Microsoft has announced that its AI-powered Bing Chat is now available to all users in open preview mode, following a limited preview that began three months ago. The chatbot uses the GPT-4 language learning model to provide human-like text responses to users’ queries. Under the open preview, Microsoft has added several new features to the chatbot, including the incorporation of visual elements such as graphs and charts into responses, and the ability to read and output text based on images.
