What is ChatGPT-4

ChatGPT-4 is the latest conversational AI model developed by OpenAI. This product, released on March 15, 2023, has a significant improvement over the previous generation of GPT-3.5.

GPT-4 is developed to improve AI's natural language processing capabilities and achieve dialogue closer to humans. The increase in the number of parameters allows it to handle more complex text comprehension and text generation tasks . In addition, new features such as generating images based on text input are also added.

GPT-4 has strong contextual understanding ability and can achieve more humane natural dialogue. It is expected to be widely used in many fields such as education, medical care, customer service, and creation.

Multimodal function	Text only	In addition to text, you can also understand and generate images

As can be seen from the above table, all functions of ChatGPT-4 have been enhanced.

Here are four key points :

• 1. Contextual understanding ability
• 2. Multimodal function
• 3. A significant increase in the number of available characters
• 4. The accuracy and security of the output

1. Contextual understanding ability

GPT-4's context comprehension ability has been significantly improved. In the US Unified Bar Exam, the score of GPT-3.5 is only around the bottom 10%, while the score of GPT-4 is at the top 10% (the sixth from the left of the chart).

In other exams, GPT-4 (red) also achieved better results than GPT-3.5 (blue).

UBE-GPT4

In addition, studies have shown that issuing instructions to GPT-4 in Japanese can achieve better contextual understanding than issuing instructions to GPT-3.5 in English.

This shows that GPT-4's language comprehension ability has improved in various languages .

2. Multimodal function

GPT-4 is a multimodal AI that integrates image analysis and voice output functions. Therefore, it can realize image input/output, voice input/output functions that cannot be achieved by GPT-3.5.

This has led it to evolve from a traditional text-based conversation to an AI with vision and hearing.

3. Maximum number of characters input/output

Compared with GPT-3.5, the number of characters that GPT-4 can process at a time has increased significantly.

• GPT-3.5
  The maximum number of characters that can be processed in a conversation is usually within a few thousand characters. When processing large data, it needs to be divided into multiple requests for processing.
• GPT-4
  A maximum of 4096 tokens (about 16000 characters) can be processed in a single request. Therefore, even long text or complex conversations can be processed smoothly.

4. The accuracy and security of the output

Compared with GPT-3.5, the output accuracy and security of GPT-4 have been significantly improved.

First, GPT-4 reduces the phenomenon of hallucination (generating non-existent facts or data). This is achieved by improving data quality, improving training methods, and leveraging large datasets for deeper learning.

Therefore, users can have higher trust in GPT-4's answers.

Additionally, GPT-4 is set to reject content that may be discriminatory, seditious, or offensive. Therefore, GPT-4 can provide a safe and ethical response.

What can ChatGPT-4 do

Compared with GPT-3.5, GPT-4 has made significant improvements in the following aspects:

• 1. More advanced text creation .
• 2. Image recognition and generation
• 3. Advanced programming and chart creation

Each feature will be explained in detail below.

1. More advanced text generation

Compared with GPT-3.5, GPT-4 is able to generate more natural and complex text. Because GPT-4 uses larger datasets for training and has stronger contextual understanding, the generated text is more consistent in terms of text fluency and logical structure.

For example, when using GPT-4 to generate novel clips, it can take into account the character's personality and story background and generate natural dialogue and description. In addition, GPT-4 is able to properly use professional terms and complex concepts and is therefore suitable for writing academic papers and business reports.

GPT-4's advanced text generation ability can assist writers, editing, translation and other language-related professionals and improve efficiency. In addition, in the field of education, it can also be used to correct students' compositions or create teaching materials.

2. Image recognition and generation

ChatGPT-4 uses DALL-E3 to realize the image generation function. For example, after entering an image, it can recognize and describe the image.

GPT image description

Using the image input function, you can ask questions about uploaded images. For example, it may be required to recognize objects in the image, or to describe the scene of the image. ChatGPT-4 analyzes images and provides relevant text information.

In addition, it also has the function of generating similar images. For example, if you ask it to convert a photo into an illustration or generate a similar image, you will get the following results:

Things to note when using ChatGPT-4

Although ChatGPT-4 has various powerful functions, the following points should be noted when using it:

• 1. The duration of training data
• 2. Error in output content
• 3. Processing of input data

The following will explain in detail.

1. The duration of training data

The training data for GPT-4 is as of April 2023, so it is impossible to directly answer events or information that occur after this date.

However, the latest information can be obtained through web browsing features or specific plugins. With these features, GPT-4 can access the latest news and information and provide answers based on these contents.

Plugins and browsing

Additionally, API-only GPT-4 Turbo has training data as of April 2024 , so it can provide updated information.

2. Error in output content

The AI ​​will learn the input data and generate content based on it. Therefore, so-called hallucinations may occur, i.e., misinformation or biases will be reflected in the results.

Reference: OpenAI

Although technological advances make it possible for AI to automatically fact verification, manual judgment is still crucial at this stage. To make the most of the convenience of AI, fact-checking must be conducted to ensure its accuracy.

Especially when used in business or research fields, you should not blindly believe in the output of AI, but should always be manually verified.

Example of hallucination

3. Processing of input data

The information entered into ChatGPT may be used for machine learning, so attention should be paid to the processing of confidential information in the enterprise. In fact, there have been cases where employees of Samsung Electronics entered confidential information into ChatGPT, causing company information to be leaked.
