What is GPT-4?
GPT-4, launched by OpenAI on March 14, 2023, is the next-generation version of the GPT model. This multimodal AI model is more advanced than its predecessor, GPT-3.5, and offers numerous improvements in various areas, including accuracy, steerability, and academic performance. It can process both text and image inputs, making it a versatile tool for various applications.
Here are some standout features of GPT-4:
1. Multimodal Capabilities
GPT-4 can accept both text and image inputs, allowing it to understand and generate text from complex images such as charts and memes. This is a major upgrade from GPT-3.5, which was limited to only text-based inputs.
2. Improved Accuracy
With better factual correctness, GPT-4 makes 40% fewer factual errors compared to GPT-3.5. It is also 82% less likely to generate disallowed or offensive content.
3. Steerability
GPT-4 offers improved steerability, allowing you to customize its behavior. You can adjust its style and tone using the "System" box, enabling more tailored and relevant responses.
4. Better Academic Performance
GPT-4 excels in academic performance, scoring higher on exams such as the Uniform Bar Exam, LSAT, and Biology Olympiad, showcasing its advanced problem-solving and reasoning capabilities.
How to Use GPT-4
To start using GPT-4, there are a few options available. Let's explore how to access this powerful tool.
Option 1: Join the GPT-4 API Waitlist
The first method is to gain access through the GPT-4 API. Currently, OpenAI is offering limited access via a waitlist. Once granted access, you can integrate GPT-4 into your applications using the API.
Here’s how you can join the GPT-4 API waitlist:
Visit the OpenAI website and click on "Product."
Select "GPT-4" to be redirected to the GPT-4 page.
Click on "Join API waitlist" and fill in your details to request access.
Option 2: Subscribe to ChatGPT Plus
Another way to access GPT-4 is by subscribing to ChatGPT Plus. This premium service provides access to GPT-4 for a monthly fee and is ideal for content creators, businesses, or anyone looking for more advanced AI capabilities.
Here’s how to subscribe to ChatGPT Plus:
Go to the ChatGPT platform.
Click on "Upgrade to Plus" at the bottom left.
Choose your plan and enter your payment details.
Once subscribed, you can select GPT-4 from the drop-down menu and start using it immediately.
How to Use GPT-4 for Free

Why Choose Writesonic Over ChatGPT Plus?
While GPT-4 offers incredible features, there are some drawbacks when using it with ChatGPT Plus. Here are a few reasons why you might consider Writesonic powered by GPT-4 instead:
Real-Time Content
ChatGPT is trained on data until September 2021, meaning it can't generate content on the latest topics. Writesonic, on the other hand, provides real-time data and content generation capabilities.
