The US tech firm OpenAI has released its latest version of the artificial intelligence chatbot ChatGPT.
The new model, GPT-4, is able to handle “much more nuanced instructions” than its predecessor, the GPT-3.5, its creators said.
Its improved capabilities will include the ability to respond to images and process up to 25,000 words – about eight times as much as ChatGPT.
It uses information from the internet to carry out requests and has been trained on back-and-forth conversations so it is capable of understanding follow-up questions, admitting its own mistakes and limitations and rejecting inappropriate requests.
According to OpenAI, GPT-4 has “more advanced reasoning skills” than ChatGPT, however, like its predecessors, GPT-4 is still not fully reliable and may “hallucinate” – a phenomenon where AI invents facts or makes reasoning errors.
