There are thousands of articles about the difference between ChatGPT version 3.5 versus version 4. However, we have a unique technology that allows you to embed ChatGPT on your website. This makes our requirements fairly unique. Hence, none of these existing comparisons really provide any value for us. We, therefore, decided to compare ChatGPT and its GPT3.5-turbo model against GPT4 in our chatbot to see the differences.
WARNING! GPT4 is 30 times more expensive than GPT3.5-turbo — so the quality and speed is not the only factor here. Unless you've got very deep pockets, you will obviously have to consider the price differences too.
