🤍 The Promptbook Whitepaper

If you have a simple, single prompt for ChatGPT, GPT-4, Anthropic Claude, Google Gemini, Llama 2, 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 drift, word repetition repetition repetition repetition or misuse, lack of context, or just plain w𝒆𝐢rd responses. When this happens, you generally have three options:

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

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

Separates concerns between prompt-engineer and programmer, between code files and prompt files, and between prompts and their execution logic.
Establishes a common format .ptbk.md that can be used to describe your prompt 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.
Has 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.
Promptbook has built in versioning. You can test multiple A/B versions of pipelines and see which one works best.
Promptbook is designed to do RAG (Retrieval-Augmented Generation) and other advanced techniques. You can use knowledge to improve the quality of the output.

🧔 Pipeline (for prompt-engeneers)

Prompt book markdown file (or .ptbk.md file) is document that describes a pipeline - a series of prompts that are chained together to form somewhat reciepe for transforming natural language input.

Multiple pipelines forms a collection which will handle core know-how of your LLM application.
Theese pipelines are designed such as they can be written by non-programmers.
