What are GPTs & How to Create Your Own GPT (Jan 2024)


Picture having the ability to create your smart helper, perfectly adapted to your needs, all without needing to code. OpenAI recently unveiled GPTs, Custom AI models that put the power of customizing AI into everyone's hands.

During the DevDay event on November 6th, OpenAI introduced GPTs, a significant leap forward in AI. These models, called Generative Pre-trained Transformers, are reshaping how we personalize AI applications.

Unlike regular AI, GPTs allow users to create tailored ‘agents' or smart assistants, building on the technology behind ChatGPT. What makes them special? They can smoothly use the internet, be creative like DALL-E, and tap into OpenAI’s Code Interpreter tool to do more.

The real magic of GPTs is their flexibility, as they can learn specific topics and perform set tasks, making them super useful in many parts of life and work. Let's take a closer look at GPTs, exploring how they can change how we work and make daily tasks easier, even for those without coding skills.

Understanding What are GPTs

What are GPTs

Generative Pre-trained Transformers, or GPTs, are part of a group of smart language models using advanced learning techniques to generate natural-sounding text. They take a sentence as input and craft a whole paragraph using information from publicly available data.

These models are incredibly versatile and can handle various text inputs, from regular paragraphs to coding and creative writing. They offer insights, analysis, or summaries based on the given text.

OpenAI's GPTs introduce a novel way to create personalized versions of ChatGPT tailored to specific needs. They can be used in diverse scenarios like teaching, gaming, or creating visual content, and the process of making them is free of coding expertise. Users start by guiding the conversation, providing additional information, and choosing what the GPT should do, whether searching the web, creating images, or analyzing data.

How do GPTs Work?

How do GPTs Work

GPTs undergo a fascinating process of understanding and generating text. They are trained using deep learning, where they digest massive amounts of internet data, forming connections and patterns. Unlike humans, GPTs break text into tokens for comprehension. Each word translates into a token, and longer words can split into multiple tokens. GPTs are trained on an immense 500 billion tokens to learn language patterns.

The magic lies in GPT-3's neural network, modelled after the human brain. This network has 175 billion parameters that help it understand and respond to prompts. It employs a transformer architecture, focusing on self-attention, where it scans all tokens in a sentence simultaneously, allowing it to pay attention to relevant words regardless of their position in the text.

Each token is encoded as a vector, a numerical representation with direction and position. The closer these vectors are, the more related GPT-3 considers them. This encoding helps the AI distinguish between different meanings of the same word. By employing multiple layers of self-attention mechanisms, GPTs weigh the importance of words in a sentence, capturing context and crafting responses that fit the given input.

Uses of GPTs

GPT models are like versatile virtual assistants capable of handling various tasks involving language. They are not just about generating text but also multi-skilled tools that can do a lot:

  1. Language Translation: These tools facilitate text translation from one language to another. They can provide accurate translations, enabling communication across different linguistic boundaries.
  2. Text Summarization: GPTs excel in summarizing lengthy passages or documents. They extract the most crucial information, condensing it concisely, aiding in quick comprehension or reference.
  3. Content Creation: These tools are adept at generating diverse content, ranging from short blog posts to lengthy articles. They assist in producing written material across various lengths and formats, catering to different content needs.
  4. Content Editing: GPT-based tools help refine content by adjusting its tone, style, and grammar. They enhance the overall quality of written text, ensuring it aligns with desired styles or preferences.
  5. Conversational Responses: GPT-based tools can engage in dialogue, providing responses that sound natural in conversations. For instance, they can answer questions as if conversing with a person, making interactions more human-like.
  6. Multimedia Skills: Newer GPT versions work with images, allowing tasks like blog post creation, content editing, summarizing text, language translation, and idea generation.
  7. Coding Assistance: They understand and write code, making it easier for learners to grasp programming concepts and offering code suggestions to experienced developers.
  8. Data Analysis: Business analysts use GPT models to sort data and present results in tables, charts, or reports.
