assistant who explains concepts clearly and provides short examples."},
    {"role": "user", "content": "Explain what {{concept}} is in {{programming_language}}."}
]
template_variables = ["concept", "programming_language"]
metadata = {
    "name": "Code Teacher",
    "description": "A simple chat prompt for explaining programming concepts with examples",
    "tags": ["programming", "education"],
    "version": "0.0.1",
    "author": "Guido van Bossum"
}
prompt_template = ChatPromptTemplate(
    template=messages_template,
    template_variables=template_variables,
    metadata=metadata,
)

print(prompt_template)
# ChatPromptTemplate(template=[{'role': 'system', 'content': 'You are a coding a..., template_variables=['concept', 'programming_language'], metadata={'name': 'Code Teacher', 'description': 'A simple ..., client_parameters={}, custom_data={}, populator_type='double_brace', populator=<prompt_templates.prompt_templates.DoubleBracePopu...)

7. Store or share your prompt templates

You can then store your prompt template locally or share it on the HF Hub.

# save locally
prompt_template.save_to_local("./tests/test_data/code_teacher_test.yaml")
# or save it on the HF Hub
prompt_template.save_to_hub(repo_id="MoritzLaurer/example_prompts_test", filename="code_teacher_test.yaml", create_repo=True)
# CommitInfo(commit_url='https://huggingface.co/MoritzLaurer/example_prompts_test/commit/4cefd2c94f684f9bf419382f96b36692cd175e84', commit_message='Upload prompt template code_teacher_test.yaml', commit_description='', oid='4cefd2c94f684f9bf419382f96b36692cd175e84', pr_url=None, repo_url=RepoUrl('https://huggingface.co/MoritzLaurer/example_prompts_test', endpoint='https://huggingface.co', repo_type='model', repo_id='MoritzLaurer/example_prompts_test'), pr_revision=None, pr_num=None)
