The best overall AI chatbot is the new Bing due to its exceptional performance, versatility, and free availability. It uses OpenAI's cutting-edge GPT-4 language model, making it highly proficient in various language tasks, including writing, summarization, translation, and conversation. Moreover, it works like a search engine with information on current events. Another advantage of the new Bing is its availability to the public at no cost. Despite its immense popularity, the new Bing is still in its research and feedback-collection phase, making it an incredible resource for students, writers, and professionals who need a reliable and free AI chatbot. Although there are occasional capacity blocks, OpenAI is working on releasing a professional version of ChatGPT that will be quicker and always accessible at a monthly cost.
