OpenAI Unveils GPT-4: A Multimodal AI Revolutionizing the Future of AI Applications

Revolutionizing AI with Multimodal Understanding and Advanced Applications

OpenAI, a leading AI research organization, has recently launched GPT-4, a groundbreaking image and text-understanding AI model. Dubbed as the latest milestone in OpenAI's deep learning journey, GPT-4's state-of-the-art capabilities are already being utilized by big names such as Microsoft, Stripe, Duolingo, Morgan Stanley, and Khan Academy. Let's explore GPT-4's impressive features, its applications, and how it surpasses its predecessor, GPT-3.5.

GPT-4: A Quantum Leap in AI Capabilities

GPT-4 is now accessible to OpenAI's paying users via ChatGPT Plus, with a usage cap and a waitlist for developers seeking API access. Notably, GPT-4's pricing is $0.03 per 1,000 "prompt" tokens (about 750 words) and $0.06 per 1,000 "completion" tokens (again, about 750 words).

What sets GPT-4 apart from GPT-3.5 is its ability to accept image and text inputs, performing at a "human level" on various professional and academic benchmarks. For instance, GPT-4 has scored in the top 10% on a simulated bar exam, compared to GPT-3.5's score, which landed in the bottom 10%. This significant improvement is a result of only six months of iterative alignment, utilizing lessons from OpenAI's internal adversarial testing program and ChatGPT.

Powerful Applications Across Industries

Several industry giants are already leveraging GPT-4's capabilities. Microsoft's Bing Chat, co-developed with OpenAI, is confirmed to be running on GPT-4. Stripe is using the AI to scan business websites and provide summaries to customer support staff, while Duolingo is integrating GPT-4 into a new language learning subscription tier. Moreover, Morgan Stanley is developing a GPT-4-powered system for retrieving company document information for financial analysts, and Khan Academy is working on an automated tutor using GPT-4.

Image Understanding and Steerability Enhancements

A remarkable feature of GPT-4 is its ability to understand and interpret images. Currently, OpenAI is testing this image understanding capability with a single partner, Be My Eyes. With GPT-4, Be My Eyes' new Virtual Volunteer feature can answer questions about images sent to it, identifying objects and even suggesting recipes based on the contents of a refrigerator.

In addition to image understanding, GPT-4 introduces "system" messages, a new API capability that allows developers to set specific directions and styles for AI interactions. These instructions establish boundaries and set the tone for the AI's responses, resulting in more precise and nuanced outputs.

Room for Improvement

Despite its impressive advancements, GPT-4 still has its limitations. It may "hallucinate" facts or make reasoning errors with high confidence. However, OpenAI has made significant improvements, with GPT-4 being 82% less likely to respond to "disallowed" content compared to GPT-3.5 and adhering to OpenAI's policies on sensitive requests 29% more often.

GPT-4 is undoubtedly revolutionizing the AI landscape with its enhanced capabilities, multimodal understanding, and wide range of applications across various industries. OpenAI's continuous improvements and the collective efforts of the community building on top of the model will propel GPT-4 towards becoming an invaluable tool in improving people's lives through AI-powered applications.
