Step into a realm where crafting top-notch applications no longer demands assembling a team of developers. Enter ChatGPT, a technological marvel poised to redefine the application development landscape. With more than 175 billion parameters, this language model is trained on a variety of Internet text, giving it unprecedented insight into human language. In one study, 63.5% of readers could not identify that chatGPT rather than a human wrote an article.

GPT-4 has proven to be the most potent multimodal model. It outperforms all existing AI models that work with different types of information by up to 10%. You can provide text, graphics, images, 3D models, video, or audio and get a specialist's answer as output.

Understanding GPT-4's Superiority in Multimodal Tasks

The results of the Open AI presentation were impressive. In online mode, the presenter drew a website layout on paper, took a picture, and sent it to GPT4. On request, the model deciphered the handwriting and created an entire website based on the proposed layout.

ChatGPT-4 can create a complete application. Just tell the model in general terms what you want your application to do. And she can program it all by herself.

For example, a user asked ChatGPT-4 to model an application that would recommend five new films daily. The application had to include a description, basic information about the film, a poster, and a link to where to watch it.

The generated code may not work correctly the first time. There are errors in a single line of code. But this can also be left to chatGPT-4. You can compile the code and copy the error message from the software environment.

The model will apologize and offer a new, corrected code. Consult the chatGPT guide on 'how to set up an app' to ensure a smooth and successful launch.

Today, you can find the chat GPT on the app store with enhanced features and easy access.

Application written by chatGPT

In this article, we're taking things up a notch by building a mobile application from the ground up using ChatGPT, all without predefined requirements. You'll gain insights on crafting precise queries for accurate and valuable responses. Get ready for an in-depth exploration into ChatGPT development, where we'll witness numbers transform into groundbreaking outcomes. Let's kick things off!

Launching Your App: Utilizing ChatGPT's Guidance

Before building your app, let's quickly learn a straightforward rule for effective chatGPT prompts. Compose your prompt by answering five questions:

  1. What do you want to get?
  2. Where will you use the answer?
  3. How should it be written (language, structure, tone of voice, emotion, length of response)?
  4. Why do you need the answer? For what purpose do you want to use it?
  5. Who is your target audience?

This rule will help you create high-quality chatGPT requests and receive, instead of standard extensive answers, unique and most effective results for you. Let's check this rule in our business - creating a mobile application.

The chatGPT response will be transformed if you add the phrase: "Let's think step by step" at the end of each request.

Below, we will show how to build an app for free.
