There are a number of famous AI chatbots, including Bard, ChatGPT, and the new Bing. These chatbots are known for their ability to mimic human conversation and provide information on a wide range of topics. Bard, for example, is Google's in-house large language model called PaLM2 and is considered one of the most sophisticated on the market. ChatGPT, on the other hand, is the original AI chatbot and has been widely popular since its release in late 2022. It is known for its simplicity and ability to produce unique content. The new Bing is also highly regarded for its exceptional performance, versatility, and free availability, as it uses OpenAI's cutting-edge GPT-4 language model. Overall, these AI chatbots have been shown to work well and are becoming increasingly popular as more and more people turn to them for information and assistance.
