What is GPT 4?

What is GPT-4—a question that’s probably popped up in your head amidst all the hype surrounding OpenAI’s GPT-3 and ChatGPT.

OpenAI has revolutionized AI-powered systems, particularly those that use Natural Language Processing models. And with the release of GPT-4, OpenAI has taken these systems a step further.

GPT-4 is the latest GPT (Generative Pre-trained Transformer) series iteration that can process both text and image inputs for creating text outputs.

In this blog, we’ll explore:

• What is GPT-4?
• The difference between GPT-3 and GPT-4,
• GPT-4 release date
• GPT-4 accessibility, and more

So whether you’re an AI geek or simply curious about how the virtual world is changing, here's everything you need to know about this latest language model.

What are Generative Pre-trained Transformers?

Generative Pre-trained Transformers, a.k.a GPT, is an artificial intelligence language model from OpenAI that leverages deep learning technology to generate human-like text.

You can train the GPT models to perform various natural language processing applications such as:

• Language translation,
• Chatbot integration,
• Content generation,
• Text summarization,
• Sentiment analysis,
• Text-to-speech synthesis, and much more.

The applications of GPT models are limitless, and you can further fine-tune them on specific data to generate desired results.

What is GPT 4?

OpenAI's GPT 4 is the fourth multi-modal large language model in the GPT series. It can accept both image and text inputs to produce human-like text outputs in seconds.

According to OpenAI, GPT 4 is more reliable, creative, and capable of handling nuanced instructions than its predecessors. It also has other notable features, such as:

1. Ability to synthesize images as inputs

Unlike its predecessors, GPT 4 can accept and process images as inputs to create human-like text outputs.

You can use GPT 4 to identify the humor in images, summarize screenshots, answer questions with diagrams, etc.

2. Generate long texts in custom tones

GPT 4 can read, analyze, and generate up to 25,000 words of text.

It also allows you to set the tone of the generated text with system directive commands—you can ask the AI to create output with more rhymes and Shakespearean prose or even generate output only in JSON.

3. High aptitude level

GPT 4 AI has scored high aptitude on several standardized tests like SAT, LSAT, Uniform Bar Exam, etc.

During the testing phase, it passed a simulated bar exam, landing among the top 10% of test takers, while the GPT 3.5 model was at the bottom 10%—exhibiting the best-so-far human-level performance on various professional and academic benchmarks.

4. Coding capabilities in all major programming languages

It can write code in all major programming languages—Python, Java, .Net, and more.

How is GPT 4 different from GPT3?

GPT 4 is a definite upgrade from GPT 3 and even GPT 3.5. Apart from the unique capabilities mentioned above, here are a few other differences between these two large language models:

1. Training and data sets

OpenAI has trained GPT 4 on a larger data set than GPT 3. While GPT 3 contains only 17 gigabytes of data, GPT 4 has 45 gigabytes of training data.

This simply means GPT 4 can provide much more accurate results than GPT 3.

2. Size of the models

GPT 3 is a 175 billion parameter model, whereas GPT 4 is built on 1.6 trillion parameters. With the GPT 4 release, OpenAI enables you to solve more complex tasks using AI.

3. Applications

GPT 3 has changed the face of chatbots, virtual assistants, content generation, and research. GPT 4 is expected to significantly contribute to art, creative writing, long-form content, and music, along with upgrading the applications of those of GPT 3.

4. Performance

GPT 3 struggled with understanding sarcasm and idiomatic expressions. With the introduction of GPT 4, OpenAI intends to drastically improve its ability to generate human-like text that surpasses the limitations of GPT 3.

Here's a more detailed GPT-3 vs. 4 comparison.

GPT 4 release date and access

OpenAI released GPT 4 on March 14, 2023.

The GPT 4 API is not open to the public yet, and you need to join the GPT 4 waitlist to gain access.

Alternatively, ChatGPT Plus offers access to the OpenAI GPT 4 (with a usage cap). You can follow these steps to access GPT 4 with ChatGPT Plus.

Step 1: Go to the ChatGPT site - https://chat.openai.com/

Step 2: Login if you already have an account, or sign-up using your email address.

Step 3: Click on “Upgrade to Plus” on the left bottom side of the navigation bar.

A pop-up with available plans will appear. Click on Upgrade plan.

Step 4: Type your card details in the space provided and pay. You only need to pay $20/month for ChatGPT Plus Subscription.

Step 5: Select GPT-4 from the model after you’ve made the payment. You will have immediate access to the latest models. From the dropdown, select GPT-4.

Note that the GPT-4 version will be slower than its previous models, but the accuracy and quality of the outputs will be significantly high.

Final thoughts

There it is, all you need to know about the latest release in the GPT series, GPT-4—from what is GPT-4 to its capabilities and how you can access it, all in one place.

With its potential for more accurate and nuanced language generation, GPT-4 could be the right tool to significantly impact content creation, marketing, coding, and many more.

So, go forth, and explore this latest boom in AI technology to your advantage.
