What is GPT-4 and how is it different from ChatGPT?

OpenAI, a research organization dedicated to creating artificial intelligence that can benefit humanity, has just released the fourth iteration of its highly popular GPT series, GPT-4. This new version was released on March 14, 2023, and it's available via API and for ChatGPT Plus users.


One of the main differences between GPT-4 and its predecessor, GPT-3.5, is that GPT-4 is a multimodal model, meaning that it can accept both image and text inputs and emit text outputs. This means that it can analyze the contents of an image and connect that information with relevant texts. For example, it can generate captions for images, describe scenes or objects in images, or answer questions based on images.


Another significant difference between GPT-4 and previous versions is the number of parameters it has. Parameters are numerical values that determine how the model processes inputs and outputs. GPT-4 has 1 trillion parameters, which is twice as many as GPT-3.5. Having more parameters means having more capacity to learn from data and generate diverse and coherent texts.


GPT-4 has also achieved human-level performance on various professional and academic benchmarks, such as passing a simulated bar exam with a score around the top 10% of test takers. In contrast, GPT-3.5’s score was around the bottom 10%. It also achieves state-of-the-art results on tasks such as summarization, translation, question answering, and text-to-video generation.


GPT-4's capabilities go beyond just language processing. It can generate, edit, and iterate with users on creative and technical writing tasks, such as composing songs, writing screenplays, or learning a user’s writing style. Additionally, GPT-4 is capable of handling over 25,000 words of text, allowing for use cases like long-form content creation, extended conversations, and document search and analysis.


While GPT-4 has the potential to bring about significant positive social impact, it also poses some ethical and societal challenges such as bias, misuse, and accountability. GPT-4 still struggles with social biases, hallucinations, and adversarial prompts. Inaccurate responses are known as “hallucinations”, which have been a challenge for many AI programs. Adversarial prompts are inputs that are designed to trick or manipulate the model into generating harmful or misleading outputs.


Another challenge that comes with GPT-4 is the cost of implementation and maintenance, as these technologies require specialized hardware and software. Additionally, GPT-4 may also require a steep learning curve for marketers to develop proficiency in its use.


In conclusion, GPT-4 is a powerful tool for language processing tasks, creative writing, and technical writing tasks, and has the potential to benefit society in many ways. However, it's important to address the ethical and societal challenges that come with its use to ensure that it's used in ways that align with our values and bring about positive social impact.
