On March 14th, 2023, OpenAI introduced GPT-4, an upgraded version of its powerful artificial intelligence model. GPT-4 comes with significant improvements, enabling it to process both text and image data and respond accordingly to user inputs.
The upgrade marks a major advancement, surpassing GPT-3.5 in word processing, data formats, and capabilities. OpenAI has spent two years refining the deep learning stack, addressing bugs and AI alignment issues to create a more stable and efficient model.

One of the most notable enhancements is GPT-4's ability to accept prompts containing both images and text, allowing it to generate contextually relevant responses based on the provided images. While video processing hasn't been mentioned yet, it could be on the horizon.
OpenAI demonstrated GPT-4's potential during a developer livestream, showcasing how it could be used to build a Discord bot and create a functional website from a simple image and text input with impressive speed and accuracy.
GPT-4 is already available to Premium ChatGPT users, opening up new possibilities for developers. Despite the significant upgrade, OpenAI acknowledges that GPT-4 may still have some limitations, such as occasional false information or reasoning errors. Nevertheless, the improvements in trustworthiness and accuracy make GPT-4 a remarkable leap forward in the field of generative AI.
