On the 14th of March 2023, OpenAI released its groundbreaking new image- and text-understanding model, GPT-4. This achievement marks a significant advancement in the field of deep learning.
GPT-4 is now accessible to ChatGPT Plus subscribers, and developers interested in utilizing its API can join a waitlist. The cost of this cutting-edge technology is a competitive $0.03 per 1,000 “prompt” tokens and $0.06 per 1,000 “completion” tokens.
Interestingly, GPT-4 has already been operating within Microsoft’s Bing Chat, as well as supporting companies such as Stripe, Duolingo, Morgan Stanley, and Khan Academy in their respective innovations.
Surpassing GPT-3.5, GPT-4 is capable of understanding not only text but also images, demonstrating “human level” performance on various professional and academic benchmarks. This model has undergone a rigorous six-month refinement process using adversarial testing and lessons learned from previous iterations.
In collaboration with Microsoft, OpenAI developed a “supercomputer” within the Azure cloud specifically designed to train GPT-4. The improvements between GPT-3.5 and GPT-4 are evident in increased reliability, creativity, and the ability to handle nuanced instructions.
One of GPT-4’s most notable enhancements is its image comprehension ability. For instance, it can identify a Lightning Cable adapter from a photograph of an iPhone. However, this feature is being tested with a single partner, Be My Eyes, through their Virtual Volunteer feature.
Another significant advancement in GPT-4 is its “steerability.” OpenAI introduces “system” messages, allowing developers to guide the AI’s behaviour and style by providing specific instructions, leading to more controlled and predictable interactions.
It is important to acknowledge that GPT-4 is not without limitations. It may occasionally generate incorrect facts or make reasoning errors. However, GPT-4 has made progress in specific areas, such as adhering more closely to OpenAI’s policies regarding sensitive requests.

In conclusion, the introduction of GPT-4 opens up new possibilities in the field of artificial intelligence. As we continue to push the boundaries of our understanding, GPT-4 serves as a testament to the potential of AI in shaping our future.
