Step 2: Interface with the GPT builder:
Next, you will need to access the GPT builder through OpenAI to begin creating their custom GPT. Start by going to https://chat.openai.com/ and logging into your account.
Once logged in, click on Explore GPTs in the top left of your screen, which will take you to the GPT interface. This includes custom GPTs featured by OpenAI, categories of the top publicly available GPTs created by other users, and the option to see/create your own GPTs.
To begin the creation of a new custom GPT, click the +Create button at the top right of the page.
This will bring you to the GPT builder. In it, you will notice a pane on the left, and a pane on the right. The pane on the left is the builder, where you can interact via the message bar to upload documents and provide instructions to the model on what you want your GPT to be able to do. Users can begin by uploading their documents by clicking the paperclip in the message bar, or by providing a message to the GPT builder on what the main purpose of the GPT is.
The GPT builder will then respond with specific questions about the name, logo, and purpose of the GPT. Iterating several times with the GPT builder through natural conversation is recommended to provide the model with a clear understanding of what it should be doing.
Step 3: Iterate
The most important part of creating a custom GPT is iterating with the system until it produces the outputs and behavior that you desire. The GPT builder is meant to adjust the underlying behavior of the model, but if you want to see how your GPT actually behaves in its current state, you need the Preview pane, which is on the right side of the screen.
Imagine you have been talking with the GPT builder to provide instructions about how your model should behave. Now, you can go to the preview pane on the right side and actually prompt your current model as the user. You can then directly see how your GPT behaves, and then if some element is not satisfactory, you can go back to the GPT builder in the left pane and ask it to change things until the output is correct. Switching between the builder and preview panes allows for real-time iteration to improve the performance of your GPT.
Step 4: Set Up Advanced Configuration
In addition to creating and tuning your GPT using conversational language, GPT creators can also take steps to configure their GPT in more detail. To do this, click the Configure button in the top of the builder pane.
Once in the configure tab, you can see the name, description, and instructions underlying the custom GPT. In addition, there are options to add knowledge to the custom knowledge base by uploading additional files. This is equivalent to uploading files via the message bar within the GPT builder, and in the configure tab you can see all of the files uploaded thus far to the GPTs.
