  1. GPT Builder Overview

    The GPT Builder is the cornerstone of your custom GPT journey. It's a user-friendly interface that guides you through the process of crafting your model. With the GPT Builder, you start by defining the purpose and personality of your GPT. You'll be prompted to input the basic parameters that will shape your AI's interactions. It's where you decide how formal, humorous, or professional your GPT should be.

    Let's open the GPT builder. GPT Builder We'll start by providing the first prompt, let's build a dad joke assistant.

Later on you can edit every aspect of your GPT, in the configuration menu. Rename Proposal

  2. Profile Picture Creation

    One of the unique features within the builder chat is the ability to create a profile picture using DALL-E 3. This feature brings a visual identity to your GPT, making interactions more engaging and personable. The profile picture can be generated on the fly during a conversation, providing a dynamic way to visualize your AI.

    After collecting initial information the GPT Builder will generate a profile picture for your GPT. Profile Picture Generation Start When finished the profile picture will be shown to you. You can choose to accept the generated profile picture or upload a custom one. You can also send prompts to edit the profile picture, this will then also be handled by DALL-E 3.

    After shaping the initial behavior of your GPT, the builder will ask you further questions to refine its personality. You can choose to enable or disable certain actions, such as the ability to tell jokes or generate images. The builder also allows you to upload files that will be accessible to your GPT during conversations. These files can be used to provide context or to enhance the GPT's responses.

It allows you to interact with your GPT as if you were a user, providing insights into its behavior and allowing you to make necessary adjustments before finalizing.
