These models are trained with vast amounts of text, learning to recognize patterns and meanings in human language. ChatGPT stands out for its ability to generate responses that are not only sensible but also relevant and contextually appropriate, a notable feat in the field of AI.

The functionalities and necessary concepts of ChatGPT

ChatGPT is an AI chatbot that offers various functionalities to its users, both in the free and Plus versions. Some of the main functionalities are:

  • Conversing about any subject: you can ask or talk about anything you want with ChatGPT, from curiosities, facts, news, opinions, hobbies, to personal, professional, emotional, or existential issues. ChatGPT will try to respond appropriately, informatively, educationally, entertainingly, or empathetically, depending on the context and your mood. You can also choose from different personalities and conversation styles for ChatGPT, like formal, informal, serious, playful, sarcastic, optimistic, pessimistic, and so on.
  • Learning about any topic: you can ask ChatGPT to teach or explain any topic you are interested in or struggling with, such as mathematics, physics, chemistry, biology, history, geography, literature, philosophy, art, music, or languages, for example. ChatGPT will use simple and didactic language, and provide examples, exercises, tips, and resources for better learning. You can also choose from different levels of difficulty and depth for ChatGPT, like basic, intermediate, or advanced.
  • Creating original content: you can ask ChatGPT to create or generate original content for you, like texts, images, song lyrics, and video scripts. ChatGPT will use its creativity and knowledge to produce unique and interesting content, according to your specifications and preferences. You can also choose from different types and formats of content for ChatGPT, like poetry, prose, essay, article, code, logo, meme, song, parody, etc.
  • Performing various tasks: you can ask ChatGPT to do or help do various tasks for you, such as planning a trip, organizing a schedule, making a reservation, purchasing a product, negotiating a price, or training for a test, for example. ChatGPT will use its intelligence and skill to perform or assist in tasks, according to your needs and goals. You can also choose between different degrees of autonomy and interaction for ChatGPT, like delegating, collaborating, or consulting.

To utilize these and other functionalities of ChatGPT, it’s important to understand some key concepts, such as:

  • GPT: GPT is the natural language model that ChatGPT uses to process and generate texts. There are two versions available: GPT-3.5 and GPT-4. GPT-3.5 is the free version, using GPT-3, the third model in the GPT series, with 175 billion parameters. GPT-4 is the Plus version, using GPT-4, the fourth and most recent model in the GPT series. GPT-4 is more advanced and powerful than GPT-3.5, offering more functionalities and possibilities for ChatGPT.
  • Custom GPT: Custom GPT is a version of GPT that has been trained for a specific purpose, such as creative writing, marathon training, travel planning, or math tutoring. ChatGPT offers hundreds of custom GPTs for you to choose from, or you can create your own GPT without needing code, just simple instructions. Custom GPT can improve the quality and relevance of ChatGPT’s responses, according to your goal and interest.
