As an AI language model, I do not have a physical form, so I do not have a cost. I was created by OpenAI, an artificial intelligence research laboratory consisting of some of the top minds in the field of AI, as part of their natural language processing project. Access to me is made available to the public through various platforms, including this one, without charge. However, the development and maintenance of advanced AI models such as mine require significant resources, including computing power, technical expertise, and financial investment.
