GPT-4 vs GPT-3: The Face-Off

1. Improved Comprehension of Complex Prompts :

• According to OpenAI, it may not be immediately apparent how GPT-4 differs from GPT-3.5. However, the true capabilities of the latest model are evident when examining the fine details. In order to demonstrate this difference, GPT-4 was compared to GPT-3.5 in a series of human-level exams using the most recent publicly available tests. No specific training was given to the models for these tests.

• In all of the tests, GPT-4 surpassed its predecessor and achieved higher scores. Although some exams (such as SAT EBRW) only showed a slight improvement, there was a significant leap in performance in others (such as Uniform bar exam, AP Chemistry, etc.). OpenAI reported that "GPT-4 is also more dependable, imaginative, and capable of comprehending more nuanced instructions than GPT-3.5." As a result, chatbots powered by GPT-4 can effectively comprehend complex prompts with ease.

2. Significantly Larger Input Capacity :

• While GPT-3 and GPT-3.5 were highly acclaimed, users were limited in the length of inputs they could provide. The arrival of GPT-4 has resolved this issue with an impressive 25,000-word input capacity, which is exponentially larger than its predecessors. For comparison, GPT-3.5 was limited to just 8,000 words. This increased input capacity means that users can provide chatbots with much longer input prompts for the AI to process and generate more detailed responses. This feature will make it easier for developers to create new APIs and documentation for chatbots, as well as help them write code or debug existing code more efficiently.

3. Expanded Language Support :

• While ChatGPT has primarily served English speakers worldwide, GPT-4 expands its language capabilities to include over 26 languages, such as Ukrainian, Korean, and Germanic languages, among others. OpenAI conducted tests to verify this expanded language support, translating MMLU benchmarks into different languages. Out of the 26 languages, GPT-4 performed better than GPT-3.5 in 24 of them.

4. Controlled Personality :

• One of the new features of GPT-4 is steerability, which allows users to instruct the AI to act in a certain way with a fixed tone of speech. For example, a user can ask ChatGPT to act like a cowboy or a police officer. OpenAI has improved this feature in GPT-4, making it more difficult for the AI to break character. Developers can now define their AI's personality in the "system" message, ensuring that the AI stays in character. OpenAI is also working on improving the security of these messages.

• In one demo, a user attempted to get GPT-4 to stop being a Socratic tutor and simply provide an answer to their question, but the AI refused to break character. This showcases how developers can expect their bots to remain consistent in their personalities and behavior once trained with specific instructions.

Endless possibilities with GPT-4

GPT-4 has the potential to facilitate a variety of language-based technologies such as chatbots, virtual assistants, knowledge bases, and machine translation systems, which could improve and automate numerous language-based operations.

1. A visual assistant for people with visual impairment👏🏽 :

• OpenAI has partnered with Be My Eyes, an app designed for the visually impaired. The integration of GPT-4 into the app allows users to take a photo of their surroundings, and the AI can provide a detailed description of what's on the screen, including items such as clothing, plants, gym equipment, maps, and more.

2. GPT-4 for the sciences and in particular drug discovery :

• GPT-4 has the potential to revolutionize the field of drug discovery. The process of discovering new drugs involves screening millions of compounds to identify those that are most likely to be effective in treating a particular disease. This process is time-consuming and expensive, as many compounds need to be tested before one is found to be effective. GPT-4 can assist in this process by predicting the properties of compounds and identifying those that are most likely to be effective.

3. Revolutionizing Education with AI :

• GPT-4 has the potential to revolutionize the education sector by enhancing the learning experience of students. With its ability to understand natural language and generate coherent responses, GPT-4 can be used as a virtual teaching assistant. It can help students with their homework, answer their questions, and provide personalized feedback on their work.

4. Enhancing Code Generation with GPT-4 :

• GPT-4's natural language processing capabilities can also be applied to code generation. The AI language model can be trained to generate code based on natural language descriptions of what a program should do. This has the potential to significantly simplify the coding process, as developers can simply describe what they want the program to accomplish in natural language, and GPT-4 can generate the necessary code.

5. Khan's Academy :

• Khan Academy has teamed up with GPT-4 to create an AI assistant called Khanmigo, revolutionizing the world of education. This virtual mentor and teacher's assistant is set to assist both students and educators in the classroom. The platform started evaluating GPT-4 in 2022 and will soon offer the Khanmigo pilot program to a select group of individuals, with the general public on a waitlist.

• GPT-4's initial evaluations suggest it can help students understand the wider significance of their studies and teach them computer programming concepts. Khan Academy is also exploring ways for educators to use GPT-4 to design class materials. With GPT-4's advanced language capabilities, Khanmigo is set to take online learning to the next level, providing students with personalized learning experiences like never before.
