GPT-4: Everything You Need to Know (2023)

Gathering information about GPT-4 can be overwhelming due to its broad range of topics. To assist with sorting through the information, we have provided a table below. Please refer to it if you need to quickly find information on a specific aspect of the model.

What is GPT-4?

In simple terms, GPT-4 is the latest addition to OpenAI’s large language model systems (LLM). These systems aim to predict the next word in a sentence and intelligently incorporate their inputs. By studying a vast dataset, they can identify patterns and use them to improve their performance.

Compared to its predecessors like GPT-3 and 3.5, GPT-4 is expected to be a significant improvement. It boasts several specific enhancements that we will explore further below. Notably, this new model will enhance the capabilities of chatbots like ChatGPT and MS Bing, enabling them to provide better responses, more creative designs, and improved performance with both old and new ChatGPT prompts.

GPT-4 Is Multimodal

One of the most notable features of GPT-4 is that it is multimodal, a significant improvement over previous models. While earlier models could only interpret text inputs, GPT-4 can now handle prompts containing both text and images.

This means that GPT-4 can not only receive images but can also interpret and understand them. This capability applies to prompts that include both text and visual inputs. Additionally, GPT-4’s multimodal capability extends to all types and sizes of images and text, including documents with text and photos, hand-drawn diagrams, and screenshots. Despite this multimodal input, GPT-4’s output remains as effective as it is with text-only inputs.

GPT-4 Demostration

During a developer livestream hosted by OpenAI, the company demonstrated GPT-4’s multimodal capabilities.

In the stream, GPT-4 was given a screenshot of a Discord window and asked to provide a detailed description. GPT-4 produced an incredibly precise and detailed response in just over a minute, capturing nearly every aspect of the input screen, from the server name in the top left corner to the various voice channels and even identifying all online Discord members in the right pane.

It’s astonishing that GPT-4 was able to generate functional code for a website, and that pressing buttons on the site would reveal jokes. What’s truly mindblowing is that this was achieved through a combination of text and image inputs, including the model’s ability to decipher human handwriting. GPT-4’s ability to handle multiple types of input is a major step towards AI being able to understand prompts accurately and deliver precise results.

Although there were no major issues with the code, OpenAI acknowledged that GPT-4 could benefit from improvements in speed, which may take some time to achieve. Additionally, the model’s visual input capabilities are still being researched and are not yet publicly available.

How Is GPT-4 Better than GPT 3.5/ GPT-3?

Incredible as it may seem, GPT-4 successfully generated working code based on the input provided. Testing the code resulted in a fully functional website where pressing buttons revealed the jokes. GPT-4’s ability to decipher human handwriting and produce code from a combination of text and image inputs is truly remarkable. This multimodal capability represents a significant advancement in AI’s ability to comprehend prompts and deliver accurate results.

1. Better Understanding Nuanced Prompts

While the test produced no significant issues, OpenAI has acknowledged that GPT-4’s speed could be improved and that visual inputs are still in research preview and not publicly available.

Better Understanding Nuanced Prompts

Aside from its remarkable multimodal approach, GPT-4 surpasses its predecessors in various other areas. For instance, it can better comprehend nuanced prompts, a skill that is not immediately apparent when comparing it to GPT-3.5. To illustrate this point, OpenAI subjected both models to a battery of human-level exams without any specific training. The results demonstrated GPT-4’s superior performance over GPT-3.5.

2. Exponentially Larger Word Limit

The data speaks for itself and shows that GPT-4 outperformed its predecessor in all the exams. While some exams, like SAT EBRW, only saw a minor improvement, there was a significant leap in performance for other exams such as the Uniform bar exam, AP Chemistry, and more. OpenAI reported that “GPT-4 is also more dependable, innovative, and capable of handling nuanced instructions than GPT-3.5,” indicating that the bot can effortlessly comprehend more intricate prompts.

GPT-4 brings two significant improvements over its predecessors. Firstly, it can process inputs with an astonishing word limit of 25,000, which is significantly larger than GPT-3.5’s limit of 8,000 words. This means that users can now provide the bot with more detailed and lengthier inputs for it to analyze and generate responses. This is excellent news for developers, who can use new APIs and documentation to enhance their chatbots and obtain assistance in writing and fixing code.

3. Supports more languages

Secondly, GPT-4 supports more than 26 different languages, including Ukranian, Korean, Germanic languages, and many others. This is a substantial improvement over ChatGPT, which was primarily used by English speakers worldwide.

GPT-4 Supports more languages

OpenAI evaluated GPT-4’s performance on MMLU benchmarks by translating them into multiple languages. Results showed that out of 26 languages, GPT-4 outperformed GPT-3.5’s English-language performance in 24 of them. However, further data training is necessary before GPT-4 can fully support all languages.

4. Different Personalities

GPT-4 brings the concept of steerability to a whole new level. This means that developers can now instruct the AI to act in a certain way with a specific tone of speech. For instance, one can ask ChatGPT to behave like a cowboy or a police officer by assigning it a particular role using the ChatGPT API. GPT-4 is designed to maintain its character while having steerability, and OpenAI is working on making the system message more secure as it is susceptible to jailbreaking. Additionally, developers can now establish their AI’s style right from the start by describing the directions in the system message.
