GPT-4

GPT-4 is the successor to GPT-3.5, the artificial intelligence chatbot. Not only can it generate readable text and images, but it can also calculate your tax deductions, for example, but it still 'hallucinates' (invents facts) and makes reasoning errors.
According to its creator, OpenAI, GPT-4 is much more reliable, creative, and can handle more nuanced commands than its predecessor. It can converse, generate readable text and produce new images and videos from a huge database.
GPT-4 is also 'steerable', which means that users can adjust the answer by, for example, asking for responses to take a certain form (for example, 'explain in the style of William Shakespeare').
But the earlier version of ChatGPT was also known for its "hallucinations", such as the detailed report of a match before it was played. In this sense, GPT-4 still has limitations and its creator warns users to be careful. GPT-4 is "still not completely reliable", although the number of hallucinations has been greatly reduced. Also, GPT-4 doesn't know much about what happened after September 2021, simply because the model was not trained with more recent data.

Microsoft and Google

Microsoft has invested at least $1 billion in OpenAI and has integrated AI chatbot technology into its Bing search engine. The number of visitors to the search engine increased as a result, see yesterday's Google Essentials. According to Microsoft, AI technology such as GPT-4 is the future of the Internet and has the potential to revolutionize Internet search. This was (and is) dominated by Google, which is currently struggling to respond to Microsoft's attack. Google seems to suffer from the law of diminishing returns. How Google will respond to this may become clear at Google's major conference, Google I/O on May 10, 2023.
