Let's take a moment to dive a little deeper and examine three concepts without which our current AI conversation would be meaningless…

‍

Machine Learning: The Core of AI‍

At the heart of AI lies Machine Learning (ML), a subset of AI that empowers machines to learn from data without explicit programming. ML algorithms use statistical techniques to identify patterns in data, enabling them to make predictions or decisions based on new information. This ability to learn and improve with experience is what sets ML apart and makes it a powerful tool in various applications.

Prompt Engineering: Igniting Creativity in AI

Prompt engineering is a fascinating aspect of AI that involves crafting effective instructions or queries to direct AI models' output. By providing appropriate prompts, developers can influence the content, style, or tone of AI-generated outputs. This technique has been particularly instrumental in the development of Generative AI.

Generative AI: Fostering Creativity

Generative AI is a branch of AI that deals with machines' capability to create new content, such as images, music, text, and more.

In simpler terms, Generative AI is precisely the branch that has recently gained immense popularity thanks to tools like ChatGPT, MidJourney, DALL-E, or Jasper. As the name suggests, it's generative, meaning it can generate (or just create) new content based on specific queries, known as prompts.

But how is this even possible? In a nutshell, by learning patterns from a vast amount of data (such as existing articles, research papers, images, and more), the algorithm creates new content based on these patterns. Importantly, even though we "feed" the algorithm with certain content (pre-trained data sets), it doesn't mean we'll get copies or similar replicas of the input. The algorithm, using learned transformations, can iteratively generate genuinely new things. It's all powered by deep neural networks, but the exact workings and why the algorithm produces a specific response are not obvious, even to the creators of these neural networks. You input the data, and run the algorithm, but what happens inside the network remains a puzzle.

ChatGPT - What's All the Buzz About?

Imagine having a super-smart assistant, like a virtual wordsmith, at your fingertips, ready to help you create captivating content and answer your queries. That's precisely what ChatGPT is!

ChatGPT, developed by the American company OpenAI, is a content generator that relies on a large language model called GPT (currently in version 3.5 or, paid GPT-4). It's a bot with which you can communicate using natural language. This tool over 50 different languages, capable of answering questions, translating documents into various languages, conducting proofreading and language editing of texts, summarizing and analyzing scientific papers, suggesting solutions to diverse problems, crafting essays, scripts, debugging programming code, and searching through databases. In the paid version of the tool, you even have the ability to work with images, allowing you to upload an image as input and, for example, expect its analysis.

What's crucial is that the paid version of ChatGPT (GPT-4) now has (or, compared to the competition, is just getting) internet access. This means it can now browse the internet to provide you with current and authoritative information, complete with direct links to sources. It's no longer confined to data from before September 2021. Additionally, we can utilize various plugins and integrations, such as speech recognition (Whisper) and complex data calculations and analysis (Wolfram Alpha), making the tool even more powerful. Currently, there are over 900 plugins available!

Recently, ChatGPT also received an update that enables the ability to converse with the chatbot using voice commands. ChatGPT, GPT-3.5, and GPT-4 will be able to comprehend user questions and respond using one of five distinct voices.

‍

Now, you might wonder why you should use ChatGPT. The answer is simple: it saves you time and boosts your productivity. Writing high-quality content can be time-consuming, and not everyone has the expertise to craft captivating texts. ChatGPT eliminates that hurdle, offering instant assistance whenever you need it. Furthermore, it helps overcome writer's block, as it can spark new ideas and inspire creativity. 

In short, ChatGPT can help us with a range of tasks, including:

• Brainstorming
• Exploring various options for what we want to do
• Providing suggestions regarding different approaches, for example, how to do something on iOS or Android
• Fueling creativity: X ideas for headlines, X ideas for navigation in the design industry, and so on…
• Writing meeting summaries
• Preparing transcriptions
• Making analyses
• Sprint management
• Customer service
• Delivering corporate wiki - uploading documentation to the AI model and using queries to direct to specific places, like where the button component is located
• And much more!

‍

Here are a few tips on how to effectively "converse" with Chat GPT (or any similar tool) to get the best possible responses:

• Write simple and uncomplicated sentences
• Break down sentences into shorter and more precise ones
• Describe the context of your problem in detail
• Start with the general idea and ask follow-up questions to refine your queries based on the response you receive
• Speak as if you were talking to a 5-year-old

‍

What is a noteworthy alternative to Chat GPT?

As you might imagine, the competition is not resting, and the market is flooded with a multitude of tools that utilize GPT models and more.

Currently, the two most popular tools, operating similarly to ChatGPT, are:

• Bing - Microsoft's chatbot that uses the same GPT model as ChatGPT, but integrates it with the Bing search engine. This means that it can access the internet by default and provide you with relevant information, sources, and suggestions. You can also change the tone of the chatbot to be more creative, more precise, or balanced;

• Bard - Google's chatbot that uses a combination of two language models: LaMDA and PaLM. LaMDA is designed for dialogue applications and PaLM is good at math and logic. Google Bard can also access the internet by default and display photos in the results. You can also export the results to Gmail or Google Docs, or modify them without typing. Google Bard is free and available for anyone to use.

The best chatbot for you depends on your needs and preferences. You might want to try them all and see which one suits you better. They are all amazing examples of how AI can help us communicate, create, and learn.
