How To Guide: GPTs 

How To Guide: GPTs

Following on from OpenAI’s Dev Day we wanted to showcase one of the major announcements from the conference, the introduction of GPTs.

GPTs are custom versions of ChatGPT that allow you to combine skills, instructions, and knowledge to perform most tasks that you could want, within the limitations of a large language model.

Creating these GPTs is very straightforward and does not require any programming knowledge or design skills. OpenAI has created a build assistant called “GPT builder” to help you through the process from start to finish, asking you the user, questions about the project that you are trying to create and offering helpful suggestions to shape your personal GPT.

It is important to note that at present GPTs are only available to ChatGPT Plus and Enterprise users, but OpenAI says that it will offer them to more users soon.

So let’s get started! Once you log into ChatGPT you will see a new ‘Explore’ tab on the left-hand sidebar, once you select this you will see the ‘My GPTs’ page below like the one below.

You will be able to see all of your previously created GPT’s here, and those shared with you along with those made by OpenAI,

But we want to create a new GPT of our own so select this option at the top of the page.

From here you will be taken to the starting point for creating your own custom GPT.

We can see the GPT builder on show here ready to guide us through the process.

What GPT to build?

For our demonstration, we are going to build an assistant to search through some of our recent blog posts and to give us useful insights.

Here are some tips for choosing what kind of GPT to create if you get stuck:

• What is the problem you are trying to solve? In the same way that you use ChatGPT, a GPT is there to help with completing tasks and to act as an assistant in a lot of cases.
• How do you want it to sound? Think about the tone, style and directness of your GPTs answers, do you want it to explain things like a professor or a pirate, and would you like it to ask you questions or to give you straight and short answers?
• Use existing material: You can add materials like PDFs, research material, lists and emails to your GPT to tune it to get the most out of your personalised assistant.
• Do you want it to deliver answers in a specific way? You can specify if you would like your answers presented in lists, tables or another format.

 

My first GPT

Ok, let’s start creating our GPT using the GPT Builder assistant. We mentioned that we were going to create an assistant to search through some of the recent NCAITE blog posts, looking for themes, insights and to be a search tool and explainer on the topics covered.

The builder will then get to work creating our custom GPT, and will suggest a name for itself, which you can choose to change, as we will in our case. You can communicate using natural language, and the GPT Builder is extremely responsive.

It will get to work on generating a profile picture using Dalle3 for our GPT. You can change this if it is not what you had in mind and it will generate a completely new image for you.

Ok so with the new profile picture generated, we are ready to move on to the next steps in the building of our GPT. The builder will now prompt you to give our tool some more context to make it meet our requirements.

You can inform it on the level of detail in answers you would like it to deliver, and the way that you would like it to deliver it. We have selected a tone that is a mix of friendly and formal, with a high level of flexibility.

Now I’m going to give our GPT some specific training data, for our example, we will be training it on some of our blog posts from the NCAITE Website. I will provide these as PDFs which I can just drop into the text box, or we can add them as attachments.

We are now ready to test our GPT in the preview playground on the right-hand side, the build assistant has helpfully offered up some conversation starters. If we move to the Configure tab we can see what the GPT builder has put together for us and can make any tweaks and alterations, including to the Conversation starters, Knowledge, and further down we can choose whether to allow for features such as Dalle, Code interpreter and Web Browsing.

Once happy with the configuration of our GPT we can test it in the Preview screen.

If there are any further amendments that you want to make to the GPT you can revisit the Builder to instruct it to fine-tune the GPT further to meet our requirements.

But for now, we will save our draft GPT using the green Save button in the top right corner.

And that’s it, our GPT is now live and ready to be used for finding insights and explanations from our blog posts. Remember, if you would like to make any further changes you can edit it using the drop-down in the top left-hand corner and selecting edit. You can also share your GPT for others to use (providing they are ChatGPT+ or enterprise users presently).

Remember, users of the GPT will be able to access the material it was trained on along with the prompts used in creating it, so don’t put anything in that you wouldn’t want to be public.
