OpenAI has announced the development of an improved version of the artificial intelligence behind ChatGPT, called GPT-4. This new version can use images as input in addition to text, making it an especially useful tool for the blind and visually impaired. Microsoft already applies GPT-4 in the search engine’s Bing chatbot. GPT-4’s enhanced text features are initially available through the paid subscription ChatGPT Plus and the API for software developers. GPT-4 is more reliable, more creative and can handle much more nuanced instructions than its predecessor.

Improvements in model

OpenAI has made improvements to its language models and AI systems in recent months, based in part on feedback from millions of ChatGPT users. As a result, GPT-4 scores much better in simulated exams than its predecessor GPT-3.5. Users can also send images to GPT-4, such as photos, scans or screenshots, and ChatGPT can respond by, for example, explaining what is funny about a picture or describing or summarizing information from the images. OpenAI is testing these features in collaboration with Be My Eyes, an app that makes the world more accessible to the blind and visually impaired.

Model is more creative

GPT-4 has become a lot more creative in writing, according to OpenAI, for example, in composing songs, writing scenarios and learning the user’s writing style. In addition, GPT-4 can generate eight times longer texts, up to a maximum of 25,000 words. It also responds 82% less quickly to requests directed at “unauthorized cases” and produces 40% more factual responses than version 3.5. The company also worked with more than 50 experts in safety and security.

GPT-4 has limitations

OpenAI admits that GPT-4 still has limitations, such as social biases, hallucinations and hostile reactions. The AI model was trained with the supercomputers of Microsoft, which previously invested billions in OpenAI. Microsoft has already upgraded Bing’s chatbot to GPT-4 for several weeks and increased the limit on the number of questions to the chatbot from six to 15 in a row.
