Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

✨ New Features

📦 Package @promptbook/utils

To install this package, run:

# Install entire promptbook ecosystem
npm i ptbk

# Install just this package to save space
npm install @promptbook/utils

Utility functions used in the library but also useful for individual use in preprocessing and postprocessing LLM inputs and outputs

Here is a overview of the functions which are exported from the @promptbook/utils package and can be used in your own projects:

Postprocessing

Sometimes you need to postprocess the output of the LLM model, every postprocessing function that is available through POSTPROCESS command in promptbook is exported from @promptbook/utils. You can use:

Very often you will use unwrapResult, which is used to extract the result you need from output with some additional information:

import { unwrapResult } from '@promptbook/utils';

unwrapResult('Best greeting for the user is "Hi Pavol!"'); // 'Hi Pavol!'

Templating

There is a function replaceParameters which is used to replace the parameters in given template optimized to LLM prompt templates.

import { replaceParameters } from '@promptbook/utils';

replaceParameters('Hello, {name}!', { name: 'world' }); // 'Hello, world!'

And also multiline templates with blockquotes

import { replaceParameters, spaceTrim } from '@promptbook/utils';

replaceParameters(
    spaceTrim(`
        Hello, {name}!

        > {answer}
    `),
    {
        name: 'world',
        answer: spaceTrim(`
            I'm fine,
            thank you!

            And you?
        `),
    },
);

// Hello, world!
//
// > I'm fine,
// > thank you!
// >
// > And you?

Counting

Theese functions are usefull to count stats about the input/output in human-like terms not tokens and bytes, you can use countCharacters, countLines, countPages, countParagraphs, countSentences, countWords

import { countWords } from '@promptbook/utils';

console.log(countWords('Hello, world!')); // 2

Splitting

Splitting functions are similar to counting but they return the splitted parts of the input/output, you can use splitIntoCharacters, splitIntoLines, splitIntoPages, splitIntoParagraphs, splitIntoSentences, splitIntoWords

import { splitIntoWords } from '@promptbook/utils';

console.log(splitIntoWords('Hello, world!')); // ['Hello', 'world']

Normalization

Normalization functions are used to put the string into a normalized form, you can use kebab-case PascalCase SCREAMING_CASE snake_case kebab-case

import { normalizeTo } from '@promptbook/utils';

console.log(normalizeTo['kebab-case']('Hello, world!')); // 'hello-world'
  • There are more normalization functions like capitalize, decapitalize, removeDiacritics,...
  • Theese can be also used as postprocessing functions in the POSTPROCESS command in promptbook

Misc

See also the documentation for all the functions in the @promptbook/utils package, every function is documented by jsdoc, typed by typescript and tested by jest.

assertsExecutionSuccessful, checkExpectations, executionReportJsonToString, isPassingExpectations, isValidJsonString, parseNumber


Rest of the documentation is common for entire promptbook ecosystem:

🤍 The Promptbook Whitepaper

If you have a simple, single prompt for ChatGPT, GPT-4, Anthropic Claude, Google Gemini, Llama 3, or whatever, it doesn't matter how you integrate it. Whether it's calling a REST API directly, using the SDK, hardcoding the prompt into the source code, or importing a text file, the process remains the same.

But often you will struggle with the limitations of LLMs, such as hallucinations, off-topic responses, poor quality output, language and prompt drift, word repetition repetition repetition repetition or misuse, lack of context, or just plain w𝒆𝐢rd resp0nses. When this happens, you generally have three options:

  1. Fine-tune the model to your specifications or even train your own.
  2. Prompt-engineer the prompt to the best shape you can achieve.
  3. Orchestrate multiple prompts in a pipeline to get the best result.

In all of these situations, but especially in 3., the ✨ Promptbook can make your life waaaaaaaaaay easier.

  • Separates concerns between prompt-engineer and programmer, between code files and prompt files, and between prompts and their execution logic. For this purpose, it introduces a new language called the 💙 Book.
  • Book allows you to focus on the business logic without having to write code or deal with the technicalities of LLMs.
  • Forget about low-level details like choosing the right model, tokens, context size, temperature, top-k, top-p, or kernel sampling. Just write your intent and persona who should be responsible for the task and let the library do the rest.
  • We have built-in orchestration of pipeline execution and many tools to make the process easier, more reliable, and more efficient, such as caching, compilation+preparation, just-in-time fine-tuning, expectation-aware generation, agent adversary expectations, and more.
  • Sometimes even the best prompts with the best framework like Promptbook :) can't avoid the problems. In this case, the library has built-in anomaly detection and logging to help you find and fix the problems.
  • Versioning is build in. You can test multiple A/B versions of pipelines and see which one works best.
  • Promptbook is designed to use RAG (Retrieval-Augmented Generation) and other advanced techniques to bring the context of your business to generic LLM. You can use knowledge to improve the quality of the output.

💜 The Promptbook Project

Promptbook project is ecosystem of multiple projects and tools, following is a list of most important pieces of the project:

💙 Book language (for prompt-engineer)

💙 The blueprint of book language

Following is the documentation and blueprint of the Book language.

Example

# 🌟 My first Book

-   PERSONA Jane, marketing specialist with prior experience in writing articles about technology and artificial intelligence
-   KNOWLEDGE https://ptbk.io
-   KNOWLEDGE ./promptbook.pdf
-   EXPECT MIN 1 Sentence
-   EXPECT MAX 1 Paragraph

> Write an article about the future of artificial intelligence in the next 10 years and how metalanguages will change the way AI is used in the world.
> Look specifically at the impact of Promptbook on the AI industry.

Goals and principles of book language

File is designed to be easy to read and write. It is strict subset of markdown. It is designed to be understandable by both humans and machines and without specific knowledge of the language.

It has file with .book.md or .book extension with UTF-8 non BOM encoding.

As it is source code, it can leverage all the features of version control systems like git and does not suffer from the problems of binary formats, proprietary formats, or no-code solutions.

But unlike programming languages, it is designed to be understandable by non-programmers and non-technical people.

Structure

Book is divided into sections. Each section starts with heading. The language itself is not sensitive to the type of heading (h1, h2, h3, ...) but it is recommended to use h1 for header section and h2 for other sections.

Header

Header is the first section of the book. It contains metadata about the pipeline. It is recommended to use h1 heading for header section but it is not required.

📚 Dictionary

📚 Dictionary

The following glossary is used to clarify certain concepts:

General LLM / AI terms

  • Prompt drift is a phenomenon where the AI model starts to generate outputs that are not aligned with the original prompt. This can happen due to the model's training data, the prompt's wording, or the model's architecture.
  • Pipeline, workflow or chain is a sequence of tasks that are executed in a specific order. In the context of AI, a pipeline can refer to a sequence of AI models that are used to process data.
  • Fine-tuning is a process where a pre-trained AI model is further trained on a specific dataset to improve its performance on a specific task.
  • Zero-shot learning is a machine learning paradigm where a model is trained to perform a task without any labeled examples. Instead, the model is provided with a description of the task and is expected to generate the correct output.
  • Few-shot learning is a machine learning paradigm where a model is trained to perform a task with only a few labeled examples. This is in contrast to traditional machine learning, where models are trained on large datasets.
  • Meta-learning is a machine learning paradigm where a model is trained on a variety of tasks and is able to learn new tasks with minimal additional training. This is achieved by learning a set of meta-parameters that can be quickly adapted to new tasks.
  • Retrieval-augmented generation is a machine learning paradigm where a model generates text by retrieving relevant information from a large database of text. This approach combines the benefits of generative models and retrieval models.
  • Longtail refers to non-common or rare events, items, or entities that are not well-represented in the training data of machine learning models. Longtail items are often challenging for models to predict accurately.
