๐Ÿค 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 w๐’†๐ขrd 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 โœจ 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 ๐Ÿ’™ 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.

๐Ÿ’™ Book language (for prompt-engineer)

Promptbook pipelines are written in markdown-like language called Book. It is designed to be understandable by non-programmers and non-technical people.

๐Ÿ“ฆ Packages (for developers)

This library is divided into several packages, all are published from single monorepo. You can install all of them at once:

npm i ptbk

Or you can install them separately:

๐Ÿ”Œ Usage in Typescript / Javascript

โž•โž– When to use Promptbook?

โž• When to use

  • When you are writing app that generates complex things via LLM - like websites, articles, presentations, code, stories, songs,...
  • When you want to separate code from text prompts
  • When you want to describe complex prompt pipelines and don't want to do it in the code
  • When you want to orchestrate multiple prompts together
  • When you want to reuse parts of prompts in multiple places
  • When you want to version your prompts and test multiple versions
  • When you want to log the execution of prompts and backtrace the issues

โž– When not to use

  • When you have already implemented single simple prompt and it works fine for your job
  • When OpenAI Assistant (GPTs) is enough for you
  • When you need streaming (this may be implemented in the future, see discussion).
  • When you need to use something other than JavaScript or TypeScript (other languages are on the way, see the discussion)
  • When your main focus is on something other than text - like images, audio, video, spreadsheets (other media types may be added in the future, see discussion)
  • When you need to use recursion (see the discussion)
