Late last year, a chatbot called ChatGPT caused a splash because of its ability to tackle complex subjects and also to generate speeches, songs and essays. Now, its creator, OpenAI, has launched a large language model called GPT-4 that it claims is more creative and collaborative than its predecessor, GPT-3.5, which underpins ChatGPT.
The new AI is able to recognise images and provide answers in text. Although image description is arguably its most eye-catching new feature, OpenAI is not releasing that functionality at launch due to fears it could be misused.
