How is GPT-4 different from ChatGPT, and what makes it unique?

• ChatGPT, the popular AI chatbot, is powered by GPT-4, launched on March 14th as the successor to GPT-3.
• GPT-4 can process up to 25,000 words, eight times more than its predecessor GPT-3, and can handle more nuanced instructions and images.
• GPT-4 is currently accessible through ChatGPT Plus, which costs $20 per month.

San Francisco-based artificial intelligence lab OpenAI has unveiled its latest creation, GPT-4. The company is renowned for its viral chatbot ChatGPT. According to their recent blog post, the new version is ‘multimodal,’ meaning it can process image and text inputs and generate text outputs.

Chat GPT-4's primary function is generating text, but it excels at it to a remarkable degree. OpenAI says this latest version can process up to 25,000 words- about eight times as many as GPT-3. Also, it can process images and handle much more nuanced instructions than GPT-3.5.
How does ChatGPT Compare to GPT-3 and GPT-4?
ChatGPT is an AI chatbot that utilizes the language models of GPT-3 and GPT-4 for interactive communication. In other words, GPT-3 or GPT-4 serves as the engine that powers ChatGPT, much like an engine powers a car.

GPT-3 was first released in 2020 and boasted an impressive 175 billion parameters, making it the largest neural network ever produced. It was subsequently fine-tuned with the GPT-3.5 series in 2022.

GPT-4, launched on March 14th, is the successor to GPT-3. According to OpenAI, it can process up to 25,000 words, which is about eight times more than GPT-3. Additionally, it can process images and handle more nuanced instructions than GPT-3.5.
How can you access GPT-4?
If you're new to ChatGPT, the first step is to visit chat.openai.com. You can create a free account that grants you access to GPT-3, the current version available to everyone.

To use GPT-4, however, you'll need to subscribe to ChatGPT Plus, which costs $20 per month and provides premium access to the service. Currently, there's a limit of 100 messages every four hours when using GPT-4.
What are the new capabilities of GPT-4?
OpenAI says that GPT-4 is good at tasks requiring advanced thinking, understanding of complex instructions, and creativity. People have already started using it for different creative tasks since it was launched a few hours ago; these include the following use cases.
Describe images and generate recipes

GPT-4 can process images, meaning users can upload photos and get recommendations from GPT-4 based on the image. For example, if you upload a photo of flour, butter, eggs, and milk, GPT-4 can suggest some recipes that can be made with those ingredients. However, this feature is not currently available to the public.
Code video games

Users on Twitter have shown that GPT-4 can code complete video games in just a few minutes, even without prior knowledge of popular programming languages like JavaScript. An example is a user who recreated the classic game Snake using GPT-4's capabilities.
Create websites

As shown above, a functional HTML page was created from a hand-drawn sketch using GPT-4.
Create a functional Chrome extension in just a few hours

Without prior knowledge or coding experience, users create a Chrome extension in just a few hours.
What comes next?
Microsoft Corp. has committed $10 billion to OpenAI, but other tech companies also compete in AI. Google has introduced its own AI service, Bard, to testers, and numerous startups are also striving to keep up with the pace of AI development. In China, Baidu Inc. is set to release its own bot, Ernie, while Meituan, Alibaba, and other smaller companies are also entering the fray.
