GPT-3.5 and GPT-4 are both large language models developed by OpenAI, but they differ in several key areas:
Size and Architecture:
GPT-3.5: Has 175 billion parameters and a transformer architecture.
GPT-4: Is significantly larger and more complex, with an estimated 1 trillion parameters and a more advanced transformer architecture.
Capabilities:
- Text Generation: Both models are excellent at generating human-quality text, but GPT-4 is generally more creative and able to produce more diverse and nuanced responses.
According to OpenAI, ChatGPT-4 is “82 percent less likely to respond to requests for disallowed content and 40 percent more likely to produce factual responses than GPT-3.5 on our internal evaluations”.
- Problem-Solving: GPT-4 is better at solving complex problems and understanding nuanced instructions.
ChatGPT-4 also has a longer context window, or the amount of text it can process simultaneously. For example, you could ask ChatGPT-4 to analyze a document for you, and it can now process about 25,000 words at a time. Another version of the technology called ChatGPT-4 Turbo can process up to 128,000 words. With this feature, you could include a website link in your prompt and ask ChatGPT to consider that source when giving its answer.
- Multimodality: GPT-4 can process and generate text, code, and images, while GPT-3.5 is primarily text-based.
In the previous version, you needed to write a prompt using text to generate an output from ChatGPT. With version 4, you can still use text, but you can also offer an image or even a voice command to make a request from the application. OpenAI’s example of this new feature is that you could put in a picture of the inside of your refrigerator, and ChatGPT-4 could suggest recipes you could make with the ingredients in the image. You can also speak to ChatGPT-4, and the AI will generate a voice to speak to you. Multimodality also allows ChatGPT to handle more functions, like captioning or translating videos.
- Knowledge Base: GPT-4 has access to a larger knowledge base, allowing it to provide more informative and accurate responses.
In other news regarding ChatGPT upgrades, the program can now access the internet in real-time and provide summaries or respond to links. Previously, you could not access the internet in real-time using ChatGPT, and the program was limited to a data set containing information available before 2021. OpenAI released this update on September 27, 2023, allowing ChatGPT users the ability to discuss current events, ask ChatGPT questions about websites, or suggest links to find more information. Currently, this new feature is only available to paid ChatGPT subscribers, but it is not exclusive to GPT-4.
Performance:
Benchmarks: GPT-4 has consistently outperformed GPT-3.5 on various benchmarks, demonstrating its superior capabilities.
Human-Level Performance: In certain tests, GPT-4 has achieved human-level performance, surpassing previous AI models.
What is GPT-4 used for?
Some of the things you can use ChatGPT for, such as solving math problems, writing essays, translating languages, or writing computer code. However, as the Microsoft research team pointed out, this technology has the potential for even greater applications. Here are some of the ways companies are using ChatGPT:
