A Prompt Library is a library of high-quality prompts ready to be used to give instructions to generative AIs such as ChatGPT. It allows you to obtain the best results without having to start writing prompts from scratch for each request. Find out everything you need to know!<\/strong><\/p>\n\n\n\n

Generative AIs such as DALL-E<\/a>, ChatGPT and MidJourney offer tremendous possibilities… as long as you know how to talk to them! These powerful tools are capable of generating images, text, audio or even computer code. All you have to do is ask them using a natural language query: the prompt.<\/strong><\/p>\n\n\n\n

However, to create content that corresponds exactly to what is expected, it is often necessary to formulate the request in an extremely precise and detailed way. This can be tedious, and often requires you to try multiple iterations of the same prompt until you are satisfied. Generating a large quantity of elements can therefore quickly become a mammoth task.<\/p>\n\n\n\n

Fortunately, there are already complete collections of prompts already written for a wide variety of use cases, with the possibility of modifying them to meet specific needs: Prompt Libraries.<\/strong> After a brief look at the concept of prompts, we’ll introduce you to the best existing libraries and explain how to create your own Prompt Library<\/strong>. Follow the guide!<\/p>\n\n\n\n

Prompt engineering, or the art of talking to AIs<\/h2>\n\n\n\n

A prompt is a mode of interaction between a human and a large language model<\/a> (LLM) that allows AI to generate the desired result. It can take the form of a question, a text, an example or even an extract of computer code. Its complexity can range from a single word to a complete paragraph. For each prompt, an AI<\/a> can provide several results based on the way in which the prompt is formulated. The aim is to provide enough information for the model to produce a relevant result. This can be used to generate text, images, translate sentences, or obtain information and answers to questions.<\/p>\n\n\n\n

Each time an AI model<\/a> receives a prompt, it uses the knowledge it has acquired from its training data to generate a contextually relevant response. This is known as inference, and involves calculating probabilities and correlations between various sequences of words. The more specific a prompt, the closer the generated result will be to the desired one. To produce a text, for example, you need to specify the type, subject, tone, target audience and number of words.<\/p>\n\n\n\n

Whatever the use case, it is essential that prompts are carefully crafted to achieve the desired level of relevance and accuracy. This is Prompt Engineering.<\/strong> However, rather than racking their brains to build a new prompt every time they use AI, experienced users know that there is a solution that can speed up the process…<\/p>\n\n\n\n

The Prompt Library: a catalogue of ready-to-use prompts<\/h2>\n\n\n\n

A Prompt Library<\/strong> is a digital platform that allows users to share or sell the prompts they create to other users for various AI tools. So if you’re talented at engineering prompts, you can take advantage of these platforms to reach a wide customer base and increase your profits. It is also possible to buy prompts created for different use cases. This means you can get professional-quality prompts.<\/p>\n\n\n\n

Some platforms also offer free prompts.<\/strong> If you are just starting out as a Prompt Engineer,<\/strong> this is also a good opportunity to examine the prompts created by experts and improve your own.<\/p>\n\n\n\n

What are the advantages?<\/h2>\n\n\n\n

Such a collection of prompts<\/strong> enables consistent results to be obtained from one session to the next, optimised prompts to be preserved for specific tasks, and the prompt engineering process to be partially automated. All prompts are organised and centralised in a single location, making them easy to find when you need them. This centralisation eliminates the need to search multiple separate sources.<\/p>\n\n\n\n

It also improves the performance of generative AI,<\/a> thanks to prompts that are specifically designed for use cases or applications. This also reduces the risk of errors. What’s more, in addition to being a valuable resource for the prompt engineer,<\/strong> it is also an asset for collaboration<\/strong> and knowledge sharing between professionals in the sector.<\/p>\n\n\n\n

Prompt Hero, FlowGPT… the best Prompt Libraries<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

There are already many Prompt Libraries<\/em>. Here are a few of the most popular. One of the best known is PromptHero, where you’ll find prompts for ChatGPT, MidJourney<\/a> and StableDiffusion. These are mainly prompts designed for image generators. Users also share the number of steps, sampling methods and other information about the process used to obtain the shared result.<\/p>\n\n\n\n

PromptBase sells and buys prompts for the main IA models, such as DALL-E<\/a>, GPT, Stable Diffusion and MidJourney. The platform takes a 20% commission on each sale, and prices range from $1.99 to $9.99. There is also the FlowGPT platform, dedicated entirely to ChatGPT prompts. You can test the prompts directly on the website to check the results. A large part of the catalogue is available free of charge.<\/p>\n\n\n\n

Generative AI is still a new technology, and many new libraries of prompts will be created over time! However, it is also possible to create your own custom Prompt Library.<\/strong><\/p>\n\n\n\n

Designing a Prompt Library<\/a><\/div>\n<\/div>\n\n\n\n

How do you create your own Prompt Library?<\/h2>\n\n\n\n

If you want to create your own Prompt Library,<\/strong> use a spreadsheet tool such as Excel or Google Sheets to store your prompts. This will enable you to find them easily thanks to the search and sort functions! You can also sort your prompts by category, subject or frequency of use. A good library should be made up of an assortment of recipes and prompts, to facilitate creation and testing.<\/p>\n\n\n\n

The first step is to clearly identify the purpose and scope of your Prompt Library. Take into account the type of project and the use cases for which you will need this catalogue. You can write your own prompts, or aggregate them from various sources such as online Prompt Libraries<\/strong> or other existing projects.<\/p>\n\n\n\n

Conclusion: the Prompt Library, a veritable toolbox for the generative AI professional<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

By avoiding the need to create a new prompt each time generative AI is used, the Prompt Library saves the prompt engineer precious time.<\/strong> So it’s a mine of resources to draw on indefinitely. And if you’re good at creating prompts, you can even sell them to other users. While it is possible to use the many catalogues available on the web, creating your own library allows a higher level of customisation.<\/p>\n\n\n\n
